First you ping it to see if it's really there:

A properly functioning TK50 should be able to load and eject tapes
even if not plugged into a controller.
Can you rapidly switch in/out the red light/button for three or so cycles,
with the final position being "out" (unload)? What happens when you
try this? If *nothing* happens, then there's something seriously
wrong (electrically) with this TK50. If it attempts to unload but
doesn't quite do it, and ends up with the red button blinking rapidly,
then there's probably a mechanical problem, most likely with one of the
capstans or the corresponding optical interrupter.

Doing a reverse nslookup may work, *if* they've got a PTR record and
they haven't chosen to purposefully put wrong information in the PTR record.
A traceroute may sometimes give useful results if the IP address
is actually in the routing tables. If it's not in the routing tables, you
may as well pop Elvis into the 8-track and listen to "Return to Sender."

In my experience this particular problem is often due to the capstan
near the take-up reel side. If the tape gets pulled over the capstan
without the capstan actually turning, the TK50 gets confused and thinks
that no tape motion is taking place, so it gives up. Check that all
the capstans turn nice and freely before assuming the problem is in the
electronics.

Absolutely - in fact, before loading a TK50 in unknown condition it's
always a good idea to make sure the take-up doo-dad is in the correct
position and in good shape.

Several times in the past I've ranted to this list about my hope
for a more ancient version of DejaNews, a web archive of old
Usenet posts. Below is an e-mail I received from someone who
has the start of an archive. He's searching for more volunteers
for the project. I think this would be a tremendous resource
for classic computer collectors and historians.

Been thinking about a potential Usenet archive restoration project
lately, how such a project might work.
I don't think it's a one-man job -- too many people are probably going
to have different ideas on how to store it, availability, interface,
etc.
This is what I think needs to happen:
- there needs to be some kind of public discussion area for the
project (like a newsgroup or mailing list)
- a repository needs to be put in place, where people can send their
archives. any size would probably be good enough to begin with, even a
few gigs. hard drives are cheap now and it shouldn't be too difficult
for someone to be able to get at least 10gb, which i think should be
enough to at least begin assembling some of the old years, and
whatever misc. stuff from pre-95 that people have?
While I'm very interested in this, I don't have time to oversee or
coordinate it. (I assume that you don't, either?)
However, I've been assembling what notes I can -- URLs of known
archives, addresses of interested people, related threads. I've begun
putting all this together in html and plan on putting it on the web,
just to make a convergence point for likeminded individuals -- maybe
it might provide the impetus for someone else to begin such a project?
Or at least get the attention of someone who has a 20gb hard drive on
some ftp box at some university or organization somewhere, where some
of the old archives could begin to be reassembled? (I'd think such a
restoration project would make a great research project for someone,
maybe?)
As I think I mentioned before, I've got some archives from specific
groups, and a lot of old threads and even single articles saved. If there
was a coordinator and a system in place (even 1gb to start? or a box
with access to a cd-burner or some other removeable media?), I bet a
post to slashdot would draw in hundreds of people like me, or more,
with their old archives.

P.S. On a related note, I'd like to see an open-source replacement for
imdb.com happen, but again it's not a project I can take on right now.
Found this in another newsgroup:
--------------------------------------------------------------------
We have a Prime 9650 computer available to a good home.
This system was under ComputerVision maintenance until they dropped support
for the 9650 last July. There are two system cabinets and a half-height
tape drive cabinet.
Our company was at one time a Prime business partner. This machine was
purchased under an agreement that allows us to resell the machine WITH the
operating system after a usage period (long past).
Stuff that is working 100%:
9650 CPU, 6 mb memory
PRIMOS Operating System (32 user?)
ICS-II 32 ports
Y2K Primos tape set (not installed)
(2) 315 MB Disk drives (one nearly "new")
8mm Prime tape drive
COBOL Compiler
FORMS, MIDASPLUS
PRIMELINK, 10 user.
Lost of Manuals
Additional stuff that doesn't necessarily work:
1/2" reel tape drive 3200 bpi (needs minor work)
CDC 496 MB Disk drive and cabinet (crashed probably)
1/4" cartridge tape drive (worked when we unplugged it 5 years ago)

Sounds like a really cool system.
The system is located in Greenville SC and consists of two LARGE cabinets
and one smaller one. The whole lot probably weighs 1000+ lbs.
As always, reply to the original poster, not me!

I have a problem with one TK50 that the connector between the motors
and one of the PCBs is flaky. It will load tapes sometimes, but
eventually, the tape goes slack in the drive and won't rewind. I've
fiddled with it enough that the next time I need to use this particular
unit, I'm going to take Allison's advice and solder the motors to the
board.
I would remove the covers and see what state the tape is in. It might be
half-in, half-out, it might be stuck on the leader, indicating a problem
with the optical interrupters as mentioned before. Also, when you get the
tape out, finally, inspect the barb at the end of the takeup leader in the
drive (not the cassette). If it is crimped, you'll get unreliable loading.
If it's missing, you won't get *any* loading.

I dunno; it seems to me as though natural selection would take care of the
problem better. Any kids dumb enough to get trapped inside a refrigerator
don't reproduce, and therefore the defective self-preservation gene doesn't
get passed on. Darwin would be proud! Beats the hell out of wrapping the
whole world in padding and taking away everything that might possibly kill
some moron. Historically, it's been things like rockets, guns, swingsets,
mercury switches, fireplaces, and all the really good fireworks that The
Establishment has deemed too dangerous for us unwashed masses to play with.
Wonder how long until some loser chokes on a mouse ball or strangles himself
with the cord while trying to plug in his new business card scanner and mice
are required to come with warning labels?
