So what would y'all recommend for logic analyzer/oscilloscope type
tools that are useful for vintage computing (i.e. their max
bandwidth/speed can be slower than needed for current tech) that are
also affordable?

I know Tektronix and HP are major manufacturers in this area, but I
would know what to get.  *Lots* of these items go up for auction via
government liquidation at the local Hill AFB, so if I know what I'm
looking for I should be able to eventually get something by low-bidding.

Suggestions?
