Mac IIvx

The Mac IIvx 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 IIvx ran a 32 MHz CPU on a 16 MHz bus. This gave it slower performance than the IIci, which was still available (stock IIci tests 30% faster than IIvx; adding 32 KB cache to the IIci bumps this to 60%).

Macintosh IIvxIn fact, the old 16 MHz Mac IIx outperformed the IIvx on some benchmarks! Needless to say, most serious Mac users chose the IIci over the IIvx.

The Mac IIvx and its near-twin, the Performa 600, were the first Macs available with a built-in CD-ROM drive and also the first Macs to use a metal case.

The floppy drive mounting sled used in the IIvi, IIvx, Centris 650, Quadra 650, and Power Mac 7100 can also be used for a hard drive if you no longer need the floppy drive.

Although it wasn’t officially discontinued until October 1993, with the introduction of the 25 MHz 68040-based Centris 650 in the same enclosure and at the same price just five months later, Apple slashed it’s base price from US$2,949 to US$1,899 overnight. Needless to say, a lot of recent IIvx buyers were none to happy with Apple over that.

The IIvx and Performa 600 easily merit the Road Apple designation.
