PDP-11/84, PMI and Q-bus

Hi Jerome, Sorry I did not pose the question very well. I am trying to get back to the original issue. Which is: 1. I have an 11/94 with a missing cpu board. 2. The correct CPU board as you know is too expensive. 3. Please will somebody give me a low cost alterative in a form I can understad. 4. So all I want is for somebody to say is something like: " Put CPU board type KDJ11-xx (M????-??) in slot 1." " Put a memory card type MSV11-xx (M????-??) in slot2." " Put another (optional) memory card type MSV11-xx (M????-??) in slot3." or what ever order is correct and will run in a PDP-11/94. (xx = please supply correct suffix) (M????-??) please supply correct module number) 5. So far I know a lot about what won't work but not a lot about what will!!

So the answer will be found in the early replies: MONEY!! If I remember correctly, the PDP-11/93 CPU is still much more expensive than the PDP-11/83 CPU when combined with PMI memory. Now if you have an RT-11 question, that I can probably answer.
