We have been trying to get working an LP20 printer interface on our
2065. We discovered just today that the issue we have had with bad
control signals was not due to bad boards, but rather was due to the
fact that the bottom 4 segments of the Unibus backplane into which
the control card plugs have no (0) wires wrapped around the pins.
We have the LP20 schematics, but the wiring diagram *for the backplane*
is not included. It also is not to be found on microfiche, although
there is a reference to it, with document numbers. We are specifically
looking for 70-11427, 54-11704, and 50-11703.
If anyone has any of these documents, please let us know ASAP. Otherwise,
a young EE is going to have to spend time with the complete set of LP20
schematics and a spreadsheet program to generate a wire list and re-wire
this thing by guess and by $DEITY, a process that will take several weeks
with no guarantee of correctness of result.
Thanks,
Rich

The VAXserver 8000 on your wanted list should be VAXstation 8000.
I have one, but it is missing the E&S graphics subsystem.
I didn't see any Calcomp System 25 Workstations in your collection.
The RICM has LOTS of them.

I just started using Google Adwords and I?m trying to figure out how they charge. I just finished the free first time allotment of $75, now I have to add more money.
Does anyone have any experience with this ?
Also I?m looking into the Yahoo/Bing adcenter.microsoft.com. They don?t seem to offer a free first time allotment. Does anyone know of any way to get a free startup allotment ?

Hi Liam,
I am not sure if it does make much sense to address these polite
"concerns" by the other chap... :)
If the person making this statement can make boards for EUR 20.- each
we'd be delighted to buy from him. For sure such price would be possible
when making 100,000+ boards. We do runs of 100, we have to pay for
electronics recycling (WEEE) registration, we pay tax, etc. I am sure
hobbyists only doing a few boards can get around such things, we can't.
We can't get even near this figure. For the record: the board is EUR
90.-; EUR 100.- is with cables we also have to buy to resell them.
The donations asked for are for the preservation project, maybe it would
have made sense to read the donations text file enclosed. And yes, even
MS Office has student and pro editions available, I don't see anything
wrong in charging companies that can afford to pay more. They keep it
free for private users, at least for our product.
Hello
I have two problems that I need help with, one is an IBM Card
Interpeter model 552 that has 3 broken legs. I think it's cast iron and
one welder told me he could weld the legs back on the unit. Does anyone
if these can be repaired or should we build a box with wheels to set it
in for museum display? The second problem is a set of Apple MAC 20th
Anv pens that have, the pen bodies have turned very soft and sticky and
help on stopping this so that these too can be part of a display?
Thanks,
John

The styling is definitely industrial, not military, which makes
me wonder if there was a commercial version of the D37.
(Univac had an industrial machine what was a repackaged version
of a military processor -- I don't recall the model.) More
likely, there was a repackaged version of the machine for use
in software development, with more appropriate peripherals for
testing code than a gyro platform and a nuke!

I'm trying to figure out how to contact the Oliver Klotz who used to sell
HP48 RAM cards on ebay a couple years ago. I'm trying to get my hands on
some and, if possible, schematics for higher-capacity cards.

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?
On another mailing list that I am on, someone was expressing the
desire to retrieve data off some old BBC Micro floppies to see if it
would be possible to get some of the software running on a Raspberry
Pi. They do not own any machine with a floppy interface.
I suggested KryoFlux as a possible solution.

Sorry, chaps, but I really do think you have a bit of a problem here
that you need to address!
