I actually have a good regulated 5V power supply I found on the junk
pile at the Habitat Restore shop, I guess they didn't know what it was
and threw it there. I have some old PSs from printers too, and the big
one I use to drive my CNC machine, has a coupla different voltages on it
(it came out of an old film developer). And some computer power
supplies. What I need is time for my toys!
How's that car coming along? Had any time to work on it? Warming up a
bit, be nicer in the garage.

Seriously, I'm quite jealous. Now all you need is a voltage supply or
two, a resistor box, a bunch of patch cables, a nice wooden work bench
with stool and good lighting, and something interesting to diagnose or
build.

It's the thing that you use to measure something -- a little metal probe
you stick on a circuit or component, the other end plugs into the scope.
They have to be made properly with impedance and capacitance and such to
allow for frequency measurement and not to alter the circuit much while
you are doing the measurement. I found a writeup on how to bodge one
up, but they are cheap enough to buy so I will get a couple.
I am excited, I have wanted a scope for a long time, this one is nice!

What is the purpose of the probe? Does it protect the scope in the
event that you put the probe in somewhere hotter than you expected?

So I bought the Tek 2445 for $100, it turned on, showed some stuff on
the screen so I guess it is working. The kid said his brother used it,
left it at his house in the closet some time ago, so he was unloading
it. Seems like a good price, ebay has them for $400 give or take so I
guess it was a decent deal. I'll order some probes

and see if I can get dangerous.
I found a great lab handout from MIT 6.002 - Circuits and Electronics
lab, tells how to use the thing to do all kinds of stuff. I guess I am
almost in bidness with a new toy!

This series is the last of the (and best of the) analog scopes from
the top maker of such. Except for its Achilles heel IC. There are
some benefits to the later digital scopes, but I prefer the analogs,
at least where they will do the job. For GP work, they certainly
will.
If you don't want it, I do! (OK, shipping is an issue.)
