The PowerBook G3 series represents a pivotal line of portable Macintosh computers produced by Apple Computer from November 1997 to February 2001, distinguished by its use of the PowerPC G3 (PPC 740/750) processors.[5] This series succeeded the PowerBook 1400 and 2400 models, completing Apple's shift to the more efficient PowerPC architecture in laptops following the earlier phase-out of 68k-based systems.[2] At launch, the inaugural PowerBook G3 (codenamed Kanga) was positioned as the world's fastest notebook computer, leveraging the G3's architectural advantages to deliver superior performance in a portable form factor.[2] A core innovation of the series was the PowerPC G3 processor's backside Level 2 (L2) cache, which operated at full processor speed to minimize latency and boost overall efficiency compared to prior PowerPC iterations like the 603e.[2] The series featured hot-swappable modular bays for batteries and drives, allowing users to exchange components without shutting down the system.[3] Additionally, the design incorporated PC Card slots compatible with emerging wireless standards, making the PowerBooks "airport-ready" for add-on 802.11 cards ahead of Apple's AirPort rollout.[6] These features enhanced portability and usability, setting new benchmarks for professional mobile computing during the era. Spanning over three years, the PowerBook G3 bridged Apple's transitional period in portable hardware, paving the way for the PowerBook G4 series launched in early 2001 with its faster PowerPC 7450 processors.[5] The lineup's diverse configurations—from entry-level to high-end professional models—catered to a broad user base, including creative professionals and business users seeking reliable performance on the go.[3] Commercially, the PowerBook G3 contributed significantly to Apple's recovery amid late-1990s financial challenges, as sales of G3-based products, including the PowerBooks, helped drive the company back to profitability in its fiscal first quarter of 1998 with a net income of $47 million, reversing prior losses.[7] This momentum stabilized Apple's declining market share, which had fallen to around 3% by mid-1997, by reinvigorating interest in Macintosh hardware during a critical juncture.[8]Development and Release
The development of the PowerBook G3 series stemmed from the AIM alliance formed in 1991 between Apple, IBM, and Motorola to advance PowerPC processor technology, culminating in the third-generation PowerPC G3 (750) chip, whose design work began in the mid-1990s.[9] This collaboration enabled Apple to integrate the new processor into portable computing, with the initial model codenamed "Kanga" representing a rapid adaptation of the existing PowerBook 3400 chassis to accommodate the G3's architecture.[10] Engineers addressed key challenges in adapting the desktop-oriented G3 for mobile use, including enhanced power management to extend battery life and thermal solutions to handle clock speeds ranging from 250 MHz upward without excessive heat buildup in a compact form factor.[2] The PowerBook G3 was unveiled on November 10, 1997, by Steve Jobs, then serving as Apple's interim CEO, during a special event at the Flint Center in Cupertino, California, alongside the debut of the Power Macintosh G3 desktop line.[11] This announcement marked a pivotal moment in Apple's hardware strategy, emphasizing performance gains from the G3 processor, which offered up to twice the speed of prior PowerPC models at comparable power levels. First units of the Kanga model began shipping in late November 1997, positioning the series as Apple's flagship portable for professional users.[10] Apple priced the base Kanga configuration—a 250 MHz model with a 12.1-inch display, 32 MB RAM, and 5 GB hard drive—at $5,699, reflecting its premium status as a high-performance laptop targeted at business and creative professionals seeking superior processing power over competitors like Intel-based systems.[12][1] Manufacturing occurred at Apple's facilities in Sacramento, California, and Cork, Ireland, with additional assembly support in Singapore to meet global demand.[13]Model Lineup
Kanga (Macintosh PowerBook G3)
The Kanga, codenamed as such internally, marked the debut of the PowerBook G3 series when Apple released it in November 1997 as the first laptop powered by the PowerPC G3 processor family.[10] This model served as a prototype for the lineup, essentially updating the prior PowerBook 3400c with a faster 250 MHz PowerPC 750 (G3) processor and 512 KB level 2 cache while retaining much of the established chassis design to accelerate time to market during a challenging period for the company.[1] Its introduction just days before the first desktop G3 systems underscored Apple's push to integrate the new architecture across its portable lineup.[14] Physically, the Kanga featured a 12.1-inch active-matrix TFT display with 800x600 resolution and 16-bit color depth, supported by 2 MB of dedicated VRAM for external video output up to millions of colors.[1] The overall build measured 11.5 by 9.5 by 2.4 inches and weighed about 7.5 pounds, emphasizing portability for professionals despite its bulkier profile compared to later redesigns.[15] It included a tappable trackpad for input, along with a full keyboard, and supported modular expansion bays—one 5.25-inch hot-swappable bay defaulting to a 20x CD-ROM drive and a separate 3.5-inch floppy module.[14] The lithium-ion battery provided 2 to 4 hours of runtime and was the first in an Apple laptop to allow hot-swapping in the expansion bay configuration for extended use without full shutdown, aided by a small internal backup battery.[1] Connectivity on the Kanga reflected late-1990s standards, with an HDI-30 SCSI port, a single ADB port for peripherals like keyboards or mice, built-in 10BASE-T Ethernet, a 33.6 kbps modem, 1 Mbps IrDA, and two Type II PC Card slots (compatible with one Type III), but it omitted emerging interfaces like USB or FireWire.[16] Standard configurations started at 32 MB of soldered RAM (expandable to 160 MB via one slot), a 5 GB IDE hard drive, and pre-installed Mac OS 8.0, priced at $5,700 for the base model.[1] Higher-end options allowed RAM upgrades and larger drives, targeting business users seeking G3 performance in a familiar form.[14] As a short-lived prototype produced for only about five months, the Kanga bridged the gap to the more refined Wallstreet series, which introduced a slimmer design and additional speed variants.[14]Wallstreet Series
The Wallstreet series represented a significant refresh of the PowerBook G3 lineup in 1998, introducing enhanced performance and greater flexibility compared to the earlier Kanga model's fixed internal design. Released on May 6, 1998, the initial variants included configurations with a 233 MHz PowerPC 740 processor (no L2 cache) or 250 MHz and 292 MHz PowerPC 750 processors with 512 KB level 2 cache, marking a step up from the Kanga's 250 MHz processor while emphasizing portability and expandability.[17][18][19][20] A key innovation in the Wallstreet series was the modular drive bay system, allowing users to swap the 5.25-inch bay for a 20x CD-ROM drive, Iomega Zip drive, or other compatible modules without tools, enhancing adaptability for storage needs.[17][18] The chassis adopted a curvaceous black plastic exterior with subtle metallic accents for durability and aesthetics, weighing around 7.6 pounds and measuring 1.7 by 12.7 by 10.4 inches. Input was improved with a full-size keyboard including dedicated function keys and an inverted-T arrow cluster, paired with a trackpad for precise control. Display options expanded to include a new 13.3-inch TFT active-matrix screen at 1024x768 resolution alongside the existing 12.1-inch passive-matrix (800x600) and 14.1-inch active-matrix (1024x768) panels, all supporting 24-bit color and S-video output.[17][19][20] In November 1998, Apple updated the lineup with the PDQ ("Pretty Darn Quick") variant, featuring a faster 66 MHz system bus and processors up to 300 MHz on the PowerPC 750, with 512 KB or 1 MB L2 cache options for sustained performance gains—the 1 MB cache providing approximately a 20% performance improvement in tasks like application loading and multitasking due to faster data access.[21][22][17] Standard configurations offered 32 MB or 64 MB of RAM (expandable to 192 MB officially via two SO-DIMM slots) and hard drives from 2 GB to 8 GB, though 6 GB was common in mid-range models.[21][23] Pricing started at $2,299 for the base 233 MHz model with a 12.1-inch display and rose to $5,599 for high-end 292 MHz units with larger screens and storage, positioning the series as a premium portable workstation.[19][20]Lombard (Bronze Keyboard)
The Lombard, codenamed after the California mountain range, was introduced in May 1999 as the third iteration in the PowerBook G3 lineup, featuring updated aesthetics and connectivity options.[24] It succeeded the Wallstreet series with a redesigned chassis that was 20% slimmer and approximately two pounds lighter, weighing 5.9 pounds overall, while incorporating a distinctive bronze-tinted keyboard and palmrest for improved visibility in low-light conditions.[4] This model marked Apple's initial integration of USB ports into its professional laptops, aligning with emerging industry standards for peripheral connectivity. Available in two configurations, the base model featured a 333 MHz PowerPC 750 processor with 512 KB of level 2 cache, 64 MB of RAM (expandable to 384 MB officially), a 4 GB hard drive, and a 24x CD-ROM drive, priced at $2,499.[25] The higher-end variant upgraded to a 400 MHz PowerPC 750 processor with 1 MB of level 2 cache, 64 MB of RAM, a 6 GB hard drive, and a 2x DVD-ROM drive, starting at $3,499.[26] Both shared a 14.1-inch TFT active-matrix display supporting 1024x768 resolution at 24-bit color, 8 MB of dedicated video RAM, and a single Type II PC Card slot for expansion.[27] Connectivity emphasized a transitional approach to modern interfaces, including two USB 1.1 ports for devices like keyboards and mice, a 10/100 Base-T Ethernet port, a 56 kbps modem, and an HDI-30 SCSI connector for legacy peripherals, though it lacked FireWire.[25] Wi-Fi support was possible via third-party PC Card adapters, as the chassis included provisions for such cards without a dedicated internal slot.[28] The modular expansion bay allowed swapping between optical drives, a floppy drive, or a second battery for extended use. Battery life benefited from a 50 Wh lithium-ion pack, providing up to five hours of runtime on a full charge under typical conditions, extendable to nine or ten hours with a supplementary battery module in the expansion bay.[26] This improvement over prior models supported mobile productivity, though actual duration varied with usage and processor speed. The Lombard's USB adoption positioned it as a bridge to future connectivity, paving the way for the Pismo model's full FireWire implementation.[27]| Model | Processor | Base RAM | Base Storage | Optical Drive | Starting Price |
