PDP-11/84, PMI and Q-bus

Jerome Fine replies: EVERY time DEC answered that question, the answer was ALWAYS that the PDP-11/93 CPU is NOT allowed or able to use memory on the Qbus. I can attempt to find and old DEC catalogue, but I VERY clearly remember reading that Qbus memory of any kind was NOT allowed when a PDP-11/93 was used on the Qbus. Of course, considering that DEC sold the extra memory for about $ 3000 for the extra 2 MB (the PDP-11/93 board had 2 versions - 2 MB and 4 MB of memory), there might have been hidden reason for the information. Does anyone have a 2 MB PDP-11/93 board and have any extra memory active (NOT as fast probably but it still works) and running without any problems on the Qbus?
