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.
