compatible applications, languages and programming utilities, in addition to standard
Apple Software."

I've seen them advertised for $20. I'm sorta interested if the price is
reasonable.

Having always wanted an oscilloscope (but being very cheap), today I picked up a Tektronix
422 portable
oscilloscope with ac/dc internal/external power supply at a thrift store for $12. Just
the instrument itself.
So, first I want to see if it functions at all. I don't have the power cord, and it
takes an odd six-pin cord. The
internal batteries are, of course, discharged. Anyone have a power cord, or source for
one, or at least the
plug?
If it powers up, I would like to get it apart. I got the power supply off with no
problem. Anyone have a basic
assembly diagram?
If it then seems worth while, I would like the manuals and probes. Suggestions?
I know it is only 15 MHz, but that should be plenty for computers running no faster that 4
MHz, correct?
All help appreciated.

Try this link:

tart=20&sa=N There are several hits to manuals listed. As to wether the
stock on the manuals is current, I don't know.

New subject: "Big Iron" bracket, Dec? P/N 7114031701E
I got four of these in a box of DEC stuff this weekend.
About 12", 4lbs ea. and very strong, qty 4.
1.75" U shaped, large grain steel, probably can
support tons. Not for MicroVaxes I imagine.
Will give them to a scrapper if no-one here wants them.

Wonder what these are for? Possibly for mounting something to a rack?

Take a peek at the Tektronix web site and then see whether you can find the
backward reference to the Sony 'scope, which is what this model really is.
Sony has a good likelihood of having the doc somewhere, though it may not be
accessible. Try a Google search as well. Last but not least, try the
newsgroup sci.electronics.equipment. Somebody there probably has the stuff
you need, though you may have to get out your wallet to get it.
The bandwidth is adequate for the most rudimentary of applications, but, for
example, if you need to examine DRAM timing, you may be at a disadvantage.

If it is Sony then parts should be available through Sony Parts
warehouse in KC. You might need a sony Xref number. Just hold on to
your wallet when you see the bill. Ain't cheap but they usually have
stuff like that.
Tek is pretty good on getting stuff for their scopes; I'd try there
first. And there are several dealers on the net that deal in used Tek
gear as well.

Tektronix hasn't been very good about keeping parts and manuals in the
last 3-5 years. They no longer have manuals and parts for most of their
older scopes. I made the mistake of not ordering all the manuals for my
tube based scopes before they got rid of all their microfiche. They even
sold off all the parts and manuals for a particular scope I have to GTE.
GTE would not sell me the parts I need, and had the nerve to suggest I
scrap the scope. I'd have to look at the unit to remember the model
number, but it's a 60MHz scope Tektronix made in the mid to late 80s. Even
though I really like older Tektronix scopes, I'd have to really think hard
about buying any new gear from them because of their recent change to not
support *any* older gear.

They're not so bad, methinks. Those tube-type 'scopes were discontinued over
25 years ago. I often find I can't get parts for stuff I bought new less than
5 years ago. I know for sure that the tube-scopes were no longer supported in
'79 because that was the basis for my decision to buy a nea-new TEK 465 for
considerably more than I originally wanted to spend.
The example regarding replacement parts that I have to remember is the car I
bought new in '77, for which the US mfg couldn't find a replacement engine
when , 6 months or so after I bought it, brand new and built to order, the
engine blew.
I haven't bought a U.S. made car since, nor has anyone else in my family.
