"Boy, you'll really go far out of the way just to avoid using a programming adapter... ;-)" Yes. Or a test clip. Because I'm working on a recipe not just on my own 2 or 3 machines. I could just buy a socket and 3 inches of ribbon cable and one inch of velcro and no adapter board at all if I only cared about one machine one time. --- That's what I keep missing: unsoldering the original socket on one machine doesn't sound too bad, but having to do it on every one??? --- There is plenty of room to stick a chip upside down on the motherboard next to the original socket and just run a couple inches of ribbon over. --- As a matter of fact one of my early prototypes sort of did something like that: a small board that had sockets for both a 32KB RAM and ROM chip upside down and beside the original system ROM chip. Unfortunately a couple of small caps got in the way and had to be relocated, so it wasn't entirely plug and play. m
