Hi
Is there anyone that is in the silicon valley area
that can program N82S181's? Also, does anyone have
a source for or N82S181C parts?
This is for an Olivetti M20 that I'm working on.

While I agree with the other answer that often there are several single phase supplies inside, connected to separate phases, note that there are some commercial solutions if you truly have one big power supply with a three phase primary on the transformer.
See http://www.phaseconverter.com/
and http://www.phase-a-matic.com/
for example.
These devices have a long life time and can be found on industrial surplus markets (which of course are on the web too)
I just received one of William's ASR33s and it appears to be in good
working order. I am not at all familiar with these machines so I have a
few questions about their operation and interfacing.
First off, when I power on this unit the "main" motor doesn't run. It
turns when moved manually, but it won't move by itself. Depending on
the motor position at power-up (I think) I sometimes hear what sounds
like a warning buzzer. Is there something I'm doing wrong? How would I
run this machine in "local" mode?
Once I figure out that this machine is working (I assume the problems
are mine and not the machines) I'd like to hook it up to my Altair
(which is now running great thanks to Dwight!). How would I go about
doing this? I'm guessing I'll need some sort of box to interface
between the TTY and RS232, but I haven't yet found any information on
that. Can anyone point me to an article, website or some other source
of information on this?
If I manage to get that all done, is there anyone on this list who has
software on paper tape that I could get copies of? I'd be most
interested in a BASIC variant and any BASIC programs that could run on
it, but anything else would be great.
What am I missing? Is there anything else I should know?
Thanks!

Oh gee, and I just have the a-hole friends that use me for tech support
for the life of their computer, and then when they decide to upgrade it,
they throw out the old one without even ASKING if I wanted it!!!! (sorry,
I'm a bit bitter since a friend's younger brother just did this to me. He
had an iMac that he bought used, and had been having problems with, and
has been using me for the last two years for support to keep it running.
Well, he got sick of it this week, and bought a new one. I found out last
night when my friend was raving about how great his brother's new iMac G4
was... and when I asked what he did with the old one, I just about drove
over there to choke the living shit out of the kid when I was told that
it went in the garbage on Wednesday's curbside pickup)

Hi,
I'm currently trying to build a COSMAC Elf, but unfortunately I can't
find any RCA CDP1861 "Pixie" video controllers anywhere. Has anyone got some
spares they feel like parting with? I've nearly got everything I need to
build an Elf, sans the Pixie chip. Some CDP1822 COSMOS RAMs would also be
nice. Right now I don't care if the parts are NOS, pulls or NOS in need of
serious cleaning. I just want these parts so I can build a COSMAC Elf!
Thanks.

It was on http://simh.trailing-edge.com/, I can't seem to get to the site
right now. The image was recently switched because macro wasn't working
correctly on the previous one (sorted out by Hans, thanks). It now should be
a copy of my tape s2.tu56 PDP-15 Master Tape S2 Page Mode (V5A Jan 24 1981)
The site also had instruction on how to boot it.
The rest of the pdp-9/15 tapes I have read are in
ftp://ftp.pdp8.net/pdp9-15/
I don't have an actual 9/15 to run them on. Anybody have a spare? Not all
seemed to work with the emulator.
Nice to hear the machine is running again.

I have one here, but I also have 3-phase. :-/
Sorry, no schematics on a 7000 power supply available. No schematics
whatsoever actually.
I do have full schematics on the PDP-11/70 on the other hand. :-)

Found a IIc+ the other day at the thrift store, someone screwed up, it was
only
marked $7something. Had a mouse attached to it, and it wasn't until I
got it home that I noticed it was an optical mouse. Mfgr'd by Mouse Systems
(or rather, `in Singapore for Mouse Systems'), the model number is
403009-001, and printed underneath it is `MSC 403009-1' and `S/N:EK
030724'. It seems that the IIc+
will take the older DE9 style Mac mice, so this might be for one of those.
Does this little guy need a fancy pad? Also, any pointers to IIc+ specific
sites? I'm googling, but I'd appreciate any hints.

Hello,
Just wanted to introduce myself. I collect older computers, mainly mini's
and Unix workstations. I have stuff from most of the companies that made any
of the above types of computers. I enjoy getting machines that work, or are
close to working, and actually using them. I also enjoy working with older
versions of Operating Systems and software. My ultimate goal is to get a
network of machines together and available to the Internet for others with
the same interest to access and enjoy.
I've just recently moved to the Dallas/Fort Worth area of Texas so if there
are any other collectors/hobbyists in the area I would love to talk to you!
Please send me an email and we'll chat about the hobby and maybe we can do
some trades.
Thanks,
Mike N.

P.S. I believe this post should be on topic because I am over 10 years old.
One of the well-known two-edged factors in collecting like we do is
the fact that all your friends/neighbors/colleagues/family decide you're
a better option than Goodwill. "Don't throw out that rusty 3.5" floppy
drive! Doc _collects_ that stuff!"
So when one of said friends makes a beeline for me at the meeting this
morning, and says "I heve a TRUNK FULL of stuff for you!" I just smile
and say "Oh, cool!" She's really excited about giving me this stuff....
We go out to her car and, yep. Four desktop floppy storage boxes. An
obviously dead, stripped Deskjet 520. Random power cables and phone
cords. An AT keyboard, sans most of the caps.
And then, O. My. Gods.
Two complete and apparently perfect Texas Instruments "Silent 700"
data terminals. One is roughly the shape of, and a little bigger than,
a Zenith 286 portable with built-in acoustic coupler, and the other is
smaller, in a soft carrying case, with external coupler and I think
those are two spare battery packs.
All righty then! I never had an actual printing terminal before.
This looks like hours and hours of frust^H^H^H^H, um, fun.
Doc
