No non-disclosure agreement was signed by any of the people that I know of, so I'll divulge what was said: Basically, they used the PC as an I/O processor. The 8088 handles disk I/O to the 802 system through a shared-memory buffer. Even with double-copy (disk to 8088 (DMA), 8088 to 802 memory, 802 to final resting place), the 8088 was not the bottle neck. they used an expansion box with multi-megabytes in it. They also had a graphics board for the thing. The 802 is about 1 -> 2 MIPS if I recall correctly. They had UNIX 4.2BSD up and running a year ago. At that time, they said that they weren't going to market the box (but then again, see PC Week from sometime in late july to early august -- rumors about an 802 based system). that's basically all they told us, but yes, some prototype did exist. dirk grunwald grunwald@uiuc.arpa
