PowerBook 5300

PowerBook laptop model

The PowerBook 5300 is the first generation of PowerBook laptops manufactured by Apple Computer to use the PowerPC processor. Released in August 1995, these PowerBooks were notable for being the first to feature hot-swappable expansion modules for a variety of different units such as Zip drives; PC Card slots as standard; and an infrared communication port.[1] In common with most preceding Macintosh portables, SCSI, Serial, and ADB ports were included as standard. An internal expansion slot was also available for installing a variety of modules including Ethernet and video cards to drive a second monitor in mirroring or dual-screen modes.

Although a significant advance over preceding portable Macs, the PowerBook 5300 suffered from a number of design faults and manufacturing problems that have led to it being cited as among the worst Apple products of all time.[2] Among other issues, it is one of the first laptops to suffer negative publicity from battery fires,[3] and features a hot-swappable drive bay with insufficient space for an internal CD-ROM drive.

Design

The PowerBook 5300 was designed during 1993 and 1994 under the codename M2. Compared with the preceding PowerBook 500 series, the 5300 was explicitly designed to be as small as possible (which precluded the use of a CD-ROM drive) and featured a more compact but less curvy design. Pop-out feet were used instead of the rotating rocker-style feet typical of earlier PowerBooks, and a slightly darker shade of grey was used for the plastic casing.[1] The PowerBook 190 and 190cs used an identical casing and shared many features and internal components, but used the older and slower Motorola 68LC040 processor instead, which could be upgraded to a full PPC processor by swapping the logic board.

Specifications

There are four models in the 5300 series, ranging from the low-end greyscale 5300 to the deluxe, high-resolution, TFT-equipped 5300ce:

Model Display CPU clock Standard RAM Retail price (US)
PowerBook 5300 640×480 pixel passive matrix greyscale LCD 100 MHz 8 MB $2,300
PowerBook 5300cs 10.4" 640×480 pixel passive matrix color LCD 8/16 MB $2,900
PowerBook 5300c 10.4" 640×480 pixel active matrix color LCD $3,900
PowerBook 5300ce 10.4" 800×600 pixel active matrix color LCD 117 MHz 32 MB[4] $6,800

Problems

For a variety of reasons, the PowerBook 5300 series has been viewed as a disappointment. Problems with cracked cases and overheating batteries prompted several recalls,[5] while some users were simply unimpressed with the specifications of the machine and its lackluster performance. Some systems, after heavy use, would develop hinge problems; cracking of the hinge covers, as well as internal ribbon cables wearing/tearing and causing the display to show vertical lines and occasionally black out completely. This problem existed on earlier Powerbook models as well, most notably the Powerbook 500 series (including 520, 540c and the black-cased, higher-spec Japan-only 550c)[2]

Lack of L2 cache

Although the PowerPC 603e processor built into the 5300 series was relatively fast for its time, because these machines lacked a Level 2 cache, real world performance was much less than the CPU frequency would suggest.[2]

Expansion bay options

The variety of expansion bay options available was wide, but because of the size and shape of the computer, fitting a CD-ROM drive into the available space wasn't possible.[1] Apple had a prototype CD-ROM module compatible with non-standard 80 mm disks that would have been used with the PowerBook 5300 series, but finished versions of this device were never released.[citation needed] Instead, it was planned that the 5300 series would use 3.5 inch magneto-optical drive modules initially, with the option of releasing a stretched version a year or two later that had space for a full-sized CD-ROM drive.[1]

Batteries

Two early production PowerBook 5300s caught fire, one at an Apple employee's house and another at the factory; it turned out that the Sony-manufactured lithium-ion batteries had overheated while recharging. Apple recalled the 5300s sold (around a hundred machines) and replaced the batteries on these and all subsequent 5300s with nickel metal hydride batteries that provided only about 70% the endurance.[6] At the time, the media viewed the problems with the PowerBook 5300 series as yet another example of Apple's decline.[5][7]

Legacy

Apple's next high-end series of portables, the PowerBook 3400 series introduced in February 1997, shared an almost identical form factor with the 5300, right down to being able to share many of the same hot-swappable expansion modules. However, the 3400 series were substantially different on the inside, featuring DMA and PCI architecture.[8] The first series of PowerBook G3 portables released in November 1997 were internally even more advanced, being built around the PowerPC G3 processor, though they still retained the basic PowerBook 5300 form factor. Apple did not introduce portables with an entirely new form factor until March 1998 with the release of the "Wallstreet" G3 PowerBooks.

Popular use in media

The 5300 is seen in several movies during the 1990s, including Liar Liar (1997), Free Willy 3: The Rescue (1997), Home Alone 3 (1997), The Saint (1997), Volcano (1997), My Best Friend's Wedding (1997), Jingle All the Way (1996), Ransom (1996) and Independence Day (1996).[9]
