Christian,
I absolutly agree with David s post.
Back in the ' '70 when I was maintaining 3 x HP 2116 B running 24/24 7/7
FOR around 10 YEARS, the ONLY memory related problem that I got was
traced to a faulty transistor !!
Then I have a new fault ;-)

I have other 2116 cpu manuals, getting time to do anything to find them or look
for differences is a problem.

Christian, I tried to track down details of the 1820-0183 and the manuals
appear to say it's an RCA item, part number 80170 but I cant find anything
with that number anywhere - you are probably on the right track with a
CA3082A or similar.
My experience in fixing similar faults on the memory boa
