Paul Holmgren documents his experience getting a 64K Non-Volatile RAM board — sold by Tom Bent and Tom Woods — working in the TS2068’s DOCK port. After initially struggling to make machine code run from the board, he eventually cracked the required POKE sequence and system variable adjustments detailed in the NVM owner’s manual.

The article walks through the full setup: relocating the PROG system variable, the seven POKEs to 32768–32775 that configure BASIC and machine code placement, using address 26688 for machine code storage, and toggling between DOCK and HOME memory with POKEs to 23750.

The practical payoff for Holmgren was running his BBS program out of the DOCK port while keeping the full 38K HOME bank free for variables and message storage. He closes with a note on the NVM board’s usefulness as a testbed before burning programs to EPROM.
