Hi,
I started to revive an old Micro PDP11/83 I have for over 12 years
now. It is fully assembled and last time I tried to start the
machine it some kind of started.
My biggest issue at the moment is the power supply.
After the machine is running for a while, let's say 10 minutes and
then when I poweroff, the power supply starts producing a lot of
dense smoke. The smell is very penetrant.
What can I do with the power supply? Do I need to exchange it
completely or just parts of it?
At the moment I removed it from the case like described here:
http://www.bitsavers.org/pdf/dec/pdp11/microPDP11/EK-MIC11-TM-002_MicroPDP1…
Thanks in advance for any starting hints,
Waldemar
Greetings!
A friend of mine got a aox double time 16 board into a mac SE
Unfortunately it isn't working (not accelerating the mac) and we're unable

So I notice that M8120 controller card for the MS11 seems to share its etch
with the earlier M8110 variant (the M8120 says "M8110" in the etch :-); so the
differences must be component/configuration/ECO. Does anyone happen to know
what the differences between the two are? Thanks!

All,
Per the recent discussion on thicknet/early Ethernet, I figured I'd see if
there's any interest in cut-to-length Belden thicknet/10base5 Ethernet
cable. I've got a local surplus guy who's got at least one 1100 foot roll.
It's the real Ethernet spec stuff, sez so on the cable, and it has the
bands to locate your vampire taps.
If there's enough interest, I'll buy the spool off of him and cut it to
length for whoever's interested in buying some. I can crimp N terminations
on as well.
Thanks,
Jonathan
I ran across the following messages in comp.os.os2.marketplace
(referenced from comp.os.os2.programmer.misc) and remembered that there
were a few people talking about IBM's Personal Communications Manger
here, particularly in the context of the P/390. So I figured that I'd
cross post the info. The asking price (free + S&H) seems reasonable.)

Like I said, they will come pick things up, as they sit - perfect for Pete's
situation. And from my experience, not _always_ cheap, but _usually_ pretty
good (e.g. a large PDP-11 in a 19" rack from Toronto to Virginia was about
$500, which for international freight on something that big is pretty good.)

Al uploaded some of my Tennecomp docs onto Bitsavers:
http://bitsavers.org/pdf/tennecomp/
He also already had some brochures, which are very interesting as well.
Anyone else have some Tennecomp stuff? I've got more stuff to scan,
including a bunch of schematics (size C paper, for the most part), as well
as a few other manuals I believe.
I'd be curious to hear any of their history, especially because of their
location in Oak Ridge, TN.
I will also photograph some of my Tennecomp things (my Minidek, some
Omnibus boards, etc.) at some point.
Thanks,
Kyle
P.S. My Minidek came with some carts, but the pressure pads are all rotted.
A cursory glance online didn't turn up any source of replacement pads in
stock for Fidelipacs/Stereo-Paks. Anyone have any suggestions, or tips on
making your own?
I've been doing some sorting looking for some boards for a list member, and
found a few items I will probably never use. Shipping from 61820, and
overseas upon request. Stateside shipping is $16 for as many hex or quad
height boards as you want, and $11 for as many quads as you want.
Looking for offers, the more you want, the better.

Re: HP Series 9000 early 1980?s computer hardware
Hi,
I own several HP 9020 work stations along with peripheral gear
associated with that series. That gear includes several types of hard
drives and tape drives, standalone monitors and even an impact 132
character line printer. I also have a CPU, that I think is a 9000/550.
Not a work station but a more powerful CPU using the same technology as
the 9000/520. Plus cables and extra circuit boards used in that series
equipment. All of the stuff worked the last time it was fired up. I also
have the disks and tapes for the software shipped with that equipment.
I am getting along in years and rather leaving it to be trashed in the
future I am looking for a new home for the stuff. So can you suggest
someone who might be interested in it?
Sincerely,
Charles D. Parker

I've gotten a copy of this Forth from someplace. I was going to play with it some but it has so many non-standard words, I ws hoping someone might have glossary of words for this Forth. Also, it came with a number of game programs that used some graphics output. I was wondering which graphics board it was intended to work with.

Visited an older collector recently, and in his shed he has a strange thing, labeled CDC, that somehow looks like a drum memory, but then again not ( drum looks too small to be usefull )
The controller that goes with is? a transistor based? monster on countless small pluginboards.

Hi,
I just found a Kaypro 2000 at the local recycler. No power supply.
From what I can find online it has three(3) lead acid batteries. Any
thoughts on getting it to fire up? I do not know the polarity of the
power jack on the back. Once I get that, I was thinking of a 6 volt
supply, more to just turn it on, rather than try to charge the
batteries. Thanks. Joe Heck
I was fortunate enough to acquire a TU56 this week, along with a TD8E
controller.? However, the TU56 lacks the G888 flip-chips necessary to
work with the TD8E; I know these parts are in short supply, but in the
unlikely event that anyone has (a) a set of 5 G888 boards, or (b) a
TC01, TC08 or TC11 DECtape controller in any condition that they would
be interested in selling/trading for, please drop me a line.
Thanks as always!

I haven't gotten this all together yet, but thought I'd let people here
know first that I have a PDP-11/23 for sale!
I'm just trying to clean things out, and have decided to focus my
collection a bit. I need to go down and inventory everything, but I have a
PDP-11/23 with 64KW of memory (not sure on what boards I have to give it
that yet).
The machine itself works, thanks to some help from people on this list. I
have not gotten around to getting the RL02 working, though I have the
interface and what I believe is the proper cabling. It's a pretty clean
drive, and does power on just fine.
I boot the 11 via a TU-58 emulator, so other than the RL02 I don't have any
physical drives or tapes.
Not sure on the price yet, but thought I'd see if anyone is interested.
Ideally this would be for pickup in Des Moines, Iowa.
Thanks!

I have a similar problem. Has anyone re-engineered the G888?
I have 4 AS/400s free to a good home.
One is an S20, one is an 820, and 2 are 730. I also have several extra various cards, CRT consoles, cables, etc. for them.

Folks,
Just to say I did end up doing a re-install of OS/2 on a smaller drive, which took most of today, but the P390 software is now installed and I have loaded VM/CMS and IPL'd a simple 3-pack system copied from Hercules. The readme that comes with the P/390 V2.5 software explains how to set up the systems so PCOMMS can talk to it. I still don't have the screen resolution working at 1024 x 768 which the manual says it should. Oh and PMVNC also runs so I can remote control the beast. It was all a bit of a slog, mostly because OS/2 is a bit of a slog. The P/390 was the easy part.
Thanks to all who helped,
Dave
I don't see a manual for the HP 12661A DVS (Digital Voltage Source)
interface card on bitsavers, or hpmuseum.net, or anywhere else.
The only reference I have found is in a list of not scanned manuals here:
http://rikers.org/hp2100/jeff/iocards/iocards2.txt
---------- 12661 DIG VOLT SOURCE ----------
MANUAL FOR DIGITAL VOLTAGE SOURCE PROGRAMMER
INTERFACE KIT HP 12661A
MANUAL NO. 12661-90004
APRIL 1971
[Cards #12661-6001 and 12661-6002, connector 02116-6178]
This is the interface card that would be used in an HP 1000 to control
an HP 6130A Digital Voltage Source. See Hewlett-Packard Journal, June
1968.
There is the 14902A BCS driver as listed in
5950-9226_HP_Software_Catalog_Aug1973.pdf
Source code for that driver is available as 14902-80001_Rev-A.src in
the bitsavers HP_1000_software_collection Master Files, Type 4.
Mainly just curious because I have a couple of HP 12661A interface
cards without manuals that I have never tried to use and I was
reminded about them when an HP 6130A made a brief appearance in Marc's
latest Weird Stuff video.

Any Zenith Z-90 owners out there (which appears to be the same thing as a
Z-89 / Heath H89, but with a DD soft-sectored disk controller)?
I was given one up a couple of days ago which isn't giving the expected
"H:" prompt at power-on - but it *does* give a blinking cursor, and hitting
off-line lets me type, and characters get echoed to the screen.
Right-shift-reset clears the screen and gets me back to the cursor.
Before I dig deeper, I'd like to verify that this isn't a feature, i.e.
that it's not auto-magically dropping into "terminal mode" at startup :-)
Unfortunately while I have masses of documentation for the machine, I'm
lacking a basic user guide which might shed light on any such mode; some of
the more detailed documentation that I have talks about rerouting the port
cabling to use the system purely as a terminal, but doesn't mention doing
any other configuration.

So I've just realized that the KB11-B (the earlier -11/70 CPU, the KB11-C
being the later) FMPS is not online; I couldn't find them (but then my
Google-fu is notoriously weak, q.v. the Motorola 4015 - thanks all, BTW), but
Manx also says:
http://manx-docs.org/details.php/1,9214
they aren't available.
So, I have a set (got it not too long ago on eBait). Does anyone need these?
Only my 8x11 scanner has auto-feed, so I'm not up to doing the whole thing,
but I'm prepared to go through and scan the things that are different from the
KB11-C (the prints for which _are_ available); the M8133 and M8138, and
whatever else is different (flow diagrams, etc).

Folks,
I am rebuilding a Microchannel server with a P/390 card. It must have come
with a licence for OS/2 Communications Manager as its required to get the
P390 working but despite having several boxes of CDs and Floppy Disks I
can't find a copy of this software anywhere. If anyone has a copy of CM 2.11
they are not using and would be prepared to sell me., I would be pleased to
pay for it.

Drums were used as main memory in a number of early computers, and as secondary memory for a while longer. I wonder how fast real ones (actually constructed) managed to be.
What prompted this question is reading an interesting document: https://ir.cwi.nl/pub/9603 (in Dutch), "Principles of electronic calculating machines, course notes February 1948" by Prof. A. van Wijngaarden at the Mathematical Center (now CWI) in Amsterdam. It's quite a fascinating short introduction into computing technology of that era. (One comment in the intro: "The field is new. At the moment, the Eniac is the only working machine..." -- probably not quite accurate given some classified machines, but not too far wrong.)
The section on main memory describes a bunch of different technoly possibilities, one of them drum memory. He writes that a drum of 8 cm diameter (a bit over 3 inches) and "a couple of decimeters height" could hold maybe 100k bits, with a track pitch of "a few millimeters". So far so good. He goes on to suggest that such a drum might spin at 1000 revolutions per second, i.e., 60,000 rpm. That seems amazingly high. I could see it being physically possible for a drum of only 40 mm radius, but it sure doesn't sound easy. It's a good goal to strive for given that the logic, even in the days of vacuum tubes, can run at cycle times of just a couple of microseconds. As one more way to speed things up he suggests having multiple rows of read/write heads, where the addressed word would be picked up by whichever head sees it soonest. 10 rows and 60k rpm would give you 50 microseconds average access time which "even for a parallel computer would be a very attractive number". (Pages 17-18)
I'm wondering what the reality of fast drum memories looked like, and whether anyone came even close to these numbers. Also, am I right in thinking they are at least in principle achievable? I know I could run the stress numbers, but haven't done so.

Hey, all, the RK11-D contoller for the PDP-11 uses Motorola 4015 MSI chips on
one of the boards (M7254), but I can't find out anything about them. Google
didn't turn anything up, and the appendix in the RK11-D Maintenance Manual
that has info about 'all' the MSI chips used in the RK11-D doesn't have this
one. It appears to be a quad flop - anyone have more info? Thanks!
Noel

Actually, since they buy 'in bulk' from carriers, they are surprisingly
reasonable; their quote to ship an H960 rack from Arizona to me was less
than I was quoted by some carriers.

Pakmail can _send_ to most countries (they can only do _pickups_ in the US
and Canada, that I know of), but of course sending a large object a long way
can be expensive. I don't know if they can do surface (i.e. boat) to
destinations outside North America, or just air - check their Web-site.

I Am Not An Engineer(tm) but it seems to me that a taller cylinder
should be less prone to wobbling on its axis than a flat disk,
particularly if it's built at the scale of the drums I've seen at the
CHM where there's room enough to really bolt that sucker down. Bit
different than a 3.5" box with a stack of thin metal platters in it,
I'd think.
I wonder how the late generation paging disks (fixed head per track) like DG used in the 80's compared?

Back in the 1970s and 80s, my brother and I used to frequent computer
swap meets in and around Orange County, CA. We both built S-100 systems

kept at it for several more years. Last December he passed away, and I
discovered that he had kept his "big" system, and had put together a
second as well.
I'm interested to know people's thoughts on what they might be worth,
both as complete systems, which I would prefer, and if sold as
individual components. Everything is located in Santa Ana, CA.
My brother was a fan of OASIS, so his main machine was switch-selectable
to boot either that or CP/M (MP/M). It was almost certainly running when
it was decommissioned (which would have been at least 20 years ago).

I'm experimenting with setting up UUCP and Usenet on a cluster of 3B2/400s, and I've quickly discovered that while it's trivial to find old source code for Usenet (B News and C News), it's virtually impossible to find source code for old news *readers*.
I'm looking especially for nn, which was my go-to at the time. The oldest version I've found so far is nn 6.4, which is too big to compile on a 3B2/400. If I could get my hands on 6.1 or earlier, I think I'd have a good chance.
I also found that trn 3.6 from 1994 works well enough, though it is fairly bloated. Earlier versions of that might be better.
Does anyone have better Google-fu than I do? Or perhaps you've got earlier sources squirreled away?
As an aside: If you were active on Usenet in 1989, what software were you using?

EISA is a nice-to-have, especially if you want to run multiple
interfaces (much better irq handling than ISA) and/or higher speed
stuff like FDDI, 100Mb enet, T-3/ATM, etc. Or you already have a
cache of EISA cards. That said (and this is x86 specific, because
there's a whole HPPA EISA world I don't know a lot about with all
sorts of weird stuff):
1) PCI does a better job......usually.
2) EISA motherboards, desktop machines and fun/exotic network cards
seem to be getting increasingly rare and ridiculously expensive, at
least on evil auction sites. On the other hand, 10Mb EISA ethernet
and scsi cards are chump change.
3) There are some interesting network things that just don't seem to
have ever been made for EISA. For example, I've never heard of a fibre
ethernet or HSSI card for EISA.
4) I think EISA limits you to 386 through PII CPUs (and probably PII
as a PPro Overdrive upgrade outside of a server class machine). At
least, I can't think of a P3 machine with EISA. YMMV.
5) The video card options are a bit thin on EISA. The Compaq QVision
VGA is common as dirt (and just as dumb), but outside of that the ELSA
Winner and ATI Mach32 are the only "real" graphics cards I seem to see
often. There's probably some awful TIGA boards out there somewhere.
Go PCI.
I held on to a couple of Intel Xpress machines for the EISA bus. I
doubt I'd pay the premium over a solid PCI/ISA machine.

Yeah, but didn't the GX (and KX) have some pretty serious bugs until
really late steppings? Same to a lesser extent with the NX. The BX
(and FX) however was very reliable, as I recall.

Yeah, me too. Great chip with a long useful life. I ran a couple of
Intel PR440FX based machine for years past their expiration date
because they kept up with the load and just wouldn't die.

ALR Revolution server, probably. NCR and Corollary made 8-ways.

Great machine; built like a tank. Much better quality than the
Xpress. I had an XL 6200 (200Mhz PPro) for many years and still
regret getting rid of it. Lucky you you got yours back. The HP Vectra
XU was also pretty nice.
Hello Folks.

P.S. If you're waiting on something from me, know that I have not forgotten
about you, just took most of the last month to setup and plant the garden.
I am getting back up to speed and will respond to everyone and pick up
where we left off promptly, but feel free to nudge me if you somehow fall
through the cracks and are neglected. Forgive me, and please know it is
not intentional.
