I'm not making a lot of progress, was using my time to fix the Citroen DS
replacing thegearbox in it and overhauling the steering cylinder and fixing
a lot of little items which you encounter when working on a 44 year old car.
It's a little like classic computing, if you don't touch it everything keeps
working, but if ....etc.
Citroen used a rubber based wire insulation for the DS and Pallas models
between 1965 and 1968.
This kind of insulation hardens over time and corrodes the copper wires, in
the Safari I have, this wiring isn't used for the main wiring harness (lucky
me:-) but they used it for smaller components like the wiper engine wiring
and ignition resistor wiring etc..
Real fun and lots of fuses ;-)
To come back to the HP 9830 I did find some time to connect the LA to the
datapath board and look at the Carry and ALU signals
The carry doesn't change while the processor is running it's test cycle, the
QC and AC lines seems to be consistent to the processor state. So I think I
have to look at the timing of U12B and at the BCD mode X2.
I'll get it running .. some day

This thread begs the perennial question: What is the status of Mentec
Inc? Who owns rights to the PDP-11 and the Digital Equipment operating
system for that architecture?
Some on the list have acknowledged PDP-11 related contact with Mentec
in the recent past. If I was a licensed user of RT-11 and I wanted to
change the terms of the license, how would I do that?
I have no direct knowledge of Mentec so I did some online searching,
below are my results.

The building at:
13 Hampshire Drive
Hudson, NH 03051
It is half occupied and the rest is available for rent. At least part
of the address is a printing company.
I have about a dozen boxes of fan fold paper.
Most are 9 1/2" by 11". The sides with the holes
for the sprockets tear off leaving a clean sheet
of 8 1/2" by 11".
I an in Toronto. Is there any interest these
days in fan fold paper. I suspect that the
cost of shipping is more than the paper is
worth, so local pickup only.
If there is no interest, I will dispose of the
paper in June.

I recently completed a PCB layout for a serial board for the TRS-80 PT210
printing terminal. The primary intended means of connecting to a host to
this is an accoustic coupling modem. If you want to use RS232 serial, you
need an optional board. These boards have since become very hard to find,
so I used the info I found in the service manual to make my own. See
http://batchpcb.com/index.php/Products/59707 to get your own made.

A: Because it fouls the order in which people normally read text.
Q: Why is top-posting such a bad thing?
A: Top-posting.
Q: What is the most annoying thing in e-mail?
For general use on old personal computer systems, S100, Kaypro, etc....
Would a 5A variac be sufficient?
And is there any write ups anywhere on how to use the variac when powering
up a system that hasn?t been powered up in > 10 years?
I have had a very bad experience with sammyslave1, I bought two items an
extended mass storage rom for the HP9845 and a HP-IB interface for my HP
9830A. I always pay instantly with paypal, when I contacted the seller about
my items after a week or three I didn't get an answer, I waited another week
and another email no answer.
After I opened a dispute he answered and promised to ship the items and some
extra's for the inconvenience.
And yes his wife made a shipping label for USPS, but they never took the
package to the post office, eventually I upgraded to a claim and got my
money back, but what a waste of time this guy is.
It took me 8 weeks to get nothing, so my advice don't buy from sammyslave1
(aka Larry L.)

I have a Tandon TM-100-4 floppy drive that needs some work on the drive
door. Free for shipping from California.

I have 1 LaserJet IIp and 3 LaserJet IIIp printers. None of them are really
usable because the toner cartridges are either out of toner or the images
have streaks and blotches. I think all of them are functional electrically
and the paper feeding is still OK. It has been 3 years since I last tried
one.
I could always use an extra printer, so I have to decide if I should get
them working or just dump them and get something new when I really need it.
Is there a source for GOOD toner cartridges? Google finds a bunch of
cartridges, but how many are junk refills? I am willing to pay for good
cartridges, but I can't tell good from bad. Are feeding parts available if
they start to pull multiple sheets, etc? Are there reputable sources?
I know these have a good reputation generally, and I used one for a long
time in the '90s.

Apparently we're fortunate up here in Canada; although there are thousands
of cases in the bordering US states, according to many doctors the ticks
don't cross the border:
"...most Canadian doctors are woefully uneducated about Lyme Disease,
erroneously believing that it does not occur in Canada."
This is *not* a joke!

Does anyone have hex-height Unibus extender cards they would be willing
to part with, or loan?
We have created a printer interface card (based one the last rev of the
M8571 plus all relevant ECOs) for an LP20 in the front end of our Tops-10
system (a DECSYSTEM-2065). It turns out that the other cards in the LP20
are not entirely defect free, so we need to hook up a logic analyzer to
see where things are going wrong. We have no Unibus extenders, so we can't
do things like cool suspect delay pots.
We'd really prefer not to have to try building these. :-)
