I have an old Amdek color composite monitor with a built-in speaker/amp.
I no longer have any use for it, and it's currently just taking up space.
I will take ANY offer + shipping for it.

Ok, it looks like the only way I have of getting source code from the 'net
on to the disks is to use EDIT and the "stuff text down the serial line"
hack in hyperterm. Assuming that I set hyperterm to send text slowly. What
are the minimum commands in EDIT to:
1) Open a new file.
2) Go into Insert Mode
3) Exit insert mode and save the file.

Ok, does anyone have an extra RQDX3 breakout board? This is the board that
connects to the controller and then it has connectors for an RX50 and MFM
hard drive(s).

Hey DEC DECMATE folks!
The fellow whose msg is copied below is looking for some advice on
re-belting a DECMATE II. As I have neither experience nor manual on the
machine, I feel some of you may help instead as you're the types who really
could.
Email directly to Bill. The machine is somewhere in Minnesota. Thanks muchly!
Regards, Chris

I picked up a Rockwell Aim65 today for zero cost and seems to be in great
shape. It looks like a large calculator and the housing is in very good
condition. Also picked up a few HP cables for no charge.
This one will NOT be converted into a bar:

Look at the size of that power connector!!!

I've dug out my copy of the manual for the Apollo Guidance Computer. The
files total about 165K; I don't think it's appropriate to mail them to the
list. But if you want a copy:
* Ask me and I'll send you one.
* Maybe DejaNews has the posts.
* Rich Drushel (who typed in the whole manual!) has a home page at:
http://junior.apk.net/~drushel
I didn't see the manual there but maybe I missed it. If anyone
e-mails Rich and finds he has a later version, please tell me.
I also have a separate 24K file (by Rich) with a giant picture of some of
the keypads and a bit of extra detail about the AGC. I'm not sure the
picture wasn't copied from the manual.
The message below was Rich's "foreword" to his posting of the manual. It's
fascinating, it's not too long, and Rich can explain the subject better than
I can. BTW, I had forgotten the fact that the computer changed over time,
each Apollo spacecraft had a few slightly-different "terminals", and the LEM
had its own version(s) of the computer. If you want to write a simulator,
your work is cut out for you.

The Apollo Guidance Computer (AGC)
revised 9601.14 by Richard F. Drushel (drushel(a)apk.net)
Periodically there are questions on alt.folklore.computers about what
kind of computers were used on board the spacecraft in the Apollo moon
program. Here are the definitive answers, reproduced directly from the
Apollo Operations Handbook for spacecraft SC 012--better known as Apollo 1.
After the fire on 27 January 1967 which killed astronauts Gus Grissom,
Ed White, and Roger Chaffee, NASA began a massive investigation into the
accident. Its 3-volume report, "Investigation into the Apollo 204 Accident",
published 10 April 1967, contains not only the accident report, but also
a wealth of supplementary data documenting the Apollo Command and Service
Modules. Included is the complete Apollo Operations Handbook, which gives
blueprints, block diagrams, schematics, theory of operations, how-to-fly-it
instructions, you name it--including the computer system.
I have broken Section 2, Subsection 2 (Guidance and Navigation
System (G&N)) into 4 parts for ease of posting. This is pages 2.2-1 to
2.2-48 of the Apollo Operations Handbook SM2A-03-SC012, or pages 443-488
of Volume II, Part 1 of the Apollo 204 Accident Report. Two of the four
figures in this section I reproduce as ASCII art; I've tried to keep it to
80 columns, but in a couple places it spills over, so don't read this with
your word wrap on. Of the other two figures, one is a beautiful line
drawing, and the other is a 4-page foldout block diagram. If I get around
to it, I'll put the text up on my WWW home page and make .GIFs of the
artwork.
This description of the Apollo Guidance Computer is only absolutely
correct for SC 012. A sister ship, SC 014, was completely dismantled during
the accident investigation, and some changes were made in the ship design.
Also, since SC 012 was a Block I spacecraft, it was never intended to dock
with a lunar module--it had no docking probe and tunnel--so any computer
programs dealing with translunar injection and lunar orbit rendezvous are
absent. As for hardware changes, I don't know if it was due to the fire, but
at some point before the manned lunar missions, the Bus A and B voltages were
increased from +28 VDC to +65 VDC. This had grave implications for Apollo 13:
the thermostatic switch for the heater in the oxygen tanks was never upgraded
>from +28 VDC, it shorted out during a manufacturing test using +65 VDC,
causing the heater to fail on for 8 hours, baking the inside at 1000 degrees
F and exposing the bare wires which shorted out so explosively in space.
Other changes from the state of SC 012 include the main hatch (changed after
Apollo 1) and the plumbing for the oxygen tanks (changed after Apollo 13).
The museum-quality sets in the 1995 Ron Howard film "Apollo 13" show
that the Block II computer keyboard was different from that of Block I. I
hope to add some ASCII art pictures of this sometime soon.
The Lunar Module computer was evidently similar to the AGC. At least
it shared the 1201 and 1202 error codes (which occurred during the lunar
descent on Apollo 11, nearly causing the landing to be aborted). I have not
found documentation similar to the Apollo Operations Handbook for the LM.
I've tried to catch all the typos, but some may remain. If you
find any, please let me know.
Enjoy! I did when I read it; that's why I was motivated to type it
all in :-)

RT utilities are deceptively simple and yet powerful.
I have a copy of the RT-11 System reference card here in front of me, so
if you need anything else, just ask...
>Now I'm dying to go home and try these out. Thanks Megan.
Any time...
