Pro/File +5 is Tom Woods‘ database for the TS2068, with later modifications by Robert Fischer. The BASIC program carries the interface — menus, editing, print formatting — and hands the slow work to a 2,046-byte machine-code module loaded at 63488 ($F800).

If you’ve ever had a ZX81/TS1000, TS1500, or TS2068 question and thought “I’m sure somebody on the list solved this years ago…”, you were probably right. The trouble was finding it.

Timex was looking for the same thing from the other direction. Dan Ross, COO of Timex Computer Corporation, was vocal about the TS computers as educational tools. “Computers

There’s something quietly wonderful about discovering that other people have been building the same thing you’ve been building. Not exactly the same — differently the same. Same general idea, completely different priorities, completely different angles. Each one a window into the maker’s own preoccupations. I built Retro Pixel Converter over a few weeks, partly because

In June 1980, at the Consumer Electronics Show in Chicago, a few hundred people encountered something that would barely register on the radar of the American computer industry but would prove irresistible to a certain type of enthusiast. The Sinclair ZX80 wasn’t the show’s star attraction—that honor belonged to products from established companies with established
