Lars Brinkhoff @larsbrinkhoff.bsky.social · 27/06/2025The Freeway Crossing game was written by Michael Irrgang in 1971, for the IMLAC PDS-1 computer. He made it for Earl Hunt, who was going to use it to measure reaction times in a psychology study. The game play is similar to the arcade game "Frogger" from 1981. 2225

Reposted by Lars BrinkhoffCrazy Eddie's Used Computers @dectape.bsky.social · 22/03/2025March 22 marks the 60th anniversary of the introduction(*) of the Digital Equipment Corporation PDP-8, which more or less introduced the "minicomputer" as a new category of computer. It cost a mere $18,000 and fit on a desk, and while it was a small, simple computer, it became extremely popular. 2137
