Tips/leads for Nat Semi 32k system(s)?

Anybody have a suggestion for locating some kind of system based on the Nat Semi 32k family? At this stage the only preference I'd state is that it be a vaguely "open" platform (e.g. CompuPro's old 32016 S-100 board - I'd love a system built around one of these) or run some flavor of Unix (a la Nat Semi's Genix boxes or the Tektronix workstations). I followed Bruce Culbertson's 32016 design way back when, and of course Dave Rand et alia's pc532 board. I even have a 32k design kit from Nat Semi around here somewhere, but never got started on my ambitious plans of building something from Bruce's design. Suggestions or even just reminiscences would be welcome. Thanks, --Steve. -- Steve Jones smj(a)spamfree.crash.com Arlington, Mass. CRASH!!
