There have been some models that show up pretty rarely here, notably
the 5030 & 5031 that were few and far between even during their
lifetimes. I wonder, though, about a few others that were not
that rare 35 years ago but seem to have nearly vanished.
Comes to mind:
434 -- 25 MHz bistable storage with a switching supply that predates
the 155-0067 control ic. GE Medical had a bunch of these.
432 -- The 434's non-storage brother
442 -- Much like a T900 series in a metal cabinet
Has anyone collected these portables?
