This "computer" had hard wired programming. If you want to make a change, you had to program it, using wire cutters and soldering iron!
ahhhhhh the good old days <G> at least it was harder for others to mess w/ your system, no? <G> My Ex used to work on a couple of that kind of box.. er room, er , building .... whatever <s> Mainly tho he worked for IBM's Fed Systems division... I got to play w/ some of the machines.. but not til the punch cards came in to "program" them.... Did your Vacuum tube system have a big RED button on the side of some of the stacks that said "Do not push" ???? There used to be literal "bread board circuits" in some of these units , similar to your wire cutters and sodering iron I suspect... Tho swapping out a board w/ all the tubes etc was probably easier than it sounds<VBG> How 'bout we take this to the OT list before we make the list Gods angry ?? -- j -- nemo me impune lacessit
