I know there was the AT&T UNIX PC which was a 68010 + custom external MMU, but there was also a proprietry cpu version I ran into the trap of in a past life. The "UNIX PC" is the 7300, which is nearly identical to the 3B1. The 3B1 has a slightly larger top cover to accommodate a full-height hard drive, while the 7300 will only hold a half-height drive. They are otherwise identical, using 68010s. I'd sure like to know more about the "proprietary cpu" version you're talking about. -Dave -- Dave McGuire, AK4HZ New Kensington, PA
