As I understand it the light pen detects the electron beam on the CRT
display as it passes the end of the pen and can decode from the timing where
the pen is located. Somewhere I have a light pen kit that was used to
emulate certain types of IBM terminals. Many hospitals used light pens to
move through the menus for patient registration and order entry.

Bill,
I tried that. I navigated to /usr/openwin/bin/ and typed openwin at the #
prompt. The OS returned the message "openwin: not found"
:-( Ideas?
Thanks,
Drew
p.s. - I'm logged in as root if that makes a difference. I'd also like to
set up a seperate user account... I'm going to try to look around for a way
to set up a user account.
>/usr/openwin/bin/openwin should work... if you didn't install CDE.

Well, I am back from my trip to London and picked up my 3 boxes.
There are *a lot* of vintage documentation on the transputer including
but not limited to:
full 3L compilers (Pascal, C, & Fortran) with TBug debugger
IMSD100 Occam compiler
IMSD705B Occam compiler
A nearly complete collection of Occam Users Group newsletters
A nearly complete inmos tech notes
whitepapers, product info on various transputer vendors
user guides for various inmos & transtech boards
and boxes and boxes of floppy disks contains various transputer
programs and support software. Unfortunately, I didnt have
enough space to take the floppy disks, so I had to leave it behind
in our London office. I got to pick it up later on when I get back
there.
As for boards, I am the proud owner of:
2 IMSB012 16-slot transputer tram boards
1 IMSB004-4 evaluation board
1 IMSB001 evaluation board
4 TTG1 graphics tram
1 TTM110 T805 + i860 Vector processor tram
and 1 M212 disk controller of some sort. Most of the
ICs are missing including the M212. Seems to be
some prototype or unfinished board.
I'll start sorting out these and start scanning a lot of the
documentation. The nice thing about these is it is not
in book format, so making it a lot easier to scan. Now,
I just need some time to actual do the scanning :-(
Cheers,
Ram
PS: Still looking for an IMSB000 - must be quite rare.....

The latest addition includes three DECstation 5000/2xx's, one each of
/200, /240, & /260. Also included was two expansion boxes with two
RZ58's, a TZK12 1/4 tape drive, & a RRD42 CDROM drive. Also got a
TK50Z-GA, and a couple 90TL DECservers.
One machine is loaded memory wise, 288 mb. Another has a couple
extra Turbochannel cards. The first is the TCE Option Module.
The second is an AV01B. It has 60 pin mini-D and two 4 pin RJ
connectors. Some digging revealed it is an "DECaudio card
and distribution box (LOFI)". Anybody know anything beyond that?
Also got a DEC PC. It is a Venturis, 486/66. It came with a mono
VGA monitor. Looking over the mainboard, I found where the pins
would go if it had a color option, and there is a place to surface
mount what I assume is the additional memory for the color option.
Also got two boxes of manuals, and a box of original DEC software
tapes. The tapes include two versions of Ultrix and the tape for
the 90TL.
The box of keyboards contained 9 DEC keyboards, mostly LK201.
If this keeps up, I going to have to buy one of those small
storage sheds just to store the extra keyboards that seem to
keep wandering in.
No doubt about it, I got a case of 'mental DECay', and I got it bad.

Nice to see such interest in the BBC - I keep forgetting it's
not very common outside of the UK. I've got a couple of spare
BBC Masters up for swaps if anyone's interested? I'm looking for
Xerox technical manuals (see list), software, even hardware if
the shipping's not too prohibitive :-) The machines I've got
don't have any documentation or software (although you can still
buy new Master manuals from 8BS and download whatever you need
>from all over the net) - they both have a sticky key or two and
could probably do with a makeover. I did a first pass at cleaning
them up when I got them but haven't spent as much time on them
as I could ("my" Beeb gets most of the attention!).
If you're not familiar with the Master, it was the follow-on from
the Model B and Model B+. Basically the same hardware as the B/B+
with 128K RAM (paged) and a 6510 in place of the 6502, housed in
a bigger case with "enhanced" keyboard (ie a keypad) and a couple
of cartridge sockets. All the I/O ports of the B/B+ were retained
(disk, RS423, 1MMz Bus, "Tube" etc), and they added a couple of
popular application ROMs (View and ViewSheet) as well as the ADFS
and DFS filing system ROMs as standard (you had to buy these yourself
on the earlier B/B+ machines). For us hackers they added a terminal
emulator, upgraded BASIC (BASIC IV) and upgraded assembler, very nice!
Anyhow, if you're interested in swapping, I'm looking for the
following Xerox manuals:
XDE 12.0 Users Guide (or later)
Mesa Language Manual (11.0 or later)
Mesa Programmers Manual
ViewPoint Programmers Manual
Pilot Programmers Manual
Basic Workstation Programmers Manual
Services Programmers Manuals
Either hardcopy or original VP softcopy is fine :-) If you've
got something I've missed off the list I might be interested,
drop me a line.
Cheers

The DEMSA was sold as (at least):
DECrouter 2000 - Phase IV DECnet router
X25 Router 2000 - Phase IV X.25 and DECnet router
WANrouter 500 - Phase V (OSI) DECnet router
X25gateway 500 - Phase V (OSI) X.25 gateway (no decnet routing)
(It's been a long time, so names and numbers
are only approximate ...!)
There were also variants with different numbers to
run on the single port hardware (DEMSB). So there
was (IIRC) an X25gateway 100 for the DEMSB.
It could also run SNA software but I had nothing
to do with that. The original SNA software would
have been for a Phase IV environent. There may
have been a later version for a Phase V environment
but I don't think there would have been a need for that.
The DESNB was a MicroVAX 3600 with some
sort of IBM channel connect. Basically
a DEMSA with a big pipe into the IBM
box. AFAIK the only software that ran on this
was the SNA software.

Greetings!
Several changes people have been asking about... here's the status....
1) The classiccmp mailing list archives at www.classiccmp.org are now
reworked and up to date. We are still using hypermail which takes the
mailing list traffic and automagically creates the website, organized by
year, month, thread, etc. etc. A background process is *STILL* running to
populate the rest of year 1999 (other years, including 2000, are already
done) but it should be done in an hour or two perhaps (theres a LOT of mail
to process in portions of that year). There is a month or two missing, but
those months are actually missing from the raw datafiles. I assume that the
list was not functioning during those times (before [and perhaps while] it
was being moved to my servers).
2) The hypermail task has been set up as a cron job to keep the mailing list
archives at www.classiccmp.org up to date without operator intervention.
Because the mailing list is hosted by a server sitting right next to the
classiccmp webserver, updates to the archive will be especially fast.
3) Previously, digest subscribers could get multiple digests per day if the
size of the digest was large (ie. it could be split into multiple emails if
the size went over a threshold). Due to popular request, that is no longer
the case. The digest will now send only one email per day to digest
subscribers no matter what the size.
4) Several people have asked - I don't have their email addresses here... so
once again - publicly, to subscribe or unsubscribe send an email to
majordomo(a)classiccmp.org. Any list traffic should go to
classiccmp(a)classiccmp.org. When subscribing you tell it which list you want
to subscribe to, either the normal list or the digest list.
Hope this gets everything in order.
Once again, I will gladly host any website, ftpsite, mailinglist, etc. that
has to do with classic computers at no charge - unlimited traffic, unlimited
storage, no fees of any kind. I am currently connected to 5 major backbones
via 100mb ethernet (and offer local dialup in over 152 US cities [shameless
plug]), so the transfer speeds should be acceptable. The only thing I ask is
that if the disk storage requirements are unusually large (say, greater than
10gb) that you buy your own hard drive and ship it to me. I'll mount it in
one of our servers and the drive will still belong to you and be dedicated
to your use only. If you decide to move, you get the drive back of course.
I'll do this for free, I feel it's something I can give back to the folks on
the list for all the endless advice I've gotten out of it. Ok, if a few
RK05's and 7900A disc drives show up anonymously, I won't complain either
<grin, just kidding>.
It would be nice if we could get a lot of subsites under the
www.classiccmp.org site, sort of like a portal. At the very least we need
some links to classiccmp sites there. Anyone care to throw together a main
page for this (I'm not an html person, and our webdevelopment staff is
working overtime already)? Then all the subsites that folks host on my
server could be at www.classiccmp.org/mydecstuff and
www.classiccmp.org/hprules for example. Of course, if you want your own
domain name that's fine too.
Regards!

Hi. I'm searching for some HPUX docs and software for the HP 9020.
I think HPUX 5.? is still running...

Yes. The control board in my Dad's garage door opener was killed by a close
lightning strike. My sister, who owns the house next door to him, lost the
motherboard on her PC -- and it wasn't on at the time, just plugged in.

Hi,
I got a good deal of a Commodore 1701 monitor on eBay, just that
it was not well packed and damaged during the USPS trip. Now I
have a lightly damaged enclosure with everything inside apparently
working except the horizontal scan. The picture is squeezed into
one single vertical line in the middle of the screen. So, what's
next?
Does anyone have a schematics of that monitor, so I could find
my way through without an oscilloscope? Any idea how I could
get an oscilloscope for repairing this? Any idea where I should
start?
I once repaired something on a TV set which was amazingly simple,
but I'm not sure I can redo that here without help.
Thanks,
-Gunther
