    JFYI:

    An intersting post by mr.neozeed about Definicon DSI-32:

    Here are some photos and related files http://ftp.berklix.org/~dlr/pd32/

    Who is interested in building a "Public Domain 32000" ISA board if it were produced in small hobbyist quantities?
    I would be interested... I just recently got a P3 board with ISA slots...

    I just built an ISA machine (again) and sure, I'd love some more vintage for my vintage!

    Hi

    I built the PD32 in KiCAD and it is basically ready to go. The PCB is done and trace routed and ready for ordering prototype PCBs.

    However Dave Rand is designing a new PD32+ based on NS32032 and modern components which made the vintage 1986 design OBE.

    Most likely this project will join the ranks of the walking dead.

    I was hoping it didn't just go and die... Although even in this day and age ISA machines are getting rare, even 32bit 3.3v PCI is getting harder to find.

    No, it didn't die but it did join the stable of walking dead projects. This project is essentially done and ready to go to PCBs prototype or production.

    However Dave Rand is working on the PD32+ which makes this board OBE. I helped Dave with PD32+ for a while and got it going in the right direction but Dave kind of went off on his own way and I really couldn't help much any more. We kept in contact for a while but I haven't heard from Dave recently so I am not sure if PD32+ is going to happen or not.

    If PD32+ doesn't happen for whatever reason, we can always revive PD32 or even pull the Bruce Culbertson project. Both are essentially complete and just waiting to be built but became OBE for one reason or another.

    I think, FPGA version is faster and more easy to run. This board
    http://cpu-ns32k.net/PC632M.html
    may be modifyed with 3.3/5V level shifter to attach DE0-nano to ISA bus.

    ns32k architecture may be used as a good "core" for "amateur" SoCs. There is a
    working GNU toolchain. AFAIK, the legal status is "abandonware" and NS
    permitted to use this architecture to Udo Moeller for M32632 project.

    Yes, I know, there are another 32-bit CPU implementations for FPGA,
    but to have yet another architecture is not so bad.

    I heard back from Dave Rand and he is planning to make some PD32+ prototype boards. Looking forward to those and hopefully a NS32K revival.

    This is an interesting thread and the 1987 PC Magazine article was an interesting read. I hadn't found that one yet. I've had one of the DSI-780's for 15+ years and in the past could find almost nothing about it. I believe I picked it up out of a parts box one day...I thought it interesting that it was an ISA board with serial ports and the Motorola 68k series chips on it.
