>You also didn't say what the connector is installed in!
This one in particular doesn't fit in the 10 year rule. Its from an
original iMac. Its the power connector. It looks similar to an ATX
connector, but it is smaller and has more pins.

Yup, I have one side, and I want the other so I can splice in a new power
supply.

I was able to find on it "FoxConn". It was almost completely rubbed off
(or just poorly molded in), so I missed that on the first pass. I did
check FoxConn's web site, and they do seem to have pics of most of their
stuff. It is going to be a royal PITA, but I suspect I will just have to
click thru their online list and hope I find the right one. (On a first
try, I wasn't able to find something that looked right AND had the right
number of pins AND right pitch for the pins).
>If you can't, do the classic hold-a-ruler-up-to-it and take a
>300dpi photo and post it and ak the list to look at it.
If I don't have luck on FoxConn's web site tonight, I'll probably upload
a pic and see if anyone recognizes it.
Otherwise, I may just have to find pins that fit and put them all in
place, then use silicone caulk or hot glue to make my own shell to hold
them in the right alignment.

Is there any reliable place to check what the name of a connector style
is? I have one I am trying to track down so I can purchase a replacement.
But most of the catalogs that sell large assortments of connectors don't
have pictures of each style. That makes it tough to buy the right thing
when you don't know what it is called.
In this case, the connector looks rather like an ATX power plug. Only
physically smaller (but has more pins). I'm sure Mouser will have what I
want, as soon as I find what it is called so I can look it up.
I go thru this on a regular basis, so I didn't know if someone knew of a
web site, or of some dealer who's catalog actually showed pictures of
each style.

I can't find a date on this thing, so it might be off topic, but visually
it sure looks older then 10 years.
I got this from the "it isn't selling so it is now garbage, help
yourself" pile at a garage sale over the weekend. It is labeled as an AVL
Coyote Memory Programmer. Near as I can find, it is a slide projector
dissolve controller. It has 3 wires hanging from it that I'd guess plug
into slide projector remote ports. However, all the slide projectors I
have seen have 5 pin jacks. These cables have the standard 5 pin plug,
but there are an additional 2 pins below it that will prevent them from
being used with any slide projects I have.
It also has two RCA style jacks labeled Play In and Record Out. I'm
taking a guess they are saving and loading any programming you have done.
(There are Memory Save and Memory Load buttons on the keyboard that helps
me draw this conclusion).
Without knowing how to use it, I can't say if it works or not. It powers
on, and in just pressing the buttons, I think some of the keys may not
work. They are pressure pad like keys, and it feels like the top of the
pads is lifting up, so the keys that don't seem to do anything could just
be failing to make contact (or could only work in some combination or
under certain times).
Does anyone know anything about this thing? Any idea where I can locate a
manual? Is there anyone that has been hunting for one of these and would
like it? I'd be interested in playing with it if I can figure out how to
use it and can find slide projectors that work with it, but it isn't
anything that I'd do more than play with, so if there is someone that
would love to have it, I can probably be persuaded to give it away.

Well Tektronix stuff is still finding it's way to me! I went out this
morning and found a Tektronix 7D15 Counter Timer plug-in and a Tektronix
Microlab I in the bottom on a basket of scrap. Does anyone know anything
about the Microlab? I thought it was some kind of digital trainer but found
a referenece on the net,
<http://www.spies.com/~dd/TE/Tillman/Tek7000-Tillman.html>, about it being
used with a special interface board to test Tek 7854 o'scopes (presumably
the digital sections). It's mounted in a blue case similar to those used
for the Tek 83x Communications Analyzers. Once you open the cover there is
a hinged clear plastic cover on the LH side inside. The clear cover has a
square opening that leads to a card slot in the main unit. On the RH side
is a panel with an 8 digit LED display. The left four digits are labeled
"address" and the right four are labeled "data". Below that is a hex
kexpad. There are also four more keys along the RH edge. They are labeled
"reset", "load address", "load data", "inc" and "dec". The sixteen hex keys
also have shifted functions that look like something that would be found on
a digital trainer. One the left side of the case near the rear are two 1/8"
jacks that are labeled "cassette in" and "cassette out". One the right side
of the case near the back are two DB-25 connectors, one labeled "RS-232
terminal" and the other labeled "RS-232 MODEM". I opened the case to check
inside and found that it only has sone circuit board in it. It has a lot of
TTL ICs, some 2114 RAMs, three 6850 UARTs but no CPU! I suppose the CPU is
on the plug-in card (that I don't have :-(
Anybody know anything about these? I couldn't find anything in my '86
Tektronix catalog and only one mention on the net.

Thanks Antonio. My manual is a bit older: TC1251002 Rev E, June, 1983.
I am going to scan it anyway; a request gives me a good reason to pick up
some scanning work after a long idle time. As I said, I will scan in what
the manuals calles "Sections". You/Guy/etc. can download what is relevant
before I remove it from my site (URL follows when it's up).
Now it's time to fill that 8th CD-ROM with FMPS and manuals ...

There are already a few TC02 and TC12 things online (see
vt100.net/manx).
In addition there are some on bitsavers in pdf/emulex.
I also have "TC12/FS (TS11 Compatible) Tape Coupler Technical Manual",
part number "TC1251002 Rev H". I picked this up from somewhere on
the net but I do not remember where (and it does not seem to be
on bitsavers). If it is not still around somewhere, I could
make it available for long enough to get it online somewhere.
Hopefully this might save you some scanning work!

Id love to see the old Plato running again.
Does anyone here know anyone that worked or was involved in Plato

and might be able to get some kinda "emulator" project going off the

Writing up a terminal emulator might not be dramatic but emulating the

This would be totaly wild and while I dont have a lotta time for stuff
like

And if I could find listing of some games I had written, Id go totaly

Seems TELUQ (Tele-Universitee here in Quebec) was very involved in

Hi Guy,
perhaps I can be of some help here.
I've got the original Emulex documentation of the TC12 tape coupler,
and also the TC02 tape coupler. Both boards are quad-sized, the TC12 is
for UNIBUS, the TC02 is for QBUS systems.
To identify if your board is a TC12, I describe what is in manual.
(wished that those pictures were in more manuals, they're great!)
With the four rows of finger contacts right before you, in the middle
of the board, at the left of the center are two DIP switch packages,
and to the left of those are first 2 small IC's followed by 2 big AMD
2901 bit slices. At the opposite of the 4 finger contact rows (which
go into UNIBUS slot positions C,D,E,F) are two 50-pin BERG header
connectors.
If this manual seems to be what you are looking for I can scan it
at 600 dpi. Big file, but when printed gives very good copies!
The contents (briefly): Introduction - General Description - Functional
Description - Packet Processing - Installation - TC12 Option Switches -
Address Selection - Autoconfigure and VMS, RSTS/E and RSX-11M.
See mainecoon for an impression of the scan quality -- they are my work.

Greetings;
I've got a line on a Xerox 9700 COM driver, which appears to be a
double-rack containing a CDC disk, a PDP11/34a, a big magtape and a couple
honkin' great PSUs.
Was wondering if anyone could identify one of the cards in the unit - this
is the list I received from the owner:
M7843 DR11-K Digital I/O
M7856 DL11-W SLU/RTC
M8265 KD11-EA 11/34A Data Paths Module (rep M7265)
M8266 KD11-EA 11/34A Control Module (rep M7266)
M9202 (2 bus) Inverted Jumpered Unibus Cable (M9192 + M9292)
M9031-YX Unibus to 3 3M cables for 11/74?
M9302 Unibus Terminator - Far End
X020 5012180B-P2 Data Path
X030 CDC Disk Controller
X031 -5 VDC regulator
143103843-001 rev B 8x18 (6pop - 4116-20NL) == 96k?
M8013 RL01 Disk Controller 1/2
M8014 RL01 Disk Controller 2/2
M8092 ???
M8200-YB 1-line sync DDCMP microprocessor w/ 1K control ROM (point-to-point, used with M8201)
M8202-YA DMC-11-MA 1-Mbaud integral modem line unit
M9301-YJ M9301 w/ bootstrap for DECnet DMC11, RX01, TU10, ASCII console
I'm not sure where he got the descriptions, probably from some web
resource or maybe even documentation of some description. I'm curious what
the M8092 is, google doesn't return anything remotely related.
Pictures of the 9700, amongst other bits and pieces, can be found here:
http://microfilm.dyndns.org/~wulfcub/CompStuff
The thing also comes with a couple spare CDC disk packs, and he thinks he
can find an RX01 with the necessary disk controller for it too.

Hi Pete
If it is a piece of equipment, have is broken down into
several sub pieces for shipping. You know, remove the power
supply, etc.

A guy on Ebay seems to have a supply of these. The are labelled
"Intercon", but it is clear that they OEMed the boards from DEC and
ground off the DEC markings. These do *not* have sockets -- you
either solder in the chips or your own sockets, maximum 16-pin DIP,
50 parts. Bypass caps are pre-installed at all positions.
He's also got the the smaller double-height boards. I bought a few
of these, and they look OK, although the pins are *not* gold plated
and are less than perfectly pristine. The seller seemed a bit
disorganized, and I had to send an inquiry after waiting a month with
no shipment, though I got an apology and a free extra board for my
trouble.

Hi,
Does anyone have a KDF11-B3 boot rom or any other version which can boot RX33 or an MSCP device on my KDF11-BA. I will pay for that and I will be very thankful since I have not to buy a Eprom programmer to burn the immages.
Greets all,
I?m looking to acquire my first VAX system. I?m a youngin? who?s been cutting his teeth on OpenVMS through HP?s TestDrive program, and would like to have a box of my own.
I?d really like to track down a VAX 4000 unit, preferably a /300 or higher. I?m not too picky about internals, I just need something to get started on (hardware collecting wise).
I?m located in Ottawa, Ontario, Canada, so I?d be looking for a unit located in Eastern USA or Eastern Canada (yes, I know shipping a BA440 will cost me a bit) and someone willing to bubblewrap it :)
If I?m being insane, hoping to have a 120lbs unit shipped, let me know.. Should I be just looking for the cards / drives separately, and try to find the case locally instead?
Thanks,

As I stated earlier, I have cannibalized three HP laserjet series II
printers. In looking over the parts recovered I find that I have three
(3) totally different memory boards.
The first is populated with small chips on BOTH sides of the board with
a total of 128 soldered in chips that appear from their part numbers to
be 256K memory chips, That is the number 256 appears within the part
number. Now I don't know how wide the buss is but I am assuming 8 bits
because of its age. If so this board is a 4 Megabyte memory board.
The second is only half populated with 16 soldered in chips on one side
that have the number 1000 in their part number so I am assuming they are
1meg chips and using the afore mentioned logic I come up with a
2Megabyte memory board.
The third is fully populated with 32 socketed chips with the number 1000
in their part number and that works out to a 4 Megabyte memory board.
Is my logic sound?
Do I have two 4 meg boards and a 2 meg board?
What is the largest memory board the Series 2 could hold?
I am assuming that the socketed memory is best because it is easily
repaired, but are there any problems with the socketed memory having bad
contacts after time?

1/ query the whois of the according registrar. Example : for .com :
www.internic.net, for .org, www.pir.org. For countries query their NIC
(Network information center), www.nic.fr for France for example.
If you prefer something easier : http://www.whois-search.com/ which
will automagically query the correct whois database.
2/ A web server is bound to an IP address. You can find who owns this
IP by querying another set of databases. Start from the ARIN database
at www.arin.net which might redirect you to some other databases (RIPE
for Europe, APNIC for Asiac/Pacific, LACNIC etc.).
http://www.whois-search.com/ will work in both cases. To have the name

Hi all,
finally, I've had some time and a new scanner to scan in the boards.
Somebody asked me to do so several months ago.
There are scans of one of the two memory boards, the peripherals board
and the CPU board.
Problem is, that I haven't got a website to put them on.
Six pictures are available, size is 500kb - 800kb. They're big, I know,
but everything can be seen, including the inscriptions of the chips.
If anybody wants them, I can send them via email.
Better would be a place to put them online for a week or so. Maybe
a kind person could help me ?
It would be great if someone who owns a C8000/c8002 could check out the
DIP switch settings of the boards. I'm not sure if they're ok.
Remeber, my C8002 doesn't work, I'm trying to fix it.
Have a nice weekend

Hi all,
We've got an M9312 boot / terminator board in our Decsystem 570 (which
has 11/70 internals). The board has four spade connection points on it -
TP1 - TP4. Now, TP1 has a couple of wires connected to it, one white and
one clear, and TP2 has a black wire connected to it. These appear to run
up to the central pillar of the rack - I expect to the 'initialize'
switch. (TP1 is boot input, with TP2 as return, whilst TP4 is enable
boot with TP3 as return)
TP3 and TP4 are currently unconnected. *However*, we have a crate of
memory in the machine in a box labelled MK11-C2. From this there's a
cable dangling out the back, with a pair of spade connectors at the end
(one spade having both white and black wires running to it, the other
having clear).
I suspect this is supposed to plug into TP3 and TP4 on the M9312 board,
but can anyone confirm this? What does the cable actually do? I'm
guessing it's some sort of 'power good' type of signal back to the
CPU...
And whilst I'm here...
We have three H775D battery modules for the machine. The back of the
MK11-C2 has an 8 pin connector marked as being for such a battery unit -
anyone know if the cable's a straight through between the memory crate
and the battery unit? (i.e. 1-1, 2-2 etc.)
I suspect the other two battery units were spares - but the MK11 also
has two more unlabelled 8 pin connectors; are these important for
anything? Will the memory unit be happy without any battery unit(s)
plugged in?
Also... :-) What do J1 and J2 do on the back of the MK11? Currently
pins 1-3 on J2 are shorted via a small plug, whilst J1 has nothing
connected to it.
As mentioned in a previous email, the machine power supplies look good,
but whilst various LED's on the CPU front panel are lit, with the key
inserted we're still unable to use any front panel switches to yield any
signs of life. My *guess* is that the cable hanging out of the memory
crate should be plugged into the M9312, and the system isn't starting
because it thinks the memory crate is upset - but I could be totally
wrong on that and something else is up with the CPU...
And if anyone has any answers in the next 12 hours, then great - as I
can spend all day tomorrow screwing around with the machine then :-)
cheers
Jules

For the people looking for an EMS ROM for the Series 80, this
is the next best thing, the programmable ROM drawer allows you to
install ROM images on 4K-byte 2732 or 8K 2764 EPROMs.
You can get the images from www.series80.org
Note, I am not the one selling this item, I am just posting this
because people have been asking me about the EMS ROM.

Hi
I've found that it depends on the paper that was used and
how well it was fused. Porous paper seems to work better
( non-glossy ) and lighter amounts of toner also works
better than heavy amounts. Too thick a layer of toner
doesn't fuse well to the paper.

Hi Phil
Check for your self. Use a magnet. If it sticks, it is steel inside,
if not, it is copper. At a previous company I worked at, we always
trimmed the leads of IC's and passives. I would say that about 75%
of the IC leads would stick to a magnet and some 20% of the passive
leads would also stick.

Hello, all:
Here's another stumper. I was able to get copies of some of the
Cromemco paper tape software, particularly Space War, so I can test it with
a Dazzler add-on for the Altair32 emulator.
Can anyone with Cromemco experience tell me what loader should be
used to load this software into a machine? I don't recall seeing anything in
the manual that revealed this secret.
Thanks.

Your copies get a little sticky at warmer days, and the pressure inside

I guess that you are right when you say that *any* batteries cause
corrosion over time. I never saw batteries made of *one* piece of metal
enclosure. There must be some opening in that case to get the two poles
(as wires) to the outside world. Et voil?: there you have the weak spot
that eventually will cause a leak!
BTW an other place toi check for leaky batteries are DECstations and
VAXstations (or ...servers). They also have a NiCad (!!!!) "on board".

Pinball machines often have this problem. Cleaning with
just soap and water is not enough. Most current day batteries
use an alkaline electrolyte. This will continue to do damage
unless neutralized. On boards for pinball machine, using
vinegar seems to do the trick. We first soak the board in
a bath of 50% white distilled vinegar for several hours and
then use a stiff brush to remove as much of the corrosion
deposits as one can. Do note that you may need to remove
things like dip switches, relays and keypad covers (
think in terms of where water can hide ). Also, any
socket that is even slightly suspect will need to be replaced.
After the soak, use a water hose and spray rinse the board
well. Shake of excess water and rinse again. Dry quickly
in a warm place. I often set them in the sun but for winter
drying, an oven set to about 140-150F works well. Use
a cookie pan or piece of foil to block direct heat radiation
>from the heating elements ( not a problem in convection
ovens. Also don't even think of using a microwave! ).
Any trace that is rotted through will need to be replaced.

Hi
This is really bad stuff. One of the things I've seen with mouse
piss is that the legs of many IC's are steel cores with tin plating.
I've seen where the IC leg will look fiine but the entire insides
are rotted out from mouse piss. The lead would just crumble
when squeezed with needle nose pliers. I have in the past
assumed this was acid damage and use baking soda solution
and rinse. It seems to help but usually by the time I notice
it, the damage is already done.
I live in the mountains and critters are just part of living
here. Still, I wouldn't trade it for living in any city I know of.

It's now my habit to clean all such cables with white spirit (light
kerosene) or turpentine substitute to remove the icky remains.

Ditto for photocopies. It's the same problem as the power cable vs
expanded polystyrene, actually. Plasticisers in the PVC migrate into
the polystyrene or toner (which is plastic). A sheet of acetate film,
such as is used to make overhead projector transparencies (viewgraphs)
makes a moderately effective barrier.

Hello, all:
Putting any Windows jokes aside, I'm looking for a decent
Win32-based FTP server program to use at home to move files from my weather
station computer to an Apache Web server which is also at home. The goal
here is to open a single port in the firewall so I can log in and see the
weather at my house.
Not being familiar with Apache, maybe there's a way to do this
without an FTP server, but I need to move a text-based data file every 5
minutes from the weather station program to the http server, both of which
presently will reside on the same PC. The weather program handles all
aspects of creating the data file periodically and will upload the data
using ftp -- it does not provide for direct copying of files, the assumption
being that this data is being uploaded to a server that's not on the same
physical machine.
I wanted to get some recommendations/user's favorites before I start
Googling.
Thanks.

Without looking at the boards, it's impossible to tell for certain.
Some 11/73s were upgraded without changing the badges on the front.
*Usually* a microPDP-11/73 is in a BA23 and a microPDP-11/83 is in a
BA123, but not always. The real difference is in the use of normal
QBus versus PMI memory; that makes more difference to the speed than
just about anything else. Originally, an 11/73 would have had a 15MHz
KDJ11 and an 11/83 would have been 18MHz, so they'd have had slightly
different suffixes on the M-numbers, and they'd have slightly different
boot ROMs, but any of these things may have been changed. What an OS
goes by is whether the memory is PMI or not.

Correct.
I have an 11/84 in 10.5" box (console at the right-hand side)
and one 11/83 in 5.25" box (console in the middle of the front).
The original poster is maybe not so "DEC-aware", but then again,
I often doubt my DEC knowledge too.
How much difference is obvious in just a glance at an 11/73 and
an 11/83?

So, my guess, it is probably an "11/83".
The 11/83 QBUS CPU board plus memory on QBUS side, then the
QBUS-UNIBUS bridge and the rest is UNIBUS with its famous
line of (beautiful) peripherals.
