And now for something really off topic...

Yep remember the old dialing and remember having a party line. But way off track for the thread. Not even sure what it has to do with a trailmanor????

Because the guy who designed our Trailmanor would have been doing all the groundwork in the 1970's, and whilst waiting for his neighbors to get off the party line so he could dial 1 to make a station - to-station call to a potential supplier because he couldn't afford the person -to person rate, he performed more calculations on his Pickett N- 803-ES slide rule.

Then he went out for a beer.

Love the response.

Lessee, in 1970 my PC was an IBM 370, 1973 was using infrared detection and fiber optics to automate very large aluminum die casting machines, by 1976 was designing digital engine controls for military afterburning engines and using programmable controllers (relay logic) to run different engines on test stands.

So there were computers in the '70s, heck we flew to the moon on plated wire memory. Never used Al-Jabr per se but did use Boolean Algebra, set theory, and statistics a lot. Still do but now more putting Linux on Chromebooks & reprogramming my cars.

There were computers in the 1950's, but I presume they were vacuum tube based.

However,

Most likely a system 370 model 195

Could be, was modelling Corvette suspensions and transmission gear ratios mostly.

Yes, took two miniature tubes to make a flip-flop. That said the only tubes in a Bombe were to record the solution (and were in a rack at the top) but a KW-26 was all tubes (and don't ask about the dents).

ps "Hidden Figures" is a great movie.
