Re: tape-O-matic

That rotogenerator is called a Georator, It is wonderful, isolating surges
on a typical machine shop line, having enough inertia to get by a couple of
dropped cycles. Yes, they used it to drive the logic, plus and minus 12
volts if I remember correctly. However it is really Obsolescent. That's
why I suggested when you brought the subject up, to get rid of the control
cabinet full of elco connectors, each planning on becoming intermittant
just when you can't afford it.

Yes, you can use the circuits. The first thing you do is regap the forks
on every elco connector and never swap boards without troubleshooting to
the board you are going to swap. You don't just swap rows of boards unless
you check the gaps on the elco connectors every time you insert a card. If
you get rough with the pins you will break them or push the mother board
pins out of the motherboard.

Do you really want to go up a learning curve that holds only obsolete
information? Or would you really be better off going up a current
leaaarning curve.

Jon is right asgain. The control was developed (Not using the more modern
spindle drive) in about 1962. Those discrete boards suck up all the
current the georator puts out. Gas heating for your shop is much more
practical thean electrric heating with that control. In thae summer, when
the ambient temp reaches into the mid eighties, the silicon reaches thremal
runaway. The normal procedure is turn it off or air condition it.
