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.)

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.
