I am posting this for a friend:
I would be interested in hearing from anyone who has used an IBM PC/AT to
DEC Q-22 bus adapter from BIT 3 Corporation. We have been trying to con-
nect an IBM PC/AT to a DEC PDP-11/23 or /73. In particular, we have chosen
to use the 128k bytes of dual-port RAM, which comes as an option on the
adapter, as the only memory on the QBus. The problem comes when we try to
run DEC's RT-11 operating system. The system gives the appearance of
booting normally, however KMON does not recognize any commands that are
entered. BIT 3 Corporation says that they test the hardware in both the
PDP-11 and the VAX machines, but they do not use the RT-11 operating system.
On the surface, they do not see any problem with useing the dual-port RAM
as the only memory on the QBus, but they can offer nothing beyond that.
Any suggestions will be greatly appreciated.
