Well, after the recent discussion of scopes for vintage computers, I've put
together a web page with a couple of pictures of two of my scopes. One is a
Kenwood SM-220 station monitor that I use with the Ham Radio stuff. The
other is a Tektronix RM-503 dual channel scope that I use for
troubleshooting the PDP-8/E and perepherals. In the photo, it is sitting on
top of a currently non-operational Sykes 7200 Dual 8" Disk drive.

That 503 sure is a beauty. Many of the older scopes I've seen of that
vintage were very dirty, and quite often had lots of dings/dents.

There is a Yahoo group for the restoration of old Tek
scopes. I have found the people in it very helpful.
The hobbies are somewhat similar, given that the older
equipment was so much better built and maintainable.

Wow. That Tek is a beauty... Unlike my Tek 466 analog
storage scope. I still
need a probe, new storage pouch (the studs are missing from the one on the
scope now) and a front panel cover (big blue plastic thing used to protect
the panel while the scope is in storage). But other than that, it's in great
shape. I got it in a test equipment auction for about 10% normal retail
price (40 GBP). And it works flawlessly. Did I mention I've also got the
service manual? I found it in the storage pouch when I was checking it for
damage after I got it home. It's still in as-new condition.
Dud Tek use any oddball parts in the 466 (besides the CRT) that are now
difficult to get? I'd like to stock up on spares for this thing before it
fails.
I've also got a Gould OS1100A, good condition (it works and produces a nice
bright trace), 30MHz, dual trace, delay sweep scope that I'm selling for
GBP100 ONO. Buyer collects or pays shipping. Anyone (preferably in England)
want this thing? After "graduating" to a Tek, I see no reason to keep it.
Later.

New subject: Vintage Scopes, another RM503!
Ok Vintage hardware fans...
Yet another Tektronics RM503 scope? Yep, complete, functional, but it
could use some tweaking, no screen burns is available in centeral MA.
Due to the weight, I'd prefer not to ship this, so local pick-up is
strongly prefered.
(It has a good power switch)
Any reasonable trade or offer will be accepted.

Not
sure. I think my Tek 466 dates back to about 1980.

In 1972? I got a military surplus Tektronix scope. I
think that the model
number was 512.
The oldest Tek I ever owned was a real oddball called a 514AD. I sold it
to a Tek collector. It was clearly an mid or early 50s type.
Regarding military scopes - BE CAREFUL. First, a new hamfest find may
look like a Tektronix, but it actally may be a Lavoie. These scope SUCK
in a big way - unstable, unreliable copies. The best way to make
sure of the make is to see if it actually says "Tektronix" on it or if it
has Tek's manuafacturers code (a five digit number or four letter
contractor code I do not have handy). I think Hickock made some bad
copies as well.
Also, many scopes made for the military (most are AN/USM-somethings) look
like civilian models, but often have something deleted from the design.
Most of the time this is not a big deal, but if you have a choice of the
military or the civilian models, ditch the one in uniform.

About 5 years ago, I sold my 512 to a young man who was enthusiastically
trying to teach himself elctronics. $1
He's still using it, but now also has a slightly newer one (with plugins!)
