Thanks to Johnny Billquist our intrepid Swedish pdp-11 collector we now have an answer to the 11/94 problem. The answer is any M8190 CPU and any M8637 memory. CPU in Slot 1 Memory in Slot 2 and 3. So CPU's M8190 KDJ11-B M8190-AD KDJ11-BA M8190-AB KDJ11-BB M8190-AC KDJ11-BD M8190-AZ KDJ11 Memory MSV11-JD M8637-D 1 MB ECC PDP-11/84 or PDP-11/83 MSV11-JE M8637-E 2 MB ECC PDP-11/84 or PDP-11/83 Before I go to the dealers does anybody have any of these?
