Hi Philip, I have found your inquiry on https://www.classiccmp.org/pipermail/cctalk/2015-March/005247.html.
I have a Problem Solver Systems (PSS) RAM65 card that I would like to get working in my IMSAI 8080, but I can not find any manuals for it online. Does anyone on the list have a manual they could possibly scan for me. Much thanks in advance. Philip I have the same board but now information. In meantime did you get a manual or information about the RAM65? It would be glad if you can chair the information to me. Best regards Martin (Germany)
