HP31E Missing Pin
Hi all,

I was asled to try and fix a HP-31E. I haven't been inside one before but I assume a pin missing from an IC is not normal.

Hard to image how it went missing except by faulty handling at some stage of its shortened life. It will be somewhat tricky to try and repair it, but perhaps the missing pin caused electrical damage.

The battery ribbon is quite corroded as well near the battery connector which I guess is common.

cheers

Tony
