Full Specifications

Released eight months after the original LC III and running at 8 MHz faster, the LC III+ didn't exactly do much to push the LC series along.


Following on from the LC and LC II, the LC III had done much to repair the tarnished image of the LC series. While the first two machines had been crippled by running their 32-bit 68030 CPU on a 16-bit bus, the LC III had finally got it right and really unleashed the potential of the low profile machine. Running at 25 MHz it might not exactly have been a speed demon but it did just about everything that users could ask of it.

Eight months after the release of the LC III, Apple decided that the time was right for the next installment in the LC series: the LC III+. Having made such massive improvements since the LC II, users were keen to see what the new LC would be capable of and what would be on offer. A speed bump (up to 33 MHz from 25 MHz) was never something to be sniffed at and... Actually, there wasn't an 'and' as, the speed bump aside, the LC III and LC III+ were identical under the hood.

The "+" was never used in the name of the product on the machine itself. Instead, Apple used a new top case design for the LC III+. This design was also used by the LC 475 and eliminated the Snow White-style groove. The name "Macintosh" was screened to the case, but model identification badges became stickers, presumably in an effort to shave costs since, aside from the sticker, the lid could be used on any other machine with the same form factor. The new case also modified the floppy drive slot to accommodate the newer auto-inject drive (another identifying feature of the LC III+).

Apple couldn't have expected users to pay extra for just a straight speed bump; especially when the LC III could actually run at 33 MHz with just a small motherboard mod. Luckily, they kept the price the same. This in itself raised the question: Why keep selling the slower LC III at the same price as the faster LC III+? More importantly, who on Earth would pay the same price for the slower version?
