If you want it to be less painful, buy me a T1 subscription (would have to be

a sync serial card for either VAXBI bus or Q22-bus that can handle it.

Yes, they do.
The VAX8600 was targeted at large IBM sites, so they put in an oversized
power cable and receptacle, that was the same as for the IBM equipment
they planned to replace.
So the 8650 I have here have a cable and receptacle specified for
410V@32A/phase, but it runs just fine on 16A/phase.
And our KL-10 sat on this *huge* 410V@63A/phase thingie. That receptacle
was just large enough to be silly. And the power cable is not something
you carry around in your hand...

I know, I have one, and I used it for my Inet connection when I lived in Dallas
and had a 64 kbit/s DDS line. It's rated for up to 256 kbit/s with one channel
active or 64 kbit/s with both channels active.

Do you have any more details about DSV11 operation above the rated 256 kbit/s?
What exactly is the real limit and what are the limiting factors? I have the
technical description (EK-DSV11-TD), but it isn't absolutely clear.

I'm not using a VAX 7000 (and don't consider it a real VAX thanks to LSB and
whatever else they broke in NVAX+ when they fit it into an Alpha pinout), but
I'm curious why. I mean, how is DSB32 special? I recently searched for DSB32
on Google and came upon a posting by you saying the same thing, there you also
said it had something to do with the way its firmware locked memory. What
exactly is wrong with it? Does it strictly follow the VAXBI spec or was it
given an exception? Does it use IRCI/UWMCI pairs exactly as the spec says or is
it broken? Or is the VAX 7000 kludge the one at fault here in that the memory
is not presented to VAXBI as prescribed by chapter 8 of the VAXBI spec (the
Must Respond Set for Memory Slave), and DSB32 just happens to be the only
device that uses everything that the spec says is allowed? Or will all VAXBI
devices that use BVP (interlocked queues) not work on VAX 7000 because its VAXBI
interface to memory (through XMI and LSB) does not support IRCI and UWMCI?
That would be DSB32, AIE/AIO (DEBNx TK50/TK70/Ethernet), all BI-to-CI adapters,
DWBUA if some UNIBUS device accesses memory with DATIP-DATO (which turn into
IRCI/UWMCI), what else? You said DMB32 should work, I guess it isn't using
interlocked queues. But then again IRCI and UWMCI are the in the Must Respond
Set for memory nodes (section 8.2.2), so it would just mean that VAX 7000 is
not a real VAX as I've been saying all along.
> I suspect that for T1 speeds you'll be stuck using an

Well, neither Alpha nor DECnis firmware run 4.3BSD-Quasijarus, so those are not
my options (I love my 4.3BSD-Quasijarus based router and won't give it up), but
there is one more option: build a new sync serial card! We can even build both
Q22-bus and VAXBI versions.

Ok I'm extremely irked.
Friday afternoon the classiccmp server decided it didn't have a slave drive.
It has done this once or twice before, for some reason the system can't see
the drive anymore so it flags it as non-existent. Usually after a reboot it
goes fine for a few months at least. Most odd. I'm guessing it's the crappy
Western Digital 160gb drive I bought. Don't think I'll be getting any more
Western Digital for a while. It came back up friday afternoon and I saw a
few emails go through the list so I assumed all was well again. Stupid Me.
So I promptly decided to ignore the list for the weekend, had a very full
weekend with lots of other stuff (work & home) to do. Sunday night I noticed
that the list hadn't passed any traffic since friday night. First thing I
checked was the drive, but that was ok. It was a very bizzare odd problem.
Sendmail appeared to be working fine but mailman wasn't queueing any
messages. Both inbound and outbound mail were definitely working though.
Odd - the pid files for mailman were dated in the future, but the system
date was correct (and had been). I tried pretty much every trick I could
think of to no avail. I finally gave up around 1am and said the heck with
it, I needed sleep and have some WorkStuff to take care of. Tonight will
probably be an all nighter due to a different work-related server issue. I
had even tried re-installing mailman 212, figuring a binary got corrupted in
the fiasco friday afternoon. No Joy. Looks like all messages were sent to
the shunt directory, which means a mailman executable failed. Some message
about can't unicode because bytes 0-4 are not cardinal. Ick.
So this morning I upgraded to mailman 2.1.4. That seems to have done the
trick. Pid files are still dated in the future though. What fun.
All appears to be back up and running. I apologize for the extended outtage.
You'll forgive me if I ignore this list for a few days, I just don't want to
think about the server for a bit. It's self-interest, I figure if I stay
away from it for a few days I won't be so ready to unplug it and chuck it
out the 2nd story datacenter window.

hi all,
Eric bought an item that I had on E-bay about 6 weeks ago and I've
emailed several times but I haven't gotten a response. After yesterday's
posting I heard from a friend of his that also hasn't been able to contact
him. Is there anyone in the same area as Eric that can check and find out
what's happened to him?
I had a phone number for him and I just tried calling it and the guy that
answered said that Eric doesn't have that number any longer. It sounded as
if he's gotten a lot of calls for Eric.
Joe
Eric are you out there? If then you need to contact me. I've sent you two
E-mails and haven't gotten a reply.

Hey ya'll... please take a look at these three pictures:
http://geocities.com/lyosnorezel/keyboard1.bmphttp://geocities.com/lyosnorezel/keyboard2.bmphttp://geocities.com/lyosnorezel/keyboard3.bmp
The first two show the keys, the third shows one of two connectors that it apparently interfaces the computer with. The two "plugs" are 8pin jacks... like cat5 but in a wider, more spread out form. The most noteable things about this keyboard are as follows:
Interesting Keys:
Cancel
Move
Help
Action
Over Type
Finish
Copy
Lock
Code (instead of ctrl)
shift + 6 would give you the "cent" or "penny" sign (a "c" with a line though it)
F1, F2, F3, F8, F9, F10 all have lights
Return instead of Enter
1/4 1/2 fraction key... 1/4 is on top... key is next to "P"
Number pad:
GO
Next
Arrow Pad:
Mark
Bound
Anyone know system this keyboard is from? The only markings are from the company "Datapoint Corporation" "Model No. 93-1222-001" "Serial No. 978870"
It's UL and CSA certified. Other then this there are absolutely no markings.

Yes, my connection is a 31200 bps permanently-up circuit-switched
connection (I wouldn't call it dialup as regular dialups don't get Class C NETs
like I have). I have this service because it is the lowest-priced business
Inet service from WorldCom/UUNET (now called MCI). It had to be a *business*
service from them in order for me to get a Class C NET from them, and it had to
be WorldCom as they were the only ones who just gave it to me without charging
me an extra arm and a leg for it. (Also WorldCom was cheaper than all other
business Inet services, though again I only considered business services as
they are the only ones that give full Class C NETs.) Except for being slow
(but that's fair, you get what you pay for), I'm very satisfied with UUNET and
won't switch.

Hi,
If anyone has diagnostic experience with an R80 or RA81, I'd like to
pick your brain a little...
If this is better done off line, email is fine. I suspect not everyone
is interested on how to revive an R80 :-)
(why *I* find it infinitely fascinating is something I'll never understand)
I have an R80 which does not spin up or come ready:
- All of the voltages are good (all the ones I checked anyway).
- The drive belt had come off but I managed to get it back on
- I can't seem to get it into diagnostic mode; the 8 leds' on the
bottom pcb show 0101 0101 (hex 55).
- When it powers up all of the external lights go on and stay on.
- if I reset (click the switch ont the pcb to "R", the lights go
out
- if I then push the run/start it lights and after about 5 seconds
the fault light comes on and run/start goes out.
- if I push the fault light all lights go on and then the right most
one stays on
- push fault again and they all go out (I can then repeat the run/start
sequence)
I'm guessing the above behavior means the micro is operating, but then I
set the rotaries to "FF" and hit 'enter' (i.e. put the toggle to 'E')
the led's don't change at all. The manual says they should flash and
change as a I enter diag mode. I wanted to use diag more to force a
spin up but no joy.
Does the unit have to be connected to a controller to go into diag mode?
I have an RB730 which this connects to. Connecting is does not seem to
really change it's behavior.

I just got a call from a friend of mine who has a number of NOS
Panasonic LDV-1000 Video Disk Players. These are the type that were used
in some of the early video games like Cinamatronics Space Ace. Is there
any interest in them from list members? Apparently the only thing wrong
is that the boxes got damaged but the units themselves are fine. Let me
know via email if you are interested.
After wanting a Commodore 64 SX for such a long time, a kind man
finally gave me one. (it was
the victim of a garage-clean out. I got it back home and it worked fine
for a while. later
that night I was writing basic programs and this strange color washed
over it's little screen
then it went blank.
Cycling power did not restore any picture.
I left it unplugged overnight, (thinking the problem may have been heat
related)
but it's still in the same state this morning.
Any one have any knowledge? Is it really dead? Is there anything I can
do?
A little info can be found here:
www.pdp-11.nl/peripherals/disk/ra81-info.html
According to the table, when the rightmost light [B]
stays on (and the FAULT light of course), it would mean
you have spin-up problems. Did you tension the belt with
the lever at the right-hand side (at least there it is
in an RA81 drive)?
success,

Ive got well over 50 SONY QW5122F tapes brand new still wrapped up. 200/420M
capacity. Not sure what they work on though. .25 cents each.
Also have other QIC80 tapes, but no MC3020 anymore. Inquire for others.

Yes, I think so. Also, there is a transport safety for the heads. It's a
lever on the HDA, which you should turn to unlocked.
Does the R80 have the terminal interface on one card like the RA8x drives
do? If so, plug a terminal in there and talk with the drive. 1200 bps I
think, though it could be 300. 8N1.

Yes, it's the same HDA.

I figure there's pretty much zero chance of this, but thought I'd ask :)
I have an HP 7906 drive that is rackmounted in one of the "newer" style
cream colored rounded edge HP racks. I want to mount it in one of the older
dark grey HP racks. The mounts are completely different. So, I'm looking for
7906 drive rails that go in the older style cabinet. I do have L brackets
that go in the older cabinets, but with 7906 drives it's pretty important to
be able to pull them out a bit and work on the bottom.
Anyone have a set for trade?

Makes sense, I can't think of any reason to require a minimum of two

That's what I thought, but I don't actually have a copy of the
standard, just my well-thumbed copy of Charles Spurgeon's "Ethernet"
book. It says the stripes are 2.5m apart but transceivers can be
placed at 5m or 7.5m or any multiple of 2.5. Well, 2.5 is a multiple
(in the mathematician's sense of 1 x 2.5) so maybe 2.5 is OK.

I can't think of one either. The reason for the 2.5m spacing is that
it's an odd fraction (about 1/19th) of a wavelength, so when you put
taps on the cable, the small reflections caused by the discontinuities
are out of phase and don't tend to be additive.

Idiot! They're OS ROM (R O M) modules for a HP 9835 calculator. They're
totally useless for anything else.
Joe
More:
"The ROMs used in the 9835 are rather unusual. The ROM carriers look
exactly like the ROMs for the HP 9825 but without labels. But instead of
only holding one ROM, each carrier has sockets for four ROMs. The
individual ROMs are small square boxes similar to those used in the HP 85.
The 9835 ROMs come in sets of 1, 2 or 4 individual ROMs and the ROMs can be
mounted in any order in the carrier or in any position in the 9835. The
fourteen operating system ROMs are similarly mounted in a pull out drawer
on the left side of the 9835. Flash! I've just learned that one collector
has a 9835 with ROM drawers that hold six ROMs each instead of four. That's
something that I haven't heard of before. "

Hi,
Does anyone know how much 3-phase power (at say 220v) a KL-10 requires?
I just acquired some commercial space to move my collection into and I
noticed today that there are several 220v 3-phase power drops that I
hadn't noticed previously. I'm kind of hoping that I'll have enough
3-phase to be able to start resurecting my KL-10, but I need to know how
much I need.
Thanks.

I agree, I forgot about that. Oops!

220V 3-phase? Hmm. I think somewhere around 40A per phase should do it.
We ran our KL-10 on 410V 63A/phase, but that was a bit overkill.
But I'm also pretty sure that 410V 16A/phase was not enough.

Any one have thoughts on 9-track tape drive "O" rings?
The O ring on my TS-11 was under compression for some time and appears
to have stretched to the point where it is too large to fit a tape on
the hub. I'm guessing this is a common problem.
I would think these O rings are pretty common. Does anyone have a
source?

IIRC, its also used on the Apple DOS cards. I'd have to go check a cable
to be sure, but I'm pretty sure its 26 pins, in a DA shell (same size
shell as AUI uses)

Hi all,
Recently I found this really cute, but weird-looking thingie. It
seems to be a handheld tool that allowed operators, field engineers
and so on to manually punch a bit of code onto paper tape, or to
modify (patch) an existing tape.
It was made by, or distributed by "Data Processing Accessories"
in the U.K.
Ideas, anyone?

I'm fairly sure it would, and that's what I meant when I mentioned
ribbon cable. Didn't der Mouse suggest that? I have a Newbridge ATM
Route Server which is a Sun chassis mounted in a Newbridge box, and I'm
fairly sure it has a similar arrangement to connect the Sun port to the
panel on the Newbridge case.
I'm a great believer in adhering to standards. Most of the time :-)
In this case the standard says, in effect, "use this cable and this
layout and it's guaranteed to work". It doesn't say it's guaranteed
not to work if you don't :-)

Does anyone know of a source for replacement
lamps for a PDP-8/E console? I have an otherwise
immaculate console board that I would like to
use in its original condition, e.g., w/o an
LED conversion, but one of the bulbs has been
broken, and, at any rate, additional failures
are likely.
Thanks,
Bill
To Whom it May Concern,
I have some old Tandy computer equipment and many secondhand 8" Disks. I have been told that you might be interested? Who are you and what do you do?

Ping!
By a staggering coincidence, the 1800 mentioned (which is mine - Kevin had
been storing it for me) finally showed up at the Corestore today, in a very
large truck! I'll be updating the web page below with more photos tomorrow
night.
A couple of the pics from the article mentioned (I presume the same article)
are at:

If I can get my arse into gear and this thing running, I'll drag it to VCF
East... IPL diagnostics from punched cards, wheeeeeee! :-)

Are you sure? Are you thinking of the same cable that I am?
I just did a quick check, and I found via Google a page that gives the
pinout for the Mac's PC Compatibility Card's cable. It shows it as a 26
pin connector.
I'm no longer at work where my cables are, so I can't physically inspect
them. I thought the connector on the DOS Compatibility card was the same
"physical" connector that is on the PC Compatibility card (although the
cables, and I believe the pinouts are different). Again, I can't
physically check mine, so I can't be 100% sure. Maybe the DOS card
version was different (I know the cable for the DOS card is a 4 headed
cable as it breaks out the joystick via the cable, while the cable for
the PC card is a 3 headed cable with the joystick port residing on the
card itself).
And of course, Apple had a 3rd style card for the Performa 630/640 DOS
model. I haven't really played much with mine of that model, so I don't
know what it has (actually, I seem to recall that it didn't use a
loopback cable at all)
And then there are always the Orange Micro versions, all bets are off
with those. I've never really played with them.
But maybe you are thinking of a different card then I am. Apple also had
an Apple IIe card for the Mac that had a loopback cable. I don't recall
what it has for connectors. And I have no idea what possible cards there
were for the Apple II series, or what possible other similar cards were
for the Mac beyond Apple's, Orange Micro's, and Reply's (which was really
the same as the first Apple card as it was built by Reply and first only
available from Apple, later to be available directly from Reply)
