How are you interfacing to the bus and is it
Q-bus or UNIBUS?
unibus. the chips are not that hard to find.
A couple of us were talking off-list about ways to interface to Q-bus
and transceiver chips for that bus are certainly hard to find (at
least we don't know of any sources for the actual DEC transceiver
chips or clones).
Is the situation different for UNIBUS?
No, not really. UNIBUS and QBUS essentially used the same technology.
There was a big long thread on this issue earlier this year on cctech.
Search the classiccmp archives for 'unibus transceiver' to get to it.
