Anyone have copies of the service manuals for Tandberg, Archive, or Wangtek SCSI QIC tape drives
TDC 3600/3800, Archive 2160S/2150S, etc?
I picked up a copy of the product manual for the TDC3600 series, and I realized that I don't have
any maintenance manuals for the SCSI QIC products.
On a 4116, pin 1 is -5V, while the 4164 is N/C. Every guide online says
to snip off pin 1 if migrating to 4164s in a 4116 footprint, but I don't
understand why. If pin 1 on a 4164 is truly N/C, then why does it
matter if the pin is inserted?

Hello all,
I got a batch of orginal Convex tapes with ConvexOS for C1xx, C2xx, C34xx an C38xx.
This tape seems to be stored in a quite moisty environemnt and are partial molded.
Since these tapes, their content is of high value for me, beside of this I don't know if ConvvexOS is somewhere archived, how to process these tapes to be readed successfully.
@Al: shall I send this tape to you before starting my own experiments?
Andreas

My MM5314Ns are digital clock chips, not display drivers, and they have 7
segment outputs not really suited for Nixie tubes at all...

Coming across some old PDP-8 files from him today reminded me, has ANYONE
heard anything from Jeff Russ? He may have retired by now. I think the last
time I saw him was when I went out there to visit in the early 2000's.
Well, we finally managed to pick up the huge collection of computers
>from a basement in enschede, The Netherlands.
Is was quite a project.
after visiting the place to get an idea about what there was and how to
get it out of there, we made a plan. the key problem was that almost 90
percent had to come through a small hatch 80x80cm. :-)
and the collection included pdp11's, Control Data diskpack drives,
microvaxes, SGI's, IBM RT machines, an IBM system/36 and a lot more
heavy stuff.
We rounded up around 15 people and a lot of transporting hardware an we
managed to get everything out in one day. :-)
To have a souvenir of the occasion we set up some camera's taking a
picture every 5 seconds and made a nice film:

We are still repackaging things and havent even started to look in
boxed. :-(

Since I've never seen this described anywhere
Older carts are easy, the reels and roller are held in place, the later ones
are not since the cover holds them down.
Assuming you're right-handed:
Put the cart on a table so the capstan roller is to your left
Take the band and place it on the capstan roller, pull it taught with your right
index finger and snake it between the two reels.
Put your thumb on the bottom reel (the one that normally has little tape on it)
your pinky or next-over finger on the capstan roller and index finder on the other
reel. Rotate one of the reels so the tape is tight, and apply pressure with all
three fingers to keep the tape tight.
Place the band across the bottom of the reel which has the most tape on it (depending
on if the tape was at the load point), by moving your index finger towards the appropriate
bottom white band roller. Make sure the band across the bottom of the tape is near the
center of the tape roll (you don't want it popping over or under the reel in the next step).
Now, you tighten the belt. This is the tricky part. The band really wants to go under one of
the reels as you do this. Place the band around the white roller closest to the supply reel,
making sure that the roller doesn't move upwards on the pin. Bring it over to the other roller
apply tension and pop it on. Hopefully, the band hasn't popped under something as you do this.
The most often thing that happens is the band goes under the capstan roller or the supply reel.
Now, the belt is on, but there is some slack in the tape. Take the band across the reel having
the least amount of tape and move it away from the reel, releasing the tension on it. Spin the
reel to take up the tape slack, and release the band.
The things I had the hardest time with were the rollers moving up and down, and thinking of a
simple way to tension the tape; move the band away.. duh..
Hi
I quite a lot OpenVMS manuals that needs to go to make room for other
documentation.
It is paperback for version 6.0, 6.2, 7.0 and 7.2. Unfortunately no
complete set and some dupes. If there is any interest I'll make a
complete inventory.
There is also older gray and orange wall type manuals.
Price is free for the cost of shipping from Uppsala, Sweden.
Unless a bidding war ensues of course :D Beer money is always welcome.
Regards,
Pontus.
Hi,
we got a Zilog S8000 this weekend. The system is really nice and in good
shape. Thanks to Oliver Lehmann, there's a bit of documentation for this
system (seems to be very rare nowadays). Our system had several errors
during bring up diagnostics that were caused by bad contacts in several IC
sockets (could be cured by pulling out all socketed ICs and reinserting
them). But there's one error left, and alas, our system is a Model 32 that
is a bit newer than the Model 31/31plus, the CPU board is different and
the error number is not in the hardware reference manual. The system also
doesn't boot successfully from the SMD disk, it is able to load the
primary bootstrap, but trying to load the secondary bootstrap immediatly
returns an error.
Here's what comes out on the terminal:
System 8000 HPCPU Monitor 10.1 - Press START to Load System
MONITOR POWER UP DIAGNOS
*** ERROR #0402 <03> 3600 3600 5555
TICS
ACTIVE PERIPHERALS:
SMC
TCC
SSB0
COMPLETE
MAXSEG=<3F>
> stand/boot
*** SMC ERROR
[
Question: What is error 0402 ? Did in the meantime more documents or even
tapes (ZEUS, SADIE) show up?

Just ?. BRAVO!
Not a great idea to stand up and cheer at my desk, but I might watch this video many times this afternoon.
This makes my whole week!
*How* did all that get *in* there?
