( 三洋電機株式会社 , San'yō Denki Kabushiki-gaisha ) is a Japanese electronics manufacturer founded in 1947 by Toshio Iue , the brother-in-law of Kōnosuke Matsushita , the founder of Matsushita Electric Industrial, now known as Panasonic . Iue left Matsushita Electric to start his own business, acquiring some of its equipment to produce bicycle generator lamps. In 1950,

196-763: A 51% majority stake in Chinese company Hefei Royalstar Sanyo, a 2000 joint venture between Sanyo and Chinese government investment company Hefei, was purchased by American multinational manufacturer Whirlpool Corporation for $ 552 million. The Sanyo HIT ( Heterojunction with Intrinsic Thin layer ) solar cell is composed of a mono thin crystalline silicon wafer surrounded by ultra-thin amorphous silicon layers. Sanyo Energy opened its solar module assembly plants in Hungary and in Mexico in 2004, and in 2006 it produced solar modules worth $ 213 million. In 2007, Sanyo completed

294-413: A ROM firmware chip) loads the operating system from the disk in drive A: . By modern standards CP/M is primitive, owing to the extreme constraints on program size. With version 1.0 there is no provision for detecting a changed disk. If a user changes disks without manually rereading the disk directory the system writes on the new disk using the old disk's directory information, ruining the data stored on

392-468: A competitor in the spreadsheet market in the MS-DOS world. AutoCAD , a CAD application from Autodesk debuted on CP/M. A host of compilers and interpreters for popular programming languages of the time (such as BASIC , Borland 's Turbo Pascal , FORTRAN and even PL/I ) were available, among them several of the earliest Microsoft products. CP/M software often came with installers that adapted it to

490-528: A corporation change-of-name filing to Digital Research, Inc. By September 1981, Digital Research had sold more than 250,000 CP/M licenses; InfoWorld stated that the actual market was likely larger because of sublicenses. Many different companies produced CP/M-based computers for many different markets; the magazine stated that "CP/M is well on its way to establishing itself as the small-computer operating system". The companies chose to support CP/M because of its large library of software. The Xerox 820 ran

588-780: A directory except those marked with the SYS attribute), DIRSYS / DIRS (list files marked with the SYS attribute in the directory), ERASE / ERA (delete a file), RENAME / REN (rename a file), TYPE / TYP (display contents of an ASCII character file), and USER / USE (change user number) as built-in commands: CP/M 3 allows the user to abbreviate the built-in commands. Transient commands in CP/M 3 include COPYSYS , DATE , DEVICE , DUMP , ED , GET , HELP , HEXCOM , INITDIR , LINK , MAC , PIP, PUT , RMAC , SET , SETDEF , SHOW , SID , SUBMIT , and XREF . The Basic Disk Operating System, or BDOS, provides access to such operations as opening

686-464: A directory or ERA to delete a file) or loads and starts an executable file of the given name (transient commands such as PIP.COM to copy files or STAT.COM to show various file and system information). Third-party applications for CP/M are also essentially transient commands. The BDOS, CCP and standard transient commands are the same in all installations of a particular revision of CP/M, but the BIOS portion

784-449: A dozen different CP/M systems, plus two generic versions. The operating system was described as a " software bus ", allowing multiple programs to interact with different hardware in a standardized way. Programs written for CP/M were typically portable among different machines, usually requiring only the specification of the escape sequences for control of the screen and printer. This portability made CP/M popular, and much more software

882-429: A file, output to the console, or printing. Application programs load processor registers with a function code for the operation, and addresses for parameters or memory buffers , and call a fixed address in memory. Since the address is the same independent of the amount of memory in the system, application programs run the same way for any type or configuration of hardware. The Basic Input Output System or BIOS, provides

980-419: A financial crisis as a result of its huge investment in the semiconductor business. In 2009, Sanyo was acquired by Panasonic, and in 2011, it was fully consolidated into Panasonic and its brand disappeared. The company still exists as a legal entity for the purpose of winding up its affairs. Sanyo was founded when Toshio Iue , the brother-in-law of Konosuke Matsushita and also a former Matsushita employee,

1176-560: A former NHK anchorwoman who was appointed chairwoman of the company, stepped down in March 2007. The President, Toshimasa Iue, also stepped down in April of that year; Seiichiro Sano was appointed to head the company effective April 2007. In October 2007, Sanyo cancelled a 110 billion yen sale of its semiconductor business, blaming the global credit crisis for the decision and stating that after exploring its other options, it had decided to keep

1274-451: A joint company, known as Sanyo Eneos Solar Co., Ltd., for the production and sale of thin-film solar panels . The new joint company began production and sales at an initial scale of 80 MW, while gradually increasing its production capacity. For this joint project, Sanyo drew on its solar cell technologies, based on the technology acquired through the development of the HIT solar cell. Sanyo

1372-465: A new unit at its solar module plant in Hungary that was to triple its annual capacity to 720,000 units in 2008. Plans to expand production were based on rising demands for Sanyo Hungary products, whose leading markets are Germany , Italy , Spain and Scandinavia . The plant at Dorog , outside Budapest , became Sanyo's largest solar module production facility in the world. Germany, Italy, Spain and

1470-478: A part of the Amateur Computer Club of New Jersey . ZCPR2 was released on 14 February 1983. It was released as a set of ten disks from SIG/M. ZCPR2 was upgraded to 2.3, and also was released in 8080 code, permitting the use of ZCPR2 on 8080 and 8085 systems. ZCPR3 was released on 14 July 1984, as a set of nine disks from SIG/M. The code for ZCPR3 could also be compiled (with reduced features) for

1568-516: A prevailing naming scheme of the time, as in Kildall's PL/M language, and Prime Computer's PL/P ( Programming Language for Prime ), both suggesting IBM's PL/I ; and IBM's CP/CMS operating system, which Kildall had used when working at the NPS. This renaming of CP/M was part of a larger effort by Kildall and his wife with business partner, Dorothy McEwen to convert Kildall's personal project of CP/M and

1666-508: A program was not standardized, so that there is no single option character that differentiated options from file names. Different programs can and do use different characters. The CP/M Console Command Processor includes DIR , ERA , REN , SAVE , TYPE , and USER as built-in commands. Transient commands in CP/M include ASM , DDT , DUMP , ED , LOAD , MOVCPM  [ pl ] , PIP , STAT , SUBMIT , and SYSGEN . CP/M Plus (CP/M Version 3) includes DIR (display list of files from

1764-627: A purchase of the Fisher Electronics audio equipment manufacturer by Sanyo in May 1975. Under Ladd's leadership, the Fisher Corporation under Sanyo grew to be a multi-million dollar leader in the consumer electronics industry . The new, profitable Fisher Corporation moved its headquarters from New York to Ladd's Los Angeles. Ladd was named president and CEO of the combined Sanyo / Fisher Corporation in 1977, serving until 1987. Ladd

1862-699: A range of Android TV sets known as the Sanyo Kaizen Series. Sanyo worked with Energy Efficiency Services Limited to develop a 1.5-ton inverter air conditioner (AC) with an Indian Seasonal Energy Efficiency Ratio (ISEER) of 5.2. Distribution of these air conditioners began in September 2017. On April 4, 2019, Sanyo launched a new AC range exclusively on Amazon . Though founded in Japan, Sanyo has sold TVs in America for over 50 years; Sanyo TV USA

1960-840: A relocating assembler and linker. CP/M 3 was available for the last generation of 8-bit computers, notably the Amstrad PCW, the Amstrad CPC , the ZX Spectrum +3 , the Commodore 128 , MSX machines and the Radio Shack TRS-80 Model 4 . There were versions of CP/M for some 16-bit CPUs as well. The first version in the 16-bit family was CP/M-86 for the Intel 8086 in November 1981. Kathryn Strutynski

2058-494: A series of unprofitable quarters, Sanyo's story would go full circle as it was acquired in 2009 by Panasonic Corporation , the firm where Iue originally worked at alongside his brother-in-law, Konosuke Matsushita. CP/M CP/M , originally standing for Control Program/Monitor and later Control Program for Microcomputers , is a mass-market operating system created in 1974 for Intel 8080 / 85 -based microcomputers by Gary Kildall of Digital Research, Inc. CP/M

2156-530: A user-installed overlay containing all the code required to access a particular machine's serial port. WordStar, one of the first widely used word processors , and dBase , an early and popular database program for microcomputers, were originally written for CP/M. Two early outliners , KAMAS (Knowledge and Mind Amplification System) and its cut-down successor Out-Think (without programming facilities and retooled for 8080/V20 compatibility) were also written for CP/M, though later rewritten for MS-DOS. Turbo Pascal ,

2254-540: A wide variety of computers. The source code for BASIC programs was easily accessible, and most forms of copy protection were ineffective on the operating system. A Kaypro II owner, for example, would obtain software on Xerox 820 format, then copy it to and run it from Kaypro-format disks. The lack of standardized graphics support limited video games , but various character and text-based games were ported , such as Telengard , Gorillas , Hamurabi , Lunar Lander , along with early interactive fiction including

2352-418: Is a disk operating system and its purpose is to organize files on a magnetic storage medium, and to load and run programs stored on a disk. Initially confined to single-tasking on 8-bit processors and no more than 64 kilobytes of memory, later versions of CP/M added multi-user variations and were migrated to 16-bit processors . The combination of CP/M and S-100 bus computers became an early standard in

2450-583: Is also responsible for the construction of the Solar Ark . Sanyo pioneered the production of nickel cadmium batteries in 1964, nickel metal hydride batteries (NiMh) in 1990, lithium-ion batteries in 1994, and lithium polymer batteries in 1999. In 2000, it acquired Toshiba 's NiMh business, including the Takasaki factory. Since the acquisition of Sanyo by Panasonic, ownership of the Takasaki factory

2548-451: Is always adapted to the particular hardware. Adding memory to a computer, for example, means that the CP/M system must be reinstalled to allow transient programs to use the additional memory space. A utility program (MOVCPM) is provided with system distribution that allows relocating the object code to different memory areas. The utility program adjusts the addresses in absolute jump and subroutine call instructions to new addresses required by

2646-534: The Zork series and Colossal Cave Adventure . Text adventure specialist Infocom was one of the few publishers to consistently release their games in CP/M format. Lifeboat Associates started collecting and distributing user-written "free" software. One of the first was XMODEM , which allowed reliable file transfers via modem and phone line. Another program native to CP/M was the outline processor KAMAS. The read/write memory between address 0100 hexadecimal and

2744-543: The Eneloop Low self-discharge NiMH battery , a "hybrid" rechargeable NiMH ( Nickel-metal hydride battery ) which, unlike typical NiMH cells, can be used from-the-package without an initial recharge cycle and retain a charge significantly longer than batteries using standard NiMH battery design. The Eneloop line competes against similar products such as Rayovac 's "Hybrid Rechargeable" line. On November 24, 2006, Sanyo announced heavy losses and job cuts. Tomoyo Nonaka ,

2842-589: The PDP-11 and OS/8 for the PDP-8 . Commands take the form of a keyword followed by a list of parameters separated by spaces or special characters. Similar to a Unix shell builtin , if an internal command is recognized, it is carried out by the CCP itself. Otherwise it attempts to find an executable file on the currently logged disk drive and (in later versions) user area, loads it, and passes it any additional parameters from

2940-529: The TOPS-10 operating system of the DECsystem-10 mainframe computer , which Kildall had used as a development environment. An early outside licensee of CP/M was Gnat Computers , an early microcomputer developer out of San Diego, California . In 1977, the company was granted the license to use CP/M 1.0 for any micro they desired for $ 90. Within the year, demand for CP/M was so high that Digital Research

3038-486: The extension .COM on disk. The BIOS directly controls hardware components other than the CPU and main memory. It contains functions such as character input and output and the reading and writing of disk sectors. The BDOS implements the CP/M file system and some input/output abstractions (such as redirection) on top of the BIOS. The CCP takes user commands and either executes them directly (internal commands such as DIR to show

3136-494: The 1970s; annual sales grew from $ 71.4 million (equivalent to $ 520,078,000 in 2023) in 1972 to $ 855 million (equivalent to $ 3,994,071,000 in 2023) in 1978. After a fairly slow selling line in their own V-Cord video format, Sanyo adopted Sony 's Betamax video cassette format around 1977 with initial success, including SuperBeta and Beta Hi-Fi models. From around 1984 onwards, production switched entirely to VHS . In 1976, Sanyo expanded their North American presence with

3234-441: The 7-bit boundary. In the 8-bit versions, while running, the CP/M operating system loaded into memory has three components: The BIOS and BDOS are memory-resident, while the CCP is memory-resident unless overwritten by an application, in which case it is automatically reloaded after the application finished running. A number of transient commands for standard utilities are also provided. The transient commands reside in files with

3332-429: The 8080 I/O address space. All of these variations in the hardware are concealed from other modules of the system by use of the BIOS, which uses standard entry points for the services required to run CP/M such as character I/O or accessing a disk block. Since support for serial communication to a modem is very rudimentary in the BIOS or may be absent altogether, it is common practice for CP/M programs that use modems to have

3430-421: The 8080 and would run on systems that did not have the requisite Z80 microprocessor. Features of ZCPR as of version 3 included shells, aliases, I/O redirection, flow control, named directories, search paths, custom menus, passwords, and online help. In January 1987, Richard Conn stopped developing ZCPR, and Echelon asked Jay Sage (who already had a privately enhanced ZCPR 3.1) to continue work on it. Thus, ZCPR 3.3

3528-429: The CP/M base included Robert "Bob" Silberstein and David "Dave" K. Brown. CP/M originally stood for "Control Program/Monitor", a name which implies a resident monitor —a primitive precursor to the operating system. However, during the conversion of CP/M to a commercial product, trademark registration documents filed in November 1977 gave the product's name as "Control Program for Microcomputers". The CP/M name follows

3626-645: The Digital Research distributed core of CP/M (BDOS, CCP, core transient commands) did not use any of the Z80-specific instructions, many Z80-based systems used Z80 code in the system-specific BIOS, and many applications were dedicated to Z80-based CP/M machines. Digital Research subsequently partnered with Zilog and American Microsystems to produce Personal CP/M, a ROM-based version of the operating system aimed at lower-cost systems that could potentially be equipped without disk drives. First featured in

3724-659: The Executive Vice President and COO of Sanyo Corporation. Ladd introduced the Sanyo brand to the United States in 1970. The ambition to sell Sanyo products worldwide was realized in the mid-1970s after Sanyo introduced home audio equipment, car stereos and other consumer electronics to the North American market. The company embarked on a heavy television-based advertising campaign. Ladd negotiated

3822-589: The IBM PC after DRI threatened legal action, it never overtook Microsoft's system. Most customers were repelled by the significantly greater price IBM charged for CP/M-86 over PC DOS ( US$ 240 and US$ 40, respectively). When Digital Equipment Corporation (DEC) put out the Rainbow 100 to compete with IBM, it came with CP/M-80 using a Z80 chip, CP/M-86 or MS-DOS using an 8088 microprocessor, or CP/M-86/80 using both. The Z80 and 8088 CPUs ran concurrently. A benefit of

3920-471: The IBM-compatible platform, and it never regained its former popularity. Byte magazine, at the time one of the leading industry magazines for microcomputers, essentially ceased covering CP/M products within a few years of the introduction of the IBM PC. For example, in 1983 there were still a few advertisements for S-100 boards and articles on CP/M software, but by 1987 these were no longer found in

4018-576: The Intel 8080 processor into .A86 source code for the Intel 8086. The translator would also optimize the output for code size and take care of calling conventions, so that CP/M-80 and MP/M-80 programs could be ported to the CP/M-86 and MP/M-86 platforms automatically. XLT86 itself was written in PL/I-80 and was available for CP/M-80 platforms as well as for VAX/VMS . Many expected that CP/M would be

4116-489: The Intel-contracted PL/M compiler into a commercial enterprise. The Kildalls intended to establish the Digital Research brand and its product lines as synonymous with "microcomputer" in the consumer's mind, similar to what IBM and Microsoft together later successfully accomplished in making " personal computer " synonymous with their product offerings. Intergalactic Digital Research, Inc. was later renamed via

The growing demand for home appliances and washing machines would fuel Sanyo's growth through the 1950s. Iue retired and handed the presidency of Sanyo to his brother in 1968. During his retirement, he worked to promote development of Awaji Island and died in 1969. After

4312-517: The NIAT, a custom handheld computer designed for A. C. Nielsen 's internal use with 1  MB of SSD memory. In 1979, a multi-user compatible derivative of CP/M was released. MP/M allowed multiple users to connect to a single computer, using multiple terminals to provide each user with a screen and keyboard. Later versions ran on 16-bit processors. The last 8-bit version of CP/M was version 3, often called CP/M Plus, released in 1983. Its BDOS

4410-686: The OS and BIOS (this was also a common problem in early DOS machines). Bill Gates claimed that the Apple II with a Z-80 SoftCard was the single most-popular CP/M hardware platform. Many different brands of machines ran the operating system, some notable examples being the Altair 8800 , the IMSAI 8080 , the Osborne 1 and Kaypro luggables , and MSX computers. The best-selling CP/M-capable system of all time

4508-565: The Rainbow was that it could continue to run 8-bit CP/M software, preserving a user's possibly sizable investment as they moved into the 16-bit world of MS-DOS. A similar dual-processor adaption for the CompuPro System 816  [ sr ] was named CP/M 8-16 . The CP/M-86 adaptation for the 8085/8088-based Zenith Z-100 also supported running programs for both of its CPUs. Soon following CP/M-86, another 16-bit version of CP/M

4606-502: The S83 was quoted as $ 32 in 1,000 unit quantities. On most machines the bootstrap was a minimal bootloader in ROM combined with some means of minimal bank switching or a means of injecting code on the bus (since the 8080 needs to see boot code at Address 0 for start-up, while CP/M needs RAM there); for others, this bootstrap had to be entered into memory using front-panel controls each time

4704-679: The Sanyo name to the United States in the early 1970s. In 1982, Sanyo started selling the MBC-1000 series of CP/M computers. In 1983, it introduced the MBC-550 PC, the lowest-cost IBM PC compatible personal computer available at the time, but its lack of full compatibility drove Sanyo from the market and no follow-on models were released. An article on "Sanyo Style" written in 1992 described that Sanyo utilizes an extensive socialization process for new employees, so that they will be acclimatized to Sanyo's corporate culture. New employees take

4802-699: The Scandinavian countries. The plant at Dorog , outside Budapest , will be Sanyo Electric's largest facility producing solar modules in the entire world. In late September 2008, Sanyo announced its decision to build a manufacturing plant for solar ingots and wafers (the building blocks for silicon solar cells) in Inagi , Japan. The plant began operating in October 2009 and was to reach its full production capacity of 70 megawatts (MW) of solar wafers per year by April 2010. Sanyo and Nippon Oil decided to launch

4900-543: The Sharp MZ-800, a cassette-based system with optional disk drives, Personal CP/M was described as having been "rewritten to take advantage of the enhanced Z-80 instruction set" as opposed to preserving portability with the 8080. American Microsystems announced a Z80-compatible microprocessor, the S83, featuring 8 KB of in-package ROM for the operating system and BIOS, together with comprehensive logic for interfacing with 64-kilobit dynamic RAM devices.

More recently, though, Sanyo decided against supporting Sony's format, the Blu-ray Disc , and instead gave its backing to Toshiba 's HD DVD . This was ultimately unsuccessful, however, as Sony's Blu-ray triumphed. In North America, Sanyo manufactured CDMA cellular phones exclusively for Sprint 's Sprint PCS brand in

5194-536: The United States and for Bell Mobility in Canada. The 2004 Chūetsu earthquake severely damaged Sanyo's semiconductor plant and as a result Sanyo recorded a huge financial loss for that year. The 2005 fiscal year financial results saw a 205 billion yen net income loss. The same year the company announced a restructuring plan called the Sanyo Evolution Project, launching a new corporate vision to make

5292-402: The ancestor of Borland Delphi , and Multiplan , the ancestor of Microsoft Excel , also debuted on CP/M before MS-DOS versions became available. VisiCalc , the first-ever spreadsheet program, was made available for CP/M. Another company, Sorcim , created its SuperCalc spreadsheet for CP/M, which would go on to become the market leader and de facto standard on CP/M. Supercalc would go on to be

5390-420: The basic concepts and mechanisms of early versions of MS-DOS resembled those of CP/M. Internals like file-handling data structures were identical, and both referred to disk drives with a letter ( A: , B: , etc.). MS-DOS's main innovation was its FAT file system. This similarity made it easier to port popular CP/M software like WordStar and dBase . However, CP/M's concept of separate user areas for files on

5488-531: The blocking and deblocking and the management of a disk buffer area is handled by model-specific code in the BIOS. Customization is required because hardware choices are not constrained by compatibility with any one popular standard. For example, some manufacturers designed built-in integrated video display systems, while others relied on separate computer terminals. Serial ports for printers and modems can use different types of UART chips, and port addresses are not fixed. Some machines use memory-mapped I/O instead of

On November 2, 2008, Sanyo and Panasonic announced that they have agreed on the main points of a proposed buyout that would make Sanyo a subsidiary of Panasonic. They became a subsidiary of Panasonic on December 21, 2009. In 2010, Sanyo sold its semiconductor operations to ON Semiconductor . On July 29, 2010, Panasonic reached an agreement to acquire

5684-452: The command line. These are referred to as "transient" programs. On completion, BDOS will reload the CCP if it has been overwritten by application programs — this allows transient programs a larger memory space. The commands themselves can sometimes be obscure. For instance, the command to duplicate files is named PIP (Peripheral-Interchange-Program), the name of the old DEC utility used for that purpose. The format of parameters given to

When a ship he was on exploded, with Toshio barely escaping with his life, he took a job at an electric plant run by Konosuke Matsushita , who

5880-495: The company was established. Sanyo began to diversify in the 1960s, having launched Japan's first spray-type washing machine in 1953. In the 2000s, it was known as one of the 3S along with Sony and Sharp . Sanyo also focused on solar cell and lithium battery businesses. In 1992, it developed the world's first hybrid solar cell , and in 2002, it had a 41% share of the global lithium-ion battery market. In its heyday in 2003, Sanyo had sales of about ¥2.5 trillion. However, it fell into

5978-547: The corporation into an environmental company, plowing investment into strong products like rechargeable batteries , solar photovoltaics , air conditioning , hybrid car batteries and key consumer electronics such as the Xacti camera, projectors and mobile phones . Sanyo posted signs of recovery after the announcement of positive operating income of 2.6 billion yen. Sanyo remains the world number one producer of rechargeable batteries. Recent product innovations in this area include

This avoids overwriting the disk but requires a reboot and loss of the data to be stored on disk. The majority of the complexity in CP/M is isolated in the BDOS, and to a lesser extent, the CCP and transient commands. This meant that by porting

On July 11, 2017, Sanyo launched its range of smart TVs on Amazon Prime Day . In August 2017, Sanyo unveiled its NXT range of LED televisions exclusively on Flipkart . In December 2017, Sanyo introduced its first 4K smart TV range in India. In September 2019, Sanyo introduced

6272-532: The following components: The only hardware system that CP/M, as sold by Digital Research, would support was the Intel 8080 Development System. Manufacturers of CP/M-compatible systems customized portions of the operating system for their own combination of installed memory, disk drives, and console devices. CP/M would also run on systems based on the Zilog Z80 processor since the Z80 was compatible with 8080 code. While

6370-409: The home market had been largely unsuccessful and most CP/M software was too expensive for home users. In 1986 the magazine stated that Kaypro had stopped production of 8-bit CP/M-based models to concentrate on sales of MS-DOS compatible systems, long after most other vendors had ceased production of new equipment and software for CP/M. CP/M rapidly lost market share as the microcomputing market moved to

6468-460: The keyboard and conveys results to the terminal. CP/M itself works with either a printing terminal or a video terminal. All CP/M commands have to be typed in on the command line . The console most often displays the A>; prompt, to indicate the current default disk drive. When used with a video terminal, this is usually followed by a blinking cursor supplied by the terminal. The CCP awaits input from

Upon Japan's defeat in the war, the General Headquarters of Allied Forces requested a change in the management of Matsushita, with one of its senior executives required to step down. Iue decided to step down so that Matsushita could continue as the head of the company. After his resignation from Matsushita, Iue

This significantly reduced the development time needed to support new machines, and was one of the main reasons for CP/M's widespread use. Today this sort of abstraction is common to most OSs (a hardware abstraction layer ), but at the time of CP/M's birth, OSs were typically intended to run on only one machine platform, and multilayer designs were considered unnecessary. The Console Command Processor, or CCP, accepts input from

6762-480: The lowest address of the BDOS was the Transient Program Area (TPA) available for CP/M application programs. Although all Z80 and 8080 processors could address 64 kilobytes of memory, the amount available for application programs could vary, depending on the design of the particular computer. Some computers used large parts of the address space for such things as BIOS ROMs, or video display memory. As

6860-434: The lowest level functions required by the operating system. These include reading or writing single characters to the system console and reading or writing a sector of data from the disk. The BDOS handles some of the buffering of data from the diskette, but before CP/M 3.0 it assumes a disk sector size fixed at 128 bytes, as used on single-density 8-inch floppy disks. Since most 5.25-inch disk formats use larger sectors,

6958-513: The magazine. Later versions of CP/M-86 made significant strides in performance and usability and were made compatible with MS-DOS. To reflect this compatibility the name was changed, and CP/M-86 became DOS Plus , which in turn became DR-DOS . ZCPR (the Z80 Command Processor Replacement) was introduced on 2 February 1982 as a drop-in replacement for the standard Digital Research console command processor (CCP) and

7056-523: The microcomputer industry. This computer platform was widely used in business through the late 1970s and into the mid-1980s. CP/M increased the market size for both hardware and software by greatly reducing the amount of programming required to port an application to a new manufacturer's computer. An important driver of software innovation was the advent of (comparatively) low-cost microcomputers running CP/M, as independent programmers and hackers bought them and shared their creations in user groups . CP/M

7154-434: The new location of the operating system in processor memory. This newly patched version can then be saved on a new disk, allowing application programs to access the additional memory made available by moving the system components. Once installed, the operating system (BIOS, BDOS and CCP) is stored in reserved areas at the beginning of any disk which can be used to boot the system. On start-up, the bootloader (usually contained in

7252-451: The operating system because "where there are literally thousands of programs written for it, it would be unwise not to take advantage of it", Xerox said. (Xerox included a Howard W. Sams CP/M manual as compensation for Digital Research's documentation, which InfoWorld described as atrocious, incomplete, incomprehensible, and poorly indexed. ) By 1984, Columbia University used the same source code to build Kermit binaries for more than

7350-422: The purchase of Whirlpool Corporation 's television business, Warwick Electronics, which manufactured televisions for Sears . In 1986, Sanyo's U.S. affiliate merged with Fisher to become Sanyo Fisher (U.S.A.) Corporation (later renamed Sanyo Fisher Company). The mergers made the entire organization more efficient, but also resulted in the departure of certain key executives, including Ladd, who had first introduced

7448-462: The remaining shares of Panasonic Electric Works and Sanyo shares for $ 9.4 billion. By March 2012, parent company Panasonic plans to terminate the Sanyo brand, however it will remain on some of the products where the Sanyo brand still holds value to consumers. In the same month, Sanyo's Southeast Asian unit, responsible for the manufacturing of consumer electric appliances in the region, was announced to be formally acquired by Haier . In August 2013,

7546-492: The retail chain. Consumer Reports commented in 2018 that Sanyo TVs "seem to turn up mostly in Walmart stores, almost as a private label for the retailer." Sanyo is also known for its thermal management sector, Sanyo Denki, which makes high speed, large airflow , high static pressure DC fans sold under the moniker "San Ace", a product line mainly geared towards the enterprise market. As of October 2020, Sanyo Denki holds

7644-513: The same disk was never ported to MS-DOS. Since MS-DOS had access to more memory (as few IBM PCs were sold with less than 64 KB of memory, while CP/M could run in 16 KB if necessary), more commands were built into the command-line shell , making MS-DOS somewhat faster and easier to use on floppy-based computers. Although one of the first peripherals for the IBM PC was a SoftCard-like expansion card that let it run 8-bit CP/M software, InfoWorld stated in 1984 that efforts to introduce CP/M to

7742-513: The standard operating system for 16-bit computers. In 1980 IBM approached Digital Research, at Bill Gates ' suggestion, to license a forthcoming version of CP/M for its new product, the IBM Personal Computer. Upon the failure to obtain a signed non-disclosure agreement , the talks failed, and IBM instead contracted with Microsoft to provide an operating system. The resulting product, MS-DOS , soon began outselling CP/M. Many of

7840-616: The system was started. CP/M used the 7-bit ASCII set. The other 128 characters made possible by the 8-bit byte were not standardized. For example, one Kaypro used them for Greek characters, and Osborne machines used the 8th bit set to indicate an underlined character. WordStar used the 8th bit as an end-of-word marker. International CP/M systems most commonly used the ISO 646 norm for localized character sets, replacing certain ASCII characters with localized characters rather than adding them beyond

7938-411: The user. A CCP internal command, of the form drive letter followed by a colon, can be used to select the default drive. For example, typing B: and pressing enter at the command prompt changes the default drive to B, and the command prompt then becomes B> to indicate this change. CP/M's command-line interface was patterned after the operating systems from Digital Equipment , such as RT-11 for

8036-597: The world record for both rotational speed and static pressure of various dimensions and models. Some notable records are: Sanyo was the primary sponsor of the Penrith Panthers in the National Rugby League in Australia from 2000 to 2012. In Formula One , the company sponsored Benetton from 1989 to 1995, Williams from 1995 to 1997 and Stewart Grand Prix from 1997 to 1999. In football ,

8134-711: Was CP/M-68K for the Motorola 68000 . The original version of CP/M-68K in 1982 was written in Pascal/MT+68k , but it was ported to C later on. CP/M-68K, already running on the Motorola EXORmacs systems, was initially to be used in the Atari ST computer, but Atari decided to go with a newer disk operating system called GEMDOS . CP/M-68K was also used on the SORD M68 and M68MX computers. In 1982, there

8232-454: Was able to increase the license to tens of thousands of dollars. Under Kildall's direction, the development of CP/M 2.0 was mostly carried out by John Pierce in 1978. Kathryn Strutynski , a friend of Kildall from Naval Postgraduate School (NPS), became the fourth employee of Digital Research Inc. in early 1979. She started by debugging CP/M 2.0, and later became influential as key developer for CP/M 2.2 and CP/M Plus. Other early developers of

8330-466: Was also a port from CP/M-68K to the 16-bit Zilog Z8000 for the Olivetti M20 , written in C , named CP/M-8000 . These 16-bit versions of CP/M required application programs to be re-compiled for the new CPUs. Some programs written in assembly language could be automatically translated for a new processor. One tool for this was Digital Research's XLT86 , which translated .ASM source code for

8428-399: Was designed by David K. Brown. It incorporated the bank switching memory management of MP/M in a single-user single-task operating system compatible with CP/M 2.2 applications. CP/M 3 could therefore use more than 64 KB of memory on an 8080 or Z80 processor. The system could be configured to support date stamping of files. The operating system distribution software also included

8526-467: Was developed and released. ZCPR 3.3 no longer supported the 8080 series of microprocessors, and added the most features of any upgrade in the ZCPR line. ZCPR 3.3 also included a full complement of utilities with considerably extended capabilities. While enthusiastically supported by the CP/M user base of the time, ZCPR alone was insufficient to slow the demise of CP/M. A minimal 8-bit CP/M system would contain

8624-512: Was eventually displaced by DOS following the 1981 introduction of the IBM PC . Gary Kildall originally developed CP/M during 1974, as an operating system to run on an Intel Intellec-8 development system, equipped with a Shugart Associates 8-inch floppy-disk drive interfaced via a custom floppy-disk controller . It was written in Kildall's own PL/M ( Programming Language for Microcomputers ). Various aspects of CP/M were influenced by

8722-671: Was headquartered in San Diego , California with facilities located in Tijuana , Mexico. Many of Sanyo's television sets offer MHL compatibility along with Roku -ready branding via HDMI , meaning the TVs are compatible with Roku's MHL-specific streaming stick. Sometimes included with purchase, such as with the Sanyo FVF5044, this stick enables video streaming and other online functions as an affordable alternative to certain smart TVs;

8820-426: Was initially written by a group of computer hobbyists who called themselves "The CCP Group". They were Frank Wancho, Keith Petersen (the archivist behind Simtel at the time), Ron Fowler, Charlie Strom, Bob Mathias, and Richard Conn. Richard was, in fact, the driving force in this group (all of whom maintained contact through email). ZCPR1 was released on a disk put out by SIG/M (Special Interest Group/Microcomputers),

8918-489: Was instrumental at Sanyo in promoting Quadraphonic sound audio equipment for the American market, producing 4-channel audio equipment in both discrete and matrix formats. He said "we make all kinds of quadrasonic equipment because this is the business we're in... let the consumer buy the kind of software he prefers and we'll provide him the hardware to play it on". Sanyo realized tremendous growth during Ladd's tenure in

9016-550: Was lent an unused Matsushita plant in 1947 and used it to make bicycle generator lamps. Sanyo was incorporated in 1949; it made Japan's first plastic radio in 1952 and Japan's first pulsator-type washing machine in 1954. The company's name means three oceans in Japanese , referring to the founder's ambition to sell their products worldwide, across the Atlantic , Pacific , and Indian oceans. In 1969, Howard Ladd became

9114-483: Was married to one of Toshio's sisters. During his tenure at the company, he became an expert salesman, convincing wary resalers of the quality of Matsushita 's electric products, which were from Osaka, in an era where most electric goods in Japan were made in Tokyo. After serving in the Japanese military, Iue came back to Japan and became Konosuke's brother-in-law once again when he married Mumeno Matsushita. Iue then took

9212-514: Was probably the Amstrad PCW . In the UK, CP/M was also available on Research Machines educational computers (with the CP/M source code published as an educational resource), and for the BBC Micro when equipped with a Z80 co-processor. Furthermore, it was available for the Amstrad CPC series, the Commodore 128 , TRS-80 , and later models of the ZX Spectrum . CP/M 3 was also used on

9310-625: Was summoned to the office of the president of Sumitomo Bank after an ill-timed loan to acquire shares in Matsushita, which had become close to worthless after Japan's defeat. The bank president forgave Iue's debt, and knowing his prior talent working at Matsushita, offered him starting capital for a new business. Konosuke Matsushita would lend Iue an unused plant in Hyogo Prefecture , where he followed in his brother-in-law's footsteps by initially making bicycle lamps and captured 60% of

9408-465: Was the project manager for the evolving CP/M-86 line of operating systems. At this point, the original 8-bit CP/M became known by the retronym CP/M-80 to avoid confusion. CP/M-86 was expected to be the standard operating system of the new IBM PCs , but DRI and IBM were unable to negotiate development and licensing terms. IBM turned to Microsoft instead, and Microsoft delivered PC DOS based on 86-DOS . Although CP/M-86 became an option for

9506-672: Was transferred to the FDK Corporation. Sanyo supplies NiMh batteries to Honda , Ford , Volkswagen and PSA Peugeot Citroen . Sanyo is developing NiMH batteries for hybrid electric vehicles with the Volkswagen group, while their lithium-ion batteries for plug-in HEV will also be housed in Suzuki fleet vehicles. Sanyo planned to raise monthly production of NiMH batteries for hybrid vehicles from 1 million units to up to 2.5 million by

9604-422: Was written for CP/M than for operating systems that ran on only one brand of hardware. One restriction on portability was that certain programs used the extended instruction set of the Z80 processor and would not operate on an 8080 or 8085 processor. Another was graphics routines, especially in games and graphics programs, which were generally machine-specific as they used direct hardware access for speed, bypassing
