I suspect Kenn Humborg is correct in thinking that these registers
control onboard logic and have nothing to do with CPU-internal
registers in the architecture sense, the sense of what MFPR and MTPR
access.

Um, no.  Quite aside from being documented as different, being a single
CVAX chip (which the KA620 isn't), and not being a Qbus card (which the
KA620 is), we know that it doesn't use MTPR/MFPR console access,
whereas the KA620 definitely does.  (Or, at least, the KA620s I worked
with back in the 1980s sure did! :-)
