Our R&D group has brought up Unix system V release 2 on an IBM PC-XT equivalent machine. This Unix is running on a PC-bus board made by Opus which uses a 32016 with 1MB of on-board memory & floating point hardware. The I/O is done by the 8088 via a special MS-DOS program and interprocessor interrupts. Indeed, vi, uucp, cc, et al run quite nicely, constrained by the seek time of the disk. We will soon change to a 30msec sort of disk and expect to see great improvements. We've moved on now into developing Unix and MS-DOS integrated packages, using off-the-shelf software wherever possible, eg, GKS for graphics. I'm interested in determining if there are others out there who are likewise working with 32 bit co-processors for the PC bus. We are assuredly NOT in pursuit of the 32016 microprocessor per se-- indeed a 68000 with a GOOD System V port would do well also.
