Has leader been pulled out of the cartridge at all? If not, then you can
just nudge the door-unlock solenoid (on the right side of the drive
near the front) and pull the cartridge out.
If the leader *has* been pulled out of the cartridge, trying to do this
will leave you with a big mess.

If it's not trying to move the tape at all, I don't think it's the capstan
roller.
One question that's vitally important right here: is this an important
tape stuck in the drive, or a scratch tape?

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

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

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

don't reproduce, and therefore the defective self-preservation gene doesn't

some moron. Historically, it's been things like rockets, guns, swingsets,
mercury switches, fireplaces, and all the really good fireworks that The

I thought I would put it on my workbench and power it up but that doesn't

With the help of many fellow archivists, I've pieced together the
first hundred or so DECUS RSTS-11 library entries to form a neat
web-accessible archive.
These RSTS-11 library entries date from the early to mid 1970's, and
were originally distributed by DECUS on punched tape and
DECTape. Perhaps the most recognizable of the entries are
RSTS-11-13 and RSTS-11-14, collections of Basic programs from
David Ahl that became the basis of the famous _101 Basic
Computer Games_. Here you get to see the source code in its
original RSTS-11 Basic form, from an era before Bill Gates and company
began writing their first Basic interpreter.
These RSTS-11 archives are available over the web at
http://pdp-11.trailing-edge.com/rsts11/
As I sort the thousands of megabytes of RT-11, RSX-11, RSTS/E, and
other PDP-11 related material I've got in the collection and index
it, I'll announce progress in these newsgroups. If you're interested in
joining in with the effort, hearing about works in progress, or
making your opinion about the web indices known, you're welcome

keyboard drawers, could you give me a model number? I've just realized
that that'd make the perfect kitchen terminal, and might keep an eye
out for them now, but it's awfully hard to search the 'net for
'nortel display phones' without getting bunches of current stuff.

I have had a similar idea, but for $200, I found a surplussed 486DX4 with
16Mb, a 540Mb disk, two PCMCIA, one ISA, all built into a wall-mountable
case with the LCD on the front. There is also an external floppy and
an IDE connector (once I've sussed out, the other I've passed on due to the
connector). It's ripe for Linux hacking, kinda like a laptop without the
battery or keyboard.

True. It's also possible to fit ancient Linux distributions onto 40Mb of
disk, but my record is 80Mb.

Ask me if I run RedHat. :-)

Unless you _like_ to swap like mad.
I've been playing with Floppy-based Linux boxes, primarily derived from the
Linux Router Project. My smallest achievement is a 486SLC board w/8Mb, a
multi-I/O card (for parallel), a NIC, no video and a Connectix QuickCam.
After the kernel loads, the one script snaps a picture, converts it to a
jpeg and ftps it to a spot on my web page. No hard disk. I even found a
case the size of an encyclopaedia, thus no room for the video card. Total
investment, $25 plus the cost of the camera.
I've been thinking of a similar thing for the wall-mount 486: boot from floppy
(or flash - I have an IDE adapter for an ATA card) and use networked storage.
I could use the internal hard disk, but I want an appliance that I can turn
on and off without worrying about filesystem corruption.
Anyway... massively off-topic, but fun.

Like trying to find a needle in a haystack.....
Would anyone know which handbook/manual the RX01 bootstrap loader is in?
I need to toggle in the RX01 bootstrap into a PDP-11/20 with 4K config.
If the bootstrap code is too long would anyone know if DEC distributed a
RX01 bootstrap paper tape version?

Chuck, there are a few things you may have forgotten. By the time one has
learned enough about parenting to be of use, it's too late for one's own
children. I've seen exceptions occur, in cases where when the first
"seating" has exited the scene, a second one is introduced. Those are the
exception rather than the rule, however.
Secondly, in an effort to make the nation's children safe from the few truly
abusive parents that we have in our communities, society has rendered
illegal the best and easiest-to-use tool, FEAR, sometimes best bundled with
GUILT, which is the other of these two tools for childrearing.
I had the harrowing experience of having a "counselor," and outsourced
individual provided by a district subcontractor, tell one of my sons that my
rather stern regimen of discipline was "too strict" and, thereby, validating
his desire to disregard my direction. Within weeks the boy was skipping
school, smoking, and not just tobacco, and who knows what else. His school
work was already poor, so that didn't fall off much. It was a long hard
couple of years getting him through high school and off to college.
Does this shed any light?

Hi! If it isn't spoken for and you don't mind shipping it (all charges

what the system might contain in terms of memory expansion and hard

Howdy folks...
I found these manuals on ebay - I already have a copy of all of these, but I
thought fellow HP 2100/2114/2115/2116 collectors might find them usefull. No
bidders yet, 2 days left in the auction, and the asking price appears to be
14 bucks and some change...
I only call it to everyones attention because they are not listed in a

I can't help when I drive down the street to stop and examine any computer
stuff I find on the curb. My kids get kind of irritated waiting in a running
car while I examine stuff..
Our lake community about every 3 years has a free drop-off for large trash.
I have picked up more "good stuff" than my wife will let me keep. I usually
volunteer so I can help unload and preselect any stuff before it goes in the
truck sized bins. Best find was a Toshiba 21" TV with a broken power cord.
Lots of old PS/2 and 286 machines and dot matrix printers.
The Kansas City surplus place fills bins with the following.
Bin #1 motherboards
Bin #2 fingerboards
Bin #3 power supplies
Bin #4 cables
I don't know where the documentation and media goes.
All of the cases go into the metal scrap bin. I have almost cried when I
find something really interesting as a case only in the metal scrap bin.

Our apartment complex's dumpster is a good source for home electronica (a
13" B&W TV, a cassette deck, a receiver reeking of cigarettes when warmed
up, 2 boom boxes, all in working order...), but I've come across only one PC
(clone 386). Who has good dumpsters for finding computers? Retailers?
Universities?
OT, sorta: Our local Goodwill stores here in Portland have the maddening
habit of putting all the monitors on these shelves, all the boxes on those
shelves, and all the keyboards in that big bin over there... Found the
keyboard for a Mac 512k or Plus but could never find the monitor&breadloaf.
Then, in the checkout line, I saw it in a cart! Didn't get the machine, but
the guy was happy I found the keyboard for him. Later, I thought Idiot! I
shoulda checked their dumpster for other odds'n'ends. I've volunteered
before to help assemble complete systems, but they don't have the shelf
space for it.
Good list, Jay.

Yes, and I got a spam from an easter-European company offering to make up to
16-layer boards (large, but I don't remember how large) for $26 each,
quantity 1. Silkscreen and Solder mask were extra. Now I 've got to see
where I stashed it.

It's also widely used in arcade game collector circles for restoring control

Thats a vaxstation or a VAXserver and definatly not Qbus (none of the
3100 series are Q.). The 3100s are basically single board pizza boxes
though there are double height models (3100m20e) with one main board
and several daughter boards to add memory, video planes, IO. They
generally expect SCSI disks. As small vaxen go they are 2.4vups at the
low end and low power up to some fire breathing versions like the m90.

Hello, all:
For those not necessarily following my 6502-based SBC project on my Web
site, here's the latest.
The schematics are done, I just have to make some minor tweaks. Then I
can work on the PCB layout. The board size is now 9"x7", which is way bigger
than I anticipated. There are 20 ICs on the board, most of which are 24, 28,
or 40 pin jobbies.
Anyway, what I'm going to do is make DXF pictures out of them and post
them to my site for all to see. Comments will be welcomed.
Once the design is finalized, I'll have a prototype board made so that I
can see if it works.

*GRRRRRRR!!!* *Dont* Get me started with this! Our MIS department

The only 'StyleWriter' class printer you would get going on your 'Plus
specced' mac, would be either a Stylewriter or Stylewriter II, and would
require at least system 6. :/
You need 68020 mac or better for the color stylewriters.

I forgot about that one (mostly because the power supplies burned up a
lot in them..) They were "Carrera" (68020) CPU boards, with a VME SCSI
board in the second slot.
There are also a bunch of third party 6U VME Sun compatible CPU cards
that were made. Since the application for the system wasn't specified,
it's tough to suggest what type of system is appropriate.

No, neither is is 3/60
The 3/110, 3/150 or 4/110's were in four slot VME chassis. Most of the
rest were in either rack mounted 12 slot desk or rack mount chassis.
I'm rather fond of the 12 slot rack mount chassis, myself. Easy to
work on, with a big power supply. There was also a 7 slot desk side
chassis.
I haven't seen too many VME Sun systems getting thrown away any more,
most of them now are first and second generation Sun 4's.

You are correct, sir. Portland, Oregon, I should have said.
