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.

Subject: Tek 2230 'scope
I picked up a Tek 2230, a 100 MHz two-channel digital storage oscilloscope
for $150 today, on a rolling stand. It shows signs of life in the sense
that the display works and the buttons seem to have some effect, like
stepping through menus.
I've always wanted a nice 'scope, even though I have very little
experience
using one. Where do I begin? I have no manual, just
the little tech ref
booklet. A manual sold on eBay a few weeks ago for $25 or so. It has a
half-dozen probes.
Was this a good deal? I found a number of refurb places on the web
selling
them for $1400-$2500.

The 2230 Digital Storage Oscilloscope is a combination
non-storage and digital storage dual-channel 100 MHz
bandwidth instrument. It is a rugged, lightweight
oscilloscope featuring microprocessor operation and
alphanumeric CRT readout of many of the front panel
controls. In the digital storage mode, up to three
waveform sets (CH 1 and/or CH 2) may be stored in a
save ref. memory and recalled for display at a later
time. The digital storage sampling rate is 20
megasamples per second maximum, and the acquired
record length is 4 k samples (1 k may also be selected)
for a single channel or 2 k samples for dual-channel
(Chop or Alt) displays. Manufacturer's Standard
