HP-34C Power Circuit
Message #1 Posted by Julio Moreira on 24 Aug 2005, 12:09 p.m.

Hi to all.

Does anyone have a schematic of the flex circuit (ribbon) of the inside power supply of HP-34C ?

I have one HP-34C where the flex circuit is dead and I whish to make another one.

Thanks,

Julio César

Yes, it should be on the HPCC schematics CD-ROM. That disk contains 'representative' Spice schematics, I think it's the 32E and 33C. But all -E models are much the same as the first, all -C models much the same as the second -- in fact the main difference between -E and -C models _is_ the power converter circuit.
