There is a 4-channel plug-in (presumably a 3A74) in one of the 500
series Tek scopes at the radio museum here. Not sure which 5xx base
it is in. I'd love to be working on it.
I have this nagging fear one day I will go in to the museum and
somebody will have thrown out the tek scopes.
Have you ever heard the phrase "justifiable homicide"? OK, kidding -
mostly. - Ian
I know the feeling, but [throwing them out] wouldn't be
unprecedented. We (the museum - including me) throw out a lot of
stuff and there are widely-varying opinions about what to toss and
what to keep. We have very limited space (we just got rid of a couple
of dozen low-end tube scopes), the teks do take up a lot of space,
and I'm one of the few/only there who appreciates them.
There have been a few occasions where things have been dumpstered
before I had an opportunity to divert them away from the dumpster,
e.g. some nixie-tube calcs, a SAGE 68000 system, etc.
This site is interesting, it attempts to track some prices:

Everything is dirt cheap, EXCEPT the 570. There is one on ebay right
now for over 5000$. Coincidentally, the unit came from UBC and is
being sold from a location within the region here.
