The Model 1 TRS-80 was a small piece of TRASH that offered a Z-80 computer with limited I/O - tape drive was most common, no inherent sound capabilities, limited graphics 128x64 dots (or rather, blocks) per screen, 64 characters across by 24? (25?) in normal text mode.[D I believe it came with 32K RAM, and automatic BASIC interpretation. i.e. The Model I was a terrible attempt at a computer, but was appreciated by schools because it was from Radio Shack, and could be used to teach something about computers to students without choking on the bill of buying a mainframe (NEANDERTHAL computer) There was a Model II computer that didn't last long, but I can't quite recall what it was, or the changes that made it Model II. Model III was the HULKING giant that introduced disk drive options IN unit, and a nice expensive upgrade available for HIRES graphics, although by todays standards, these should be called LORES. I believe the Model IV was their only REAL contribution to the computer world, and {we are still dealing with a HEFTY price tag, and a small lack of consideration for miniaturization. Basically, I wouldn't repair it..I would try to offload it on a electronic hobbyist hard up for parts., [D Rich I learned BASIC on the TRS-80.
