Message #1 Posted by Luis on 18 Mar 2002, 8:54 a.m.

Somebody having or knowing where to find the schematics/circuit information for the HP-34C. I'm trouble with mine, which after the self test have an error#9 and 3 on display after pressing CLx.Don't seems to be some bad contact as usual (early model/non-PCB).
