Overview

The Mac IIvi was a slower version of the IIvx, running a 16 MHz 68030 on a 16 MHz bus. The IIvi was never sold in the United States. Unlike the IIvx, the IIvi cannot accept a level 2 (L2) cache, although it can accept an accelerator.

In terms of performance, it held its own against the crippled IIvx.
