I have a QBus
board that I would like to identify. Its made
by Digital Pathways and the model number is TCU-50 Rev A. It
is a quad size board and there are three small batteries in
the top right corner of the board. There are no peripheral
connectors on the card, so I figure its some type of clock
or possibly a small amount of battery backed up storage (the
machine it was take from was used for collecting process
data). Any ideas of what it might be?
It's not a Q-bus board - what you have there is a Unibus clock board.
(There is a Q-bus version, not surprisingly called the TCQ-150.)
I assume that the board is mis-labelled or some mistake has
been made, since I removed it from a working qbus system (an 11/73).
Is it possible to put a Unibus board in a qbus system, I know it
won't work, but will it physically fit into the backplane?
I had trouble setting the clock on this system, maybe this is
the reason.
