Tek 2230 'scope

It's not a bad buy if the thing works, and it probably does.

For most troubleshooting of classic computers, it should be WAY beyond
adequate.

One nice thing (feature) that digital storage scopes support is capturing a
set of samples and forwarding it to your PC, where you can massage it
against the output from a simulator, given that you have a schematic of the
circuit under study.

The really SUPER thing these guys have is the ability to trigger on a very
infrequent event, yet produce a very readable display. I spent a fortune on
a TEK 2467 with microchannel plate-enhanced display, just so I could see
oddly occurring events resulting from metastability. The digital 'scope
should do that very nicely.
