The seller thinks this may be a drum memory, but it is clearly not. My
guess is that it is some kind of clock generator. Anyone recognize
this?

Sounds like a dedicated pulse-height analyzer. DEC sold a lot of machines used
for this purpose, but there were dedicated units that had no CPU, but had
memory, often core.

This looks like a GP-4, though I am suspicious that parts of it have been
modernized. The GP-4 had a drum memory.

On the 1630 series, the active logic is all in the pods. The connectors on the

Here is an idea I haven't tried, but might work: Take some unoiled paper or
