I've been offered a Tektronix 422 oscilloscope (price is under
negotiation). Is this a decent scope or a piece of junk? I'm not very
experienced with oscilloscopes, but I want to get familiar with them
and this one was not disastrously large.

This is a dual trace 15MHz scope. It would be O.K. for low speed requirement
applications.
In measuring/observing signals, one has to take into consideration rise and
fall times, glitches, phase, etc. of the signal - so it's usually best to
have a scope that's about 10X the speed of the frequency you're interested in
observing.
For most vintage work you'd be better off with the readily available and
inexpensive TEK 4x5 (x=6,7,8) series. All are portable, dual-trace, have
delayed sweep, and reasonable differential capability (handy for core memory
scoping).
Cheers,
Lyle

I agree 100% here, these are the very finest of analog scopes.
I'd like to make one other recommendation, for the Tek 453. It's a
fantastic scope, and they're readily available at very reasonable
prices.
