Can I replace a KA630 with a KA650 in a MicroVAX II?
Yes. The KA630, KA650, and KA655 use the same cab kit. However the
KA650 and KA655 use MS650 memory. MS630 memory will not work with them.
Although it appears that DEC did not sell a MicroVAX III as a new
product, they offered a MicroVAX II to MicroVAX III upgrade that included
the KA650, MS650, and a new nameplate.
I've heard of the MicroVAX II/III being upgraded to the KA655 and then
being called a MicroVAX III+. I don't know whether DEC ever officially
offered that upgrade or referred to it by that name.
I've upgraded a VAXstation II/GPX to a KA655 with three 16MB MS650 cards
and have run NetBSD on it. I have not tried to install VMS.
