Poop. Ok, thanks for the info.
I really don't want to run an expansion chassis, but there are hardly
any Unibus slots in an 11/70. :-( I saw those grant cards and figured I
might get lucky.

Does anyone
know offhand if it's possible to use the "BCT" slot for an
RH70 in the PDP-11/70 backplane as a standard Unibus slot, for, say, an
RX211 or something like that? It would seem to be a normal Unibus slot,
Not even close. It uses many of the pins to pass signals to the other
modules of the RH70. Even the power supply pins don't match.
