I have a dual ported 32K memory card in this machine.   The memory performs exactly as the 'E expects, but in alternate clock cycles, the memory can be set and examined from a PC.

The PC software running under Linux, enables the PDP8E's memory map to be viewed and edited like any other disk file.

This does means the edit/assemble/test/crash cycle is much quicker.

I wrote my own PDP8 assembler in order to integrate with the dual ported RAM card.
