If you were wirewrapping or point to point soldering, you
might consider 2114 static rams. Might be easier to get
hold of thah 2101/2102s or 1101, but they won't fit into
the original or copied Mark-8 boards.

The pain and weakness of the Mark 8 design is the bus
connection scheme- soldered wires and molex across the top.
It would be better if you can use RA SIP connectors..
