I have successfully used an 8088 with 640k to set up a network file server using the dos networking software. The only problem is with all the TSR programs in memory there isn’t enough memory left to run other programs while using it as a server.

Hmmm. I seem to recall something... an EMM386 Memory Expansion Board (actual name could be off a bit) for the ISA bus that was quite popular back then. Dunno if it would work on an 8088 machine, though. Perhaps on a custom dual-cpu 8088 or 8086 board, but you would probably have to customize the instruction set if you went that route.

“Dunno if it would work on an 8088 machine, though”

8088/8086 only supports 1MB memory addressable. 640k usable. The only memory expansion boards available are paged memory. You can’t use paged memory for active or TSR programs.

an EMM386 Memory Expansion Board...

Wait: Extended Memory Module or Expanded Memory Module -that was it!
