I've had a Zetron 45B kickin' around for a few years, and now I'd like to use it ...
Problem is, like many others who live too far away from parts sources, I have a tendancy to borrow parts from one gadget to build another. At one time or another, I borrowed U2 and U30 for a controller project. I believe U2 was a 6840, and U30 was either a 567 or 555. And of course I don't have the original schematics, so I can't be sure what I need to get the unit up and running again. If you have a 45B manual, could you kindly look up U2 and U30, and let me know what part numbers I need. Thanks.
