Thanks for the reply.
I have 1, 27,28 to 5volts.
26 NC
And 20 to GND 14.
I bent the address pins out that need changing and am using an edge connector to temporally rewire the ROM chip rather then modifying the board. I am still waiting for the 2363/2764 adaptor board.
I am then checking my work by ohming between the rom chip and the CPU lines.
Mark,
I am importing the rom file with these default settings. The software has a verify option that reads it back and it passes. This software is what I am unsure of. I may trying making a rom for a different machine just to see if what I am doing is working. My tandy color computer has socketed roms iirc.
