Somebody gave me a KA-650, and I seem to recall I was 
running 4.7 on my home system.  I seem to recall that when I 
plugged the KA-650 in, it complained about something like 
the machine check handler did not support the KA-650.  Thus 
was all QUITE a number of years ago, so I could be wrong 
about the specifics.  Anyway, it seemed the choice was to 
run 5.1 with the 650, and have to deal with the license 
issues, or just keep running 4.7 with  no license on the 
KA-630, which is what I did.

I think VMS 4.7 would let the system manager do stuff on it, 
but would not let general users log on, with the 650.
