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.

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?
Some first pictures can be found here:

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?

I found several spare switches and handles for what I believe would be a
PDP-11/10 or similar. The handles are white and are marked 1210785.
The switches are C&K 7121 (on-on) and 7128(on-momentary on).
Can anyone confirm?
Thanks,
Kyle
They came standard on the industrial series of monitors from IBM.

Apparently, the stuff is still made:

Perhaps you could swap in a Toshiba 9-inch green monitor from a Kaypro 2 or 4. Seems to have
the same 4-pin connector, and used Kaypros are cheap. There's a standalone CRT on Ebay right
now, including yoke, for $19.99 + exorbitant shipping:

Seeing the discussions about the HP150 and the HP-IL stuff reminded me that I have an HP 150 with the 3COM Ethernet card, but I've never found any software for it. I checked hpmuseum.net and they don't have software, and didn't even have a picture of the card until I provided them some pictures of mine. Does anyone happen to have the software?
Not my auction -- just noticed this:

Apparently includes software and documentation as well, who knows how much
or what it is.
Local pick-up only (in MA), but a nice haul for someone, for a decent
price. I think this was listed last week and didn't sell...

I am not sure about finding a CRT that will find that housing. It is VERY
tight in there and the cables are routed every which way. However, you could
always use the component out with another monitor if you wish. The 5155 uses
a std. CGA video card. I've hooked up a IBM 5144 to it in the past and it
does make for a sharper image.
