After spending some time and rummaging three HP-37E's I finally got my HP-34C working (somewhat). The unit passes the self-test, RAM is functioning and program storage works fine, though I had to implement a make-shift battery clip since the best battery terminal I had still had a missing terminal due to corrosion.
What's happening now though is that every time I shut the unit off and wait more than a minute generally, the unit will power back on with the PR Error displayed. Is this a failed cap?
Thanks in advance.
