Outstanding. Thanks, Tom. You know... I'm still going to try to get my current loops setup working. Now that we know the problem may have been the diodes, I can fix that and try again.
Tom, how far did you get? I suppose you set the 2SIO board to address 20. You mentioned that you put the teletype on port 1. So that means the PC was on port 0? Which order did you have these two?
Then, did you (would you) have to do anything for basic to recognize the teletype on port 1 and use it as the console? How does basic know that the "console" is now at address 22?
