What's a super-12?
PDP-12 #10 is the super-12 (non-official term) that includes the floating
point option and an RK05. Interestingly, the RK05 is run from a standard
RK8E embedded in a chassis behind the -12s covers. There is a special
interface to get the PDP-12 (I forget if it is negibus or posibus) to
talk to the "processor-less PDP-8/e" within.
