I don't
think that The KA630 code will work, (ok, maybe for the
loader) since the KA630 is using standard SLUs like the PDP11s.
I'm not sure what "standard SLUs" means across different architectures
and buses and such. The standard PDP-11 SLU, to the extent that there
is such a thing and to the extent that the info I've found is accurate,
is a subset of the VAX console: the status bits that both machines have
have the same values in their registers, and the VAX MTPR/MFPR
registers correspond 1:1 to the PDP-11 SLU registers (the PR numbers
are even in the same order as the PDP-11 addresses). So if there's a
chip designed for a PDP-11 SLU, it may well be what the KA620 and/or
KA630 uses.
