Re: [opensuse] Ancient History
While we are going down this rabbit hole, I have a complete TI 99/4a system with tape reader, 5" floppies and expansion cabinets (2) and some of the rom software: DOD, Calc, etc plus manuals. Been trying to find it a new home. Need to find a history buff or museum or something. Ancient History is the thread, hope I'm not hijacking.

We're going well off-topic, but this contrasts starkly with what I was taught and what my son is taught now - as long as the method you've applied and documented is correct, the end result is less important, a minor typo on the calculator does not detract.

So, a Mars Lander also suffered from this metric/British/American measurement unit fiasco? I didn't know about the Lander. The one I do remember was where the mirror for the (?)Hubble telescope was incorrectly ground/polished because the measurements were misunderstood.

Me too, but it still failed. The other problem was the battery. It had two or three 1.2V NiCd batteries, with a converter to get 9 volts (instead of using a 9V battery directly). The charge lasted for too short a period, and of course, there were memory effects. - -- Cheers, Carlos E. R.

In our front office we have a SEL 8000 complete with paper tape reader, teletype, and switch panel, made in the early 70's. I still work on their products from the mid/late 70s. First true 32 bit super-mini. Mind you, I never had one in my home, but these things are actually still out there in use. We had a 32/55 (3 board wire wrap CPU set) in the depot for repair late last year. https://en.wikipedia.org/wiki/Systems_Engineering_Laboratories Talk about ancient history, I still work on this old stuff.

My first computer I programmed - in FORTRAN - was a Pr1me 25/30. So-called because it was a 300 chassis (I think the 100-series was pretty much a rebadged MULTICS Honeywell), with a Pr1me 250 cpu board in it. It ran Pr1mos v18.3, a very nice little OS for its time. I still miss it (and its successor, v19.4). The v18/v19 transition was a major step-change - it died about v23 which superficially wasn't much different from v19.
