HP8161A repair part 2
« on: December 18, 2022, 10:48:07 pm »
Hi.
I had bought a 8161A in bad shape as a fun project to learn more about old HP hardware.
After some work I did manage to repair it and then it found his place in the collection of test equipment that get used quite rarely.

Recently I tested it again and found out that the keyboard was completely stuck. No response.
After a bit of digging into the SW I am now suspecting that the EPROM has begun degrading and the code inside is not anymore valid.

Anybody with one such equipment willing to dump the EPROM code ?
Maybe a 8160A would somewhat compatible.
The EPROM is on a socket, so it is quite easy to pull it and dump the code.

Cheers
Filippo
