[Coco] rom swap with eprom?

[Steve C.]

Thanks for that, it will be helpful. My main source of confusion at this
point is the coco service manual, which has a layout of 40 cartridge
signals, with a schematic on the next page showing 36 pins on the cartridge
port. The cart itself has only 28 pins! I think I will concentrate on the
chip end of the thing as per your reference link and ignore the edge
connector confusion if at all possible.
