Now he needs to go dig up some old computer magazines with program code listings.
My affection toward the TRS80 actually lies in the fact that I never had one. I had an Apple.

It was a great experience except for that pesky little aspect that kids in the early eighties who were into computers tended to get the ever living hell bullied out of them.
