While it's open, I also recommend you check continuity of the wires in the
cable. I've had a mouse fail because there was a serious kink in one of the
wires in the cable. That cable gets a lot of flexing and the kink
eventually broke that wire. I got an intermittent fault so I could localize
it by bending the cable manually and fix it by slitting the cable open,
splicing the wire, and taping it back up. That's not a very elegant fix,
but it worked. A whole new cable with a new connector at the end would be
nicer.

would you take $2.4000 ?

Maybe I'm thinking of all the 9600/14.4 modems I have worked with. Most of
the 2400 I came across were internals.

Well said... I agree entirely. It makes me really sad and somewhat
angry to think that some of this stuff can now only be bought by
people with deep pockets -- people who probably don't have any
contact with the computer field other than possibly using a PC... people
who will probably just have the thing on display, never used, or
people who's only interest is waiting for the price to climb yet
again so they can make their money back.
They essentially closes the door on the hobbyists, without whom the
home PC might never have existed.
I remember working on helping to build, and then later program one of
these machines when I was in college (1974-1978)... I've always wanted to
get one for the sake of memories, but that'll never happen now...
No, I don't want to see you kicked off the list either, but I can't
say that I will look forward to your posts either, especially if they are
about latest acquisitions/sales...

Hello again, everyone.
I'm looking for a power supply for a WANG WLTC laptop. It doesn't
necessarily need to be a WANG power supply. Just as long as it's 18V DC,
and at least 2 Amps.
I'm also looking for manuals for the WANG WLTC:
- Installation instructions
- Fundamentals Guide
- DOS Command Processor Guide
- Troubleshooting Guide
- Printer Software Administration Guide
- BASIC Language Guide
Again, they don't need to be originals. They can be copies.
As always, ThAnX in advance,

That's a darn good question. That's actually the sort of thing that
got me into collecting computers -- I wanted to learn something
practical about hardware. (Did I? No, not really; now I collect
because I'm an addict.)
The fundamental problem with the answer is that most of us are
cheap/spoiled. Me too. We've got used to being able to pick up
hacker toys for cheap. What can you do in the way of a new machine
built from existing schematics for say $50?
(Cue Tim Shoppa to tell us how much it would cost to build an IMSAI
today.)
Well, OK, maybe you don't need all that casework, it just gets in the
way when you want to do serious hardware hacking anyway.
Here's where I end up following this line of thought: hackable
singleboard kits. Personally I'm partial to something like a cross
between a microprocessor trainer or eval kit and the Morrow Micro
Decision (a Z80 with 64KB DRAM, floppy disk controller w/34-pin
connector, couple of serial ports), maybe y'all have other ideas.

Here you are on this mailing list, you make a statement like that, and
you don't past the statement of ignorance to asking for help? What
kind of idjit are you? Could it be that you're afraid you might start
learning things and thus end up like us? BWAHAHAHA!
Here's the kind of idjit that I am: been there, done that (well, it
was FOCAL, not Star Trek), and I can't remember what you have to type
at the SOL monitor prompt to load and run the program off tape. LO?
Do you have to give it load addresses, and tell it where to start
execution (EX?) after loading? I've got the documentation (for FOCAL)
but it'd be an afternoon of work to get to it right now. Bah.

Hi:
If you don't know the password to the system account under VMS, this isn't
much of a problem. Contact me on email for the bypass procedure.

NetBSD would be good for this machine. I run it on my Microvax II.

What is a Burroughs TD-700 display? Picked up two of them in pretty bad
shape, unknown if working or not(and don't know how to test), for free.
What are they, what do they do, how do they do it, etc... Lucky me, I got a
big book with the schematics! Kinda useless if you don't know what they
hook up to, though.
