-embarrassed look-
I was a bit of a computer geek before Pong came out.
Had to be.. it was my job.
Electronics Countermeasures .. hydraulic tuned maggies ..discreet transistors on circuit boards ..
..you could see the AND gates by following the printed circuits no less.
Look at a circuit board and see it was a bistable oscillator.
Punch cards then mylar tape .. assembly language then hexadecimal
.. finally loading a computer into a plane instead of a 200 lb hydraulically tuned transmitter
VAX ..with the huge magnetic drum in a semi-trailer ..hey man, it was portable at least!
All many years before I found Air Warrior on GEnie with G-Man's help
