Here are the RX50 and TK50 versions of the MicroVAX II
customer
diagnostics:
Ooh, thank you! Thank you very much.
I used them when I added the MicroVAX II to Simh a few
years ago. I
had some problems running them but that was largely due to the fact I
didn't implement memory parity, serial port loopback and other
non-essential features. I guess you have these though if you are
able to pass all the startup diagnostics.
Yes; those are both things I simulate. (I also had to simulate the
instruction prefetch buffer; it turns out the KA630 ROM code depends on
being able to execute out of the prefetch buffer briefly.)
If it helps at all, my code is in the main Simh
repository:
Look for the vax630*.* files
I suspect my issue, whatever it is, is not KA630-specific, in which
case the KA630-specific files from SIMH won't help.
Still, it can hardly hurt to look.
Hmm, perhaps I could rip the emulation core out of SIMH and run it in
lock-step parallel with mine, to see where they diverge. I wonder how
hard that would be to do...if I can't find anything more promising I'll
have a look at it.
