I have a Versatec interface here somewhere, but I don't remember if it is
for an 8 or 11.

[cctalk] Re: DEC VT340/330 ROM Cartridge

[Paul Anderson via cctalk]

I believe the VT340-A has the ROM card, but the VT340-G (or plus) does not.
The same goes for the VT330A, B, and C versus the D, E, and F.

A quick update: The seller and I have not been able to reach a deal on any
of this. He is looking for ebay or higher prices, and nothing is complete.
It appears it is bits and pieces leftover from scrapping years ago.

I haven't looked at this in a long time, but I believe the H742 "bulk power
supply" puts out a voltage to the regulators to convert to the required
voltages. I don't remember what the voltage is.

The DD11-PK is used only on the 11/04 and 11/34.

The 11/05 had 4 dedicated backplanes to use. Pick the one you want to match

Yes, I remember and I'm doing ok thanks. I hope all is well with you.

If you send me the board part number and the chip number I should be able
to find you the part number.

In UNI-BUS, I have MOS and core sets plus most options.

I can't take everything with me, and whatever doesn't sell at VCFMW can be

PDP-8A parts including backplanes, most CPU boards, 128K, MM board MM8-AA/AB
8-E boxes and boards
DECMATE Rainbow, and PRO systems and parts
A few 11/05, 11/10 boxes
a new 54-21149 KN15 cpu

Tape drive heads
LA36, LA120, and other printers and parts
various VTs and monitors and parts
MFM and floppy drives
Qbus boxes and hundreds of boards
1000s of DEC boards and parts
possible a few 3000 and 5000 boxes and parts

If anyone wants to stop by and look for things, please contact me off list

quite a lot of DEC items.

If you have any questions contact me off list.

[cctalk] vcfmw

[Paul Anderson via cctalk]

 If anyone wants any DEC gear brought up to wcfmw, please contact me off
list.

If anyone is driving out from the NJ area, I have a few pieces of audio
equipment I need to get transported to IL.

I also collect US and foreign coins and currency, and am interested in
buying or trading for DEC items.

Thanks, Paul

[cctalk] VCFMW DEC and other gear

[Paul Anderson via cctalk]

If all goes well I will be driving up to WCFMW on Friday, Sep 9th, with a
van loaded with DEC and PC items.

If you are interested in any DEC gear, please contact me as early as
possible so I can get it loaded.

If you want to stop here on your way to or from VCFMW, please contact me
ASAP to set up a day and time. I am located about 12 miles west of
Champaign, IL ( I-57, I-74), which is about 2 1/2 or 3 hours south of WCFMW.

If anyone is interested in DEC chips, I will be taking offers on several
DEC boards (M7819, DZ11 and M8044, MSV11-DD come to mind- I have dozens of
each) with the gold fingers cut off. I hate to do this, and you might hate
it too, but I have a lot of stuff sitting here for years that need to go. I
also have an assortment of several thousand unused ECL chips.

Please contact me off list if you have any interest or questions. If you
wish to talk, I will gladly give you my phone # off list.

Thanks, Paul

MG10 parts

[Paul Anderson via cctalk]

While moving some things around I found the following:

7  M8588
6  M8591
6  M8592
4  M8593
14 M8594

All appear to be NOS.

I also found :
G103
G222
G223
M911

Which I did not count, and they seem to be memory related, but I
haven't checked to see which memory they are from. If you have any interest

vcfmw

[Paul Anderson via cctalk]

Due to health problems I won't be able to attend vcfmw this year.

I live just outside Champaign, IL, I-57 & I-74, about 2 hours south of
I-80, and 2 hours west of INDY. If anyone is interested in l buying
anything I should be home a few days before, during and after WCFMW.

Please email me with the time and day you would like to stop, and what you
are interested in seeing/buying.

I hoped to hang on to most things for a while, but I'm afraid I'm going to
start letting loose more and more.

Thanks, Paul

Re: Fwd: Crypto AG

[Paul Anderson via cctalk]

I started this with good intentions, and I thought the post was on topic. I
did not want to start any
political arguments, or any arguments for that matter. In my opinion, the
intelligence community
is the Real World. Few citizens, in most countries, have little idea what
happens in the military, and
even less of the intelligence community.

My father, who was a 1st Sgt in the 28 Div, was also in the Bulge. D-Day
was very tough on the 101st.
They deserve a lot of credit and respect, and have a remarkable history.

Hi Jos,

True, but I don't talk about information that may still classified. If it's
already in the media, it's fair game.

I pretty much agree with everyone. It's been a few years, but I'm 98+% sure

Re: RX01 wants

[Paul Anderson via cctalk]

I think you mean RX11.  I'll see if I have any I can spare. Isn't the
BC05L-15 folded up in the case?
Or did they put a short one to the back of the box?  I can't remember now.

There are 3 or so screws on on each side that hold the bottom of the box
on. The same screw
 and holes are used for the slides. I'll look for slides also. Which are
you on located?I know
someone who was looking for a box last year.

Are they the old Calcomp cast aluminum, or the newer DEC 70 class drives?
The DEC ones
can sometimes be converted to RX02s. I think the older (RX01 only) were the
M7726 and M7727.
The newer RX02 boards, M7744 and M7745, can be used for either.
DISCLAIMER!! I'm taking
the board numbers off the top of my head. They could be wrong.

I pulled some RA60, R80, R81, etc. prints and manuals earlier, but left
them in the basement when I came upstairs.I will bring them up tomorrow and
put out a list.

Hi Mattis,

I think It's PDP-14 stuff also.  I'd be interested in trading for it  to

Off topic- precision tooling

[Paul Anderson via cctalk]

I have a sizable quantity or tooling for sale or trade including :

circular blades, mostly Levin, 1 1/4 d, 1/4 arbor from .008 to 03 and
probably others.

drill bits- Levin. 13mm, .0028" etc.and 15 tubes only some labeled, B & D,
Cleveland decimal sets, Precision twist and other companies sizes 60
through over 100 or so..

Morris taps and dies, 0-80 through -160, about 20 sizes.

Most are new, but a few might be used.

If you have any interest, contact me off list.

If there enough interest I'll try to make a detailed list. They
 are a pain for me to work with, but cheap to ship.

I also have larger size taps, die , and bits up to 1 1/2 or so, I think a
#3 or #4 Morse taper

We had a DG ROLM at my last base. Not Navy, but USAF. I don't remember

sure why we needed a ruggedised computer next to a potato field.

VCFMW drop offs and visits

[Paul Anderson via cctalk]

If anyone going to VCFMW needs any (mosyly) DEC items dropped off there
please let me know so I can plan ahead. Trades are sometimes workable for
other DEC equipment, even more so for US and foreign coins and currency.
I plan on arriving Friday afternoon and returning Saturday night.

If anyone wants to stop by and look around, please let me know of tentative
plans so I can plan accordingly and not have too many people tripping over
each other.

Please contact me off list.

Thanks, Paul

VCFMW

[Paul Anderson via cctalk]

If anyone from the UK is coming over to VCFMW and would be willing to bring
me some nice crisp uncirculated currency I will be happy to trade you for
US currency or DEC computer items. I can make up a list over the next few
days. I don't know when the new 50 is coming out, and I'm also interested
in the Steven Hawkins coin, coins from the isles, pre-decimal and other
foreign coins.

Please feel free to contact me off list.

to contact me off list.

I would prefer to sell in qty, but will consider all requests. If you are
parting them out and don't want them, I will reduce the price and keep the
fingers.

The banks I go to usually have a pretty good selection.  Every once in a

If the note is in good condition, I'll buy it from you. I've been
collecting US coins on and off for years, and started on GB coinage when I
lived over there. Now I collect about everything, including currency, AND

PDP 11/15

I bought a large package of DEC gear last year and it came with a PDP
11/15. I have no need for this classic, and put it on the list. A few
people responded, but because of my problems, I never followed up with
them.

For those who responded, I apologize for dropping the ball. If anyone is
interested in it, please contact me off list.

BTW, I have started on pulling a few things out of the warehouse.

I missed the part of the thread about the memory being disabled. I think
the 11/05/10 is the only PDP-11 with a few registers on the CPU that you

Re: "industrial" PDP-11

I knew customers who were required to put their systems in environmental
cabs, which had special filters and AC. I don't think DEC ever made any.

They did make the RT100, RT340, etc. which were rugidized  versions or the
VTs.

The standard 8s and 11s pretty much became "Industrial" when they were

Industrial 8s and 11s. Like Al said, that part was just a change to red and

Re: Looking for DEC M7264-CB Troubleshooting Documentation

[Paul Anderson via cctalk]

If you are running a BA11-M box (3 1/2 inches tall), make sure the 2 fans
are running up to  speed. They slow as the fans go bad and can cause all
kinds of H780 power supply  and logic problems. When you shut the box the
fans should spin for a few seconds. If they stop within a second, change it.

Hi Eugene,

I found my Emulex boards, but found TU13s and not QT13s. I did not look at

Then I found a few Cipher Data Products ( AKA Spectra Logic Products)

with different handles.

Did Dilog or anyone else make anything else that would work?
