Macintosh Performa 600/600CD(1992)

Background

The IIvi was introduced in October 1992, and was exactly the same as the IIvx, but with a 16 MHz 68030 processor, and no FPU. It was priced several hundred dollars cheaper, and was discontinued just 4 months later, making it one of the shortest-lived Macs ever (often a sour point to IIvi owners). The Performas 600 and 600CD, which were released later in the consumer market, were based on the same logic board as the IIvi but shipped with the IIvx's 32MHz processor.
