Imlac PDS-1 simulators?

Imlac PDS-1's used third-party memory modules. There are at least two
vendors.

The Imlac Sellam has uses what Imlac called MEM-1, and it has a large
cannon connector on the memory backplane.

My Imlac used MEM-2, where all the connections to the processors
are made with wire-wrap.

MEM-2 core modules don't have parity bits.
