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, it even requires that a grant card be installed if that RH70 board set isn't installed. I can dig through the print sets for hours to find this out, but if someone knows offhand I'd appreciate an express clue delivery. Thanks, -Dave -- Dave McGuire, AK4HZ New Kensington, PA
