Jeff Tranter also ran the Enhanced BASIC on his TS2 build. It loads into ROM on his card from 0xC000-0xCFFF. This card is compatible with Jeff's design (it's based on Jeff's design which is a copy of the Teeside TS2 board so any software that Jeff got running should run on this card.
I added a 16KB internal SRAM to that range and uploaded Enhanced BASIC to the card and it worked.
A short program...
I could change the SRAM into ROM and have BASIC always ready to run.
