Here's my take on the issue of not being able to use standard drivers and
receivers for UNIBUS and Q-bus. Aren't both of these buses old enough that DEC
made devices for both of them using only discrete logic, no ASICs? If they did
make UNIBUS and Q-bus devices w/o ASICs using only standard discrete logic, as
I'm sure they did, what did they use for drivers and receivers?
