Definicon DSI-020 software?

I’ve recently come into a Definicon DSI-020 coprocessor card, and would like the software that goes with it. Does anyone know where to find it? There’s a zip file that claims to be the DSI-020 software, but it’s actually the DSI-32 software: The DSI-32 is an NS32032 coprocessor card, while the D

sorry, the technical manual actually, which has an architecture *chapter* http://www.bitsavers.org/pdf/dec/vax/650/ The idea, eventually, is that I will publish my notes so that you wouldn't need the logic analyzer, at least for the 8MB board. I just had it hooked up, so I demoed it. The notes wil

That is really interesting, sadly I don't have quite as much gear as you, I only have a basic logic analyser, but I am not currently trying to fix a MS650 memory board. You mentioned a KA650 architecture manual and you had a PDF of it in the video. I couldn't find it on Manx? Where can I find it

I finally got around to reading that note. My principal reponse is that it got so far down into details that I couldn't see the larger picture any more. Going back to the original IBM 801 work, the RISC concept is very simple: to make the overall system as fast as possible; it did this by making
