It was code named "Pismo" after the City of Pismo Beach, California . For this generation Apple dropped "G3" from the name. The original Pismo was rumored to be a latchless design, akin to the iBook , which is similar in specification. Apple settled on fitting

380-569: A Kanga to continue using their interchangeable expansion bay modules, batteries, and other peripherals from the Powerbook 190, 5300 and 3400 models. The Kanga was also notably smaller in depth and width than the subsequent Wallstreet Powerbooks, and the Kanga remained the smallest-when-open G3 laptop until the debut of the Apple iBook some years later. The second generation of PowerBook G3s, now called

456-540: A L2 cache that may have a capacity of 128  MB , and more powerful branch and load/store units that had more buffers, the 620 was very powerful. The branch history table was also larger and could dispatch more instructions so that the processor can handle out-of-order execution more efficiently than the 604. The floating-point unit was also enhanced compared to the 604. With a faster fetch cycle and support for several key instructions in hardware (like sqrt) made it, combined with faster and wider data buses, more efficient than

532-629: A bridge chip). The bus later evolved into the GX bus of the POWER4 , and later GX+ and GX++ in POWER5 and POWER6 respectively. The GX bus is also used in IBM's z10 and z196 System z mainframes. The PowerPC 602 was a stripped-down version of PowerPC 603, specially made for game consoles by Motorola and IBM, introduced in February 1995. It has smaller L1 caches (4 KB instruction and 4 KB data),

608-504: A die measuring 74 mm . The 601+ design was remapped from CMOS-4s to CMOS-5x by an IBM-only team. To avoid time-to-market delays from design tool changes and commonizing fab groundrules, both the 601 and 601+ were designed with IBM EDA tools on IBM systems and were fabricated in IBM-only facilities. The PowerPC 603 was the first processor implementing the complete 32-bit PowerPC Architecture as specified. Introduced in 1994, it

988-445: A lower energy consumption. The die was 47 mm small manufactured on a 0.25 μm CMOS process with five levels of interconnect, and drew 6 W at 250 MHz. It operated at speeds between 250 and 400 MHz and supported a memory bus up to 100 MHz. While Apple dropped the 604ev in 1998 in favor for the PowerPC 750 , IBM kept using it in entry-level models of its RS/6000 computers for several years. The PowerPC 620

1064-486: A single-precision floating-point unit and a scaled back branch prediction unit. It was offered at speeds ranging from 50 to 80 MHz, and drew 1.2 W at 66 MHz. It consisted of 1 million transistors and it was 50 mm large manufactured in a 0.5 μm, CMOS process with four levels of interconnect. 3DO developed the M2 game console that used two PowerPC 602, but it was never marketed. On October 21, 1996,

1140-644: A variety of RS/6000 workstations and SMP servers from IBM and Groupe Bull . IBM was the sole manufacturer of the 601 and 601+ microprocessors in its Burlington, Vermont and East Fishkill, New York production facilities. The 601 used the IBM CMOS-4s process and the 601+ used the IBM CMOS-5x process. An extremely small number of these 601 and 601+ processors were relabeled with Motorola logos and part numbers and distributed through Motorola. These facts are somewhat obscured given there are various pictures of

1216-476: A variety of design flaws, some of them severe, related to other aspects of the computers' design, including networking performance and stability, bus problems (width, speed, contention, and complexity), ROM bugs, and hard disk performance. None of the problems of the 5200 line, aside from 68K emulation performance, were inherently due to the 603. Rather, the processor was retrofitted to be used with 68K motherboards and other obsolete parts. The site Low End Mac rates

1292-405: Is a 32- or 64-bit 60x bus that operates at clock rates up to 50 MHz. The PowerPC 604 contains 3.6 million transistors and was fabricated by IBM and Motorola with a 0.5 μm CMOS process with four levels of interconnect. The die measured 12.4 mm by 15.8 mm (196 mm ) and drew 14-17 W at 133 MHz. It operated at speeds between 100 and 180 MHz. The PowerPC 604e

1444-605: Is sometimes called PowerPC 603ev . The 603e and 603ev have 2.6 million transistors each and are 98 mm and 78 mm large respectively. The 603ev draws a maximum of 6 W at 300 MHz. The PowerPC 603e was the first mainstream desktop processor to reach 300 MHz, as used in the Power Macintosh 6500 . The 603e was also used in accelerator cards from Phase5 for the Amiga line of computers, with CPUs ranging in speeds from 160 to 240 MHz. The PowerPC 603e

1520-536: Is still sold today by IBM and Freescale, and others like Atmel and Honeywell who makes the radiation hardened variant RHPPC . The PowerPC 603e was also the heart of the BeBox from Be Inc. The BeBox is notable since it is a multiprocessing system, something the 603 wasn't designed for. IBM also used PowerPC 603e processors in the IBM ThinkPad 800 series . In certain digital oscilloscope series, LeCroy used

1596-506: Is the only G3 system that is not officially compatible with Mac OS X (though various methods not sanctioned by Apple can be used to install OS X). The Kanga was on the market for less than 5 months, and is largely regarded as a stopgap system that allowed Apple to ship G3 PowerBooks sooner, while Apple prepared its more revolutionary PowerBook G3 Series. As a result, the Kanga has the dubious distinction of being Apple's most quickly deprecated PowerBook. Nevertheless, many people chose to purchase

1672-451: The Crusoe processor. With progress having been demonstrated in the development of dynamic translation software, such as Digital's FX!32 technology, skepticism was expressed about dedicating hardware resources to running foreign binaries when such resources could be used to improve native performance instead, this also benefiting the performance of translated binaries. "PowerPC 625" was

1748-526: The fabless semiconductor company Quantum Effect Devices (QED) announced a PowerPC 603-compatible processor named " PowerPC 603q " at the Microprocessor Forum . Despite its name, it did not have anything in common with any other 603. It was a from the ground up implementation of the 32-bit PowerPC architecture targeted at the high-end embedded market developed over two years. As such, it was small, simple, energy efficient, but powerful; equaling

1824-463: The "Motorola MPC601", particularly one specific case of masterful Motorola marketing where the 601 was named one of Time Magazine ' s 1994 "Products of the Year" with a Motorola marking. An updated version, the PowerPC 601v or PowerPC 601+ , operating at 90 to 120 MHz was introduced in 1994. It was fabricated in a newer 0.5 μm CMOS process with four levels of interconnect, resulting in

1900-409: The 13.3" and 14.1" models were equipped with 4 MB VRAM allowing for 'millions of colors' at maximum resolution (1024×768 for both; the 13.3" having a higher pixel density). The 13.3" display came with a quick-to-fail ribbon cable that was produced too short, leading to a swath of warranty repairs that led Apple to remove the 13.3" model from the lineup after the initial production run. The Wallstreet

1976-547: The 333 MHz model was left without (except for the PC card one used by Wallstreet). Further DVD playback optimizations enabled both models to play back DVDs without use of hardware assistance. This model introduced USB ports to the PowerBook line while retaining SCSI support and eliminating ADB entirely (although the keyboard and touchpad still used an ADB interface internally). Graphics were provided by an ATi Rage LT Pro chipset on

2052-511: The 4 MB on the faster 14.1" models. The 13.3" display was removed from the line, owing to both the falling production costs of the larger TFT and the near-guaranteed failure of the 13.3" models' ribbon cable through the hinge; it was produced slightly too short, and many failed soon after purchase. Processor speeds were bumped on the faster two models, resulting in 233 MHz, 266 MHz, and 300 MHz models. The case has two docking bays, one on each side. The left-hand bay can accommodate

2128-480: The 88110 bus as the basis for the 60x bus helped schedules in a number of ways. It helped the Apple Power Macintosh team by reducing the amount of redesign of their support ASICs and it reduced the amount of time required for the processor designers and architects to propose, document, negotiate, and close a new bus interface (successfully avoiding the "Bus Wars" expected by the 601 management team if

2204-448: The 88110 bus or the previous RSC buses hadn't been adopted). Worthy to note is that accepting the 88110 bus for the benefit of Apple's efforts and the alliance was at the expense of the first IBM RS/6000 system design team's efforts who had their support ASICs already implemented around the RSC's totally different bus structure. This 60x bus later became a fairly long lived basic interface for

2280-450: The Apple system design team was familiar with the I/O bus structure from Motorola's 88110 and this I/O bus implementation was well defined and documented, the 601 team adopted the bus technology to improve time to market. The bus was renamed the 60x bus once implemented on the 601. These Motorola (and a small number of Apple) designers joined over 120 IBM designers in creating the 601. Using

2432-567: The FPU in the 604. The system bus was a wider and faster 128-bit memory bus called the 6XX bus . It was designed to be a system bus for multiprocessor systems where processors, caches, memory and I/O was to be connected, assisted by a system control chip. It supports both 32- and 64-bit PowerPC processors, memory addresses larger than 32 bits, and NUMA environments. It was also used in POWER3, RS64 and 601, as well as 604-based RS/6000 systems (with

2508-530: The Lombard were updated to an AGP -connected ATi Rage Mobility 128, though the video memory was kept at 8 MB, and could not be upgraded, and the screen's resolution was the same as well. A 6× DVD-ROM drive became standard. It was also the first PowerBook with AirPort networking as an official option (although it could be added to the earlier models via various third-party CardBus cards). The Pismo can be upgraded with additional RAM (officially 512 MB with then-available RAM, but it accepts 1 gigabyte ) and

Mac OS 8.6–10.3.9 are supported by Apple, but 10.4 is not, although OS X will not install (except for 10.0) if both RAM slots are not occupied with identical size RAM. The use of XPostFacto 4 enables users to upgrade to Tiger, and it runs quite well for an unsupported machine. More RAM (up to 512 MB ), a greater hard drive (up to 128 GB), and CPU upgrades (up to

2660-524: The Performa 5200 as the worst Mac of all-time. The 603 found widespread use in different embedded appliances. The performance issues of the 603 were addressed in the PowerPC 603e . The L1 cache was enlarged and enhanced to 16 KB four-way set-associative data and instruction caches. The clock speed of the processors was doubled too, reaching 200 MHz. Shrinking the fabrication process to 350 nm allowed for speeds of up to 300 MHz. This part

The Pismo was available at CPU speeds of 400 MHz or 500 MHz, with a front side bus speed of 100 MHz (one-third swifter than the Lombard's front side bus); it also implemented a unified motherboard architecture, and replaced SCSI with the newer FireWire interface (IEEE-1394). The PCI graphics used on

2812-538: The PowerBook G3 Series, was introduced in May 1998. The machine was completely redesigned with a new case that was lighter and more rounded than the previous PowerBook G3; however, it was still an Old World ROM Macintosh. The new PowerBooks, code-named Wallstreet, came in three screen sizes: a 12" passive matrix LCD, a 13.3-inch TFT LCD, and a 14.1-inch TFT LCD. The 12.1" models had 2 MB VRAM onboard, while

2888-561: The PowerBook series. The PDQ series was entirely produced in Taiwan, and the machine's manufacture labels (showing production in Ireland or Taiwan) on the underside of the machines can be used to identify between otherwise nearly identical Wallstreet and PDQ series for collectors and enthusiasts. The 12.1" and 13.3" Wallstreet I and PDQ series shared a more curved top case at all corners; the lid and its corners were flattened and squared off for

New PowerPC changes, leveraging the basic RSC structure was very beneficial to reducing the uncertainty in chip area/floorplanning and timing analysis/tuning. Worth noting is that the 601 not only implemented substantial new key functions such as SMP, but it also acted as a bridge between the POWER and the future PowerPC processors to assist IBM and software developers in their transitions to PowerPC. From start of design to tape-out of

3192-576: The design leveraged a number of key technologies and project management strategies. The 601 team leveraged much of the basic structure and portions of the IBM RISC Single Chip (RSC) processor, but also included support for the vast majority of the new PowerPC instructions not in the POWER instruction set . While nearly every portion of the RSC design was modified, and many design blocks were substantially modified or completely redesigned given

3268-602: The designation MPC82xx, and come in a variety of configurations reaching 450 MHz. The G2 name is also used as a retronym for the 603e and 604 processors to align with the G3, G4, and the G5. Freescale has enhanced the 603e core, calling it e300 , in the PowerQUICC II Pro embedded processors. Larger 32/32 KB L1 caches and other performance enhancing measures were added. Freescale's PowerQUICC II Pro SoC processors bear

3344-552: The designation MPC83xx, and come in a variety of configurations reaching speeds up to 667 MHz. The e300 is also the core of the MPC5200B SoC processor that is used in the small EFIKA computer. The PowerPC 604 was introduced in December 1994 alongside the 603 and was designed as a high-performance chip for workstations and entry-level servers and as such had support for symmetric multiprocessing in hardware. The 604

3420-497: The die had an area of 311 mm . It operated at clock rates between 120 and 150 MHz, and drew 30 W at 133 MHz. A later model was built using a 0.35 μm process, enabling it to reach 200 MHz. The 620 was similar to the 604. It has a five-stage pipeline, same support for symmetric multiprocessing and the same number of execution units; a load/store unit, a branch unit, an FPU, and three integer units. With larger 32 KB instruction and data caches, support for

3496-501: The early name for the Apache series 64-bit PowerPC processors, designed by IBM based on the "Amazon" PowerPC-AS instruction set. They were later renamed " RS64 ". The designation "PowerPC 625" was never used for the final processors. "PowerPC 630" was the early name for the high end 64-bit PowerPC processor, designed by IBM to unify the POWER and PowerPC instruction sets. It was later renamed " POWER3 ", probably to distinguish it from

3572-452: The first 601 prototype was just 12 months in order to push hard to establish PowerPC on the market early. In order to help the effort to rapidly incorporate the 88110 bus architecture to the 601 for the benefit of the alliance and its customers, Motorola management provided not only the 88110 bus architecture specifications, but also a handful of 88110 bus-literate designers to help with the 60x bus logic implementation and verification. Given

3648-609: The first Apple Power Macintoshes on March 14, 1994. The 601 was the first advanced single-chip implementation of the POWER/PowerPC architecture designed on a crash schedule to establish PowerPC in the marketplace and cement the AIM alliance. In order to achieve an extremely aggressive schedule while including substantially new functionality (such as substantial performance enhancements, new instructions and importantly POWER/PowerPC's first symmetric multiprocessing (SMP) implementation)

3724-433: The fourth generation PowerPC even though the architectural differences between "G3" and "G4" was small. There are hardly any sources confirming any of this though and it might be pure speculation, or a reference to a completely different processor. The " PowerPC 615 " is a PowerPC processor announced by IBM in 1994, but which never reached mass production . Its main feature was to incorporate an x86 core on die, thus making

3800-406: The larger LCD of the 14.1" model resulting in a bulkier appearance. Many press releases and visual media at the time relied on the more 'attractive' curvature of the case on those smaller-display models, regardless of the 14.1" model's superior and more upmarket display. The third generation of PowerBook G3 (Lombard) was introduced in May 1999. It was much slimmer and lighter than its predecessor and

3876-475: The logic boards. This encouraged the aftermarket, including Sonnet, Powerlogix, Wegener Media, and others, to offer G3 CPU upgrades across various series. In some instances, they even provided G4 upgrades, allowing these machines to rival or exceed the performance of Apple's contemporary 'G4 Titanium' PowerBooks of that era. The first Macintosh PowerBook G3, code-named "Kanga", was introduced in November 1997. At

The chip was designed to suit a wide variety of applications and had support for external L2 cache and symmetric multiprocessing . It had four functional units, including a floating-point unit , an integer unit , a branch unit and a sequencer unit. The processor also included a memory management unit . The integer pipeline

4028-496: The more expensive 603e while drawing less power. It had an in-order, five-stage pipeline with a single integer unit, a double-precision floating-point unit (FPU) and separate 16 KB instruction and 8 KB data caches. While the integer unit was a brand new design, the FPU was derived from the R4600 to save time. It was 69 mm small using a 0.5 μm fabrication process and drew just 1.2 W at 120 MHz. The 603q

4104-420: The motherboard included doubling the onboard RAM from 16  MB to 32 MB, and a faster version of the on-board Chips and Technologies graphics controller. The G3 made the Kanga more than twice as fast as a 3400c, and the improved graphics controller allowed it to refresh the screen 74 percent faster. This first PowerBook G3 shipped with a 250 MHz G3 processor and a 12.1-inch TFT SVGA LCD . It

4180-684: The other two in the lineup. The 250 MHz and 292 MHz models shipped with 1 MB of cache. Because of this large cache, as well as the swifter system bus, the Wallstreets were known to suffer from some heat issues. Many of the problems of the Wallstreet PowerBook G3s were fixed in the next revision, the Wallstreet II. The WallStreet I was the last PowerBook assembled by Apple in Cork, Ireland . The Wallstreet design

4256-478: The processor able to natively process both PowerPC and x86 instructions. An operating system running on PowerPC 615 could either choose to execute 32-bit or 64-bit PowerPC instructions, 32-bit x86 instructions or a mix of three. Mixing instructions would involve a context switch in the CPU with a small overhead. The only operating systems that supported the 615 were Minix and a special development version of OS/2 . It

4332-547: The smaller processor caches. As a result, Apple chose to only use the 603 in its low-cost desktop Performa line. This caused the delay of the Apple PowerBook 5300 and PowerBook Duo 2300 , as Apple chose to wait for a processor revision. Apple's use of the 603 in the Performa 5200 line led to the processor getting a poor reputation. Aside from the issue of 68K emulation performance, the Performa machines shipped with

4408-625: The time of its introduction, the PowerBook G3 was advertised as the fastest notebook computer available (a title formerly held by its predecessor, the 240 MHz PPC-603ev -based PowerBook 3400c). This model was based on the PowerBook 3400c , and was unofficially known as the PowerBook 3500. It used the same case as the 3400c, and a very similar motherboard. The motherboard was upclocked from 40 MHz to 50 MHz, resulting in some incompatibility with older 3400 RAM modules. Other changes to

4484-474: The use of a hardware decoder built into a CardBus (PCMCIA) card. The PowerBook G3 Series was Apple's first notebook offering that matched the build-to-order customization of the Power Mac G3 desktop line. It was discontinued in May 1999. It is the last Apple computer ever to bear the rainbow-colored Apple logo, and the last Mac to support Apple's SuperDrive . It was also the last Old World ROM model in

4560-501: The world for its entire production run. The PowerBook G3 was succeeded by the PowerBook G4 . The G3 was the first black Apple laptop, and was succeeded in this by the black MacBook in 2006. Previous PowerBooks were dark gray. The Wallstreet, Lombard, and Pismo models were praised for their straightforward upgrade options, not only for accessible drives and memory but also for their CPU daughtercards that could be detached from

4636-407: Was 121 mm large and contained 2.8 million transistors. The 601 has a 32 KB unified L1 cache , a capacity that was considered large at the time for an on-chip cache. Thanks partly to the large cache it was considered a high performance processor in its segment, outperforming the competing Intel Pentium . The PowerPC 601 was used in the first Power Macintosh computers from Apple , and in

The PowerPC 604ev , 604r or "Mach 5" was introduced in August 1997 and was essentially a 604e fabricated by IBM and Motorola with a newer process, reaching higher speeds with

4788-401: Was 330 mm large and manufactured by IBM on a 0.35 μm process. It was pin compatible with Intel 's Pentium processors and comparable in speed. The processor was introduced only as a prototype and the program was killed in part by the fact that Microsoft never supported the processor. Engineers working on the PowerPC 615 would later find their way to Transmeta , where they worked on

4864-492: Was an advanced design for its day, being one of the first microprocessors to offer dual issue (up to three with branch folding) and out-of-order execution combined with low power consumption of 2.2 W and a small die of 85 mm . It was designed to be a low cost, low power processor for portable applications. One of the main features was power saving functions (doze, nap and sleep mode) that could dramatically reduce power requirements, drawing only 2 mW in sleep mode. The 603 has

4940-434: Was designed for Motorola, but they withdrew from the contract before the 603q went into full production. As a result, the 603q was canceled as QED could not continue to market the processor since they lacked a PowerPC license of their own. "PowerPC 613" seems to be a name Motorola had given a third generation PowerPC. It supposedly was renamed " PowerPC 750 " in response to Exponential Technology 's x704 processor that

5016-453: Was designed to outgun the 604 by a wide margin. There are hardly any sources confirming any of this though and it might be pure speculation, or a reference to a completely different processor. Similar to PowerPC 613, the "PowerPC 614" might have been a name given by Motorola to a third generation PowerPC, and later renamed by the same reason as 613. It's been suggested that the part was renamed " PowerPC 7400 ", and Motorola even bumped it to

5092-533: Was four stages long, the branch pipeline two stages long, the memory pipeline five stages long, and the floating-point pipeline six stages long. First launched in IBM systems in the fall of 1993, it was marketed by IBM as the PPC601 and by Motorola as the MPC601. It operated at speeds ranging from 50 to 80 MHz. It was fabricated using a 0.6 μm CMOS process with four levels of aluminum interconnect . The die

5168-455: Was introduced in July 1996 and added a condition register unit and separate 32 KB data and instruction L1 caches among other changes to its memory subsystem and branch prediction unit, resulting in a 25% performance increase compared to its predecessor. It had 5.1 million transistors and was manufactured by IBM and Motorola on a 0.35 μm CMOS process with five levels of interconnect. The die

5244-404: Was the first New World ROM PowerBook. It had longer battery life, and as with the Wallstreet II the user could double the duration to 10 hours by substituting a second battery for the optical drive in the expansion bay. The keyboard was also improved and now featured translucent bronze-tinted plastics, which is the origin of the "bronze keyboard" nickname. It was also the first Apple laptop to have

5320-437: Was the first PowerBook to use industry-standard ATA optical drives. This change meant that CD and DVD recorders designed for Wintel machines could more easily be used in this computer, often at a price far less than those manufactured by Apple. It also came in three CPU speeds: 233 MHz, 250 MHz, and 292 MHz. The 233 MHz model was sometimes nicknamed Mainstreet, as it lacked L2 cache, making it far slower than

5396-432: Was the first implementation of the entire 64-bit PowerPC architecture. It was a second generation PowerPC alongside the 603 and 604, but geared towards the high-end workstation and server market. It was powerful on paper and was initially supposed to be launched alongside its brethren but it was delayed until 1997. When it did arrive, the performance was comparably poor and the considerably cheaper 604e surpassed it. The 620

5472-731: Was the last of the G3 line. It was succeeded by the PowerBook G4 Titanium models. According to Apple, all of these models are obsolete. The PowerBook G3 was featured in many facets of popular culture from the late 1990s to the mid 2000s, including You've Got Mail , NewsRadio , Curb Your Enthusiasm , Austin Powers: The Spy Who Shagged Me , House on Haunted Hill , Mission: Impossible , Disney's The Kid , Dark Angel , What Women Want , The West Wing , Friends , The Lone Gunmen , The Core , Duplex , Saw , Sex and

5548-441: Was therefore never produced in large quantities and found very little use. The sole user of PowerPC 620 was Groupe Bull in its Escala UNIX machines, but they didn't deliver any large numbers. IBM, which intended to use it in workstations and servers, decided to wait for the even more powerful RS64 and POWER3 64-bit processors instead. The 620 was produced by Motorola in a 0.5 μm process. It had 6.9 million transistors and

5624-399: Was tough to find), or a second battery. Lombard and Pismo accept the same expansion bay devices. Versions of Mac OS from 9.0.2 through 10.4.11 are officially supported. For some time, G3 (750FX) CPU upgrades at speeds of up to 900 MHz and G4 (7410LE) upgrades up to 550 MHz were available. These upgrades are now out of production and must be purchased secondhand. The Pismo PowerBook

5700-420: Was updated in August 1998 (Wallstreet-II). It featured a 14.1-inch display on 266 MHz and 300 MHz models. The 233 MHz machine was now equipped with a vastly improved TFT panel (compared to the passive matrix of the 12.1" Wallstreet I series), as well as a 512 KB backside cache allowing for far superior performance at the same 233 MHz, though it was equipped with 2 MB onboard VRAM compared to

5776-786: Was used extensively in Apple 's high-end systems and was also used in Macintosh clones , IBM's low-end RS/6000 servers and workstations, Amiga accelerator boards, and as an embedded CPU for telecom applications. The 604 is a superscalar processor capable of issuing four instructions simultaneously. The 604 has a six-stage pipeline and six execution units that can work in parallel, finishing up to six instructions every cycle. Two simple and one complex integer units , one floating-point unit , one branch-processing unit managing out-of-order execution and one load/store unit. It has separate 16 KB data and instruction L1 caches. The external interface
