Performa 600

The Performa 600 was an okay computer, but a big “Huh?” for Mac IIci users. Where the LC and LC II had been compromised by using a 32-bit processor on a 16-bit data bus, the Performa 600 ran a 32 MHz CPU on a 16 MHz bus. This gave it slower performance than the 25 MHz IIci, which was still available. In fact, the old 16 MHz Mac IIx outperformed the Performa 600 on some benchmarks!

Performa 600Worse yet, the Performa 600, doesn’t support a level 2 cache in the Processor Direct Slot, although it will accept accelerators.

Needless to say, most serious Mac users chose the IIci over the Performa 600.

The Performa 600 was the first Mac available with a built-in CD-ROM drive and also the first Mac to use a metal case.

The Performa 600 and its near-twin, the IIvx, easily merit the Road Apple designation.
