Hi Group:
I have an old 11/23 with an H7861 power supply. It's a Q bus box. The
cabinet kit is missing. There is a ten wire ribbon cable from the power
supply. I am looking for the pinout of this ribbon cable, so that I can
make my own panel. The leads likely carry DC OK, Halt, Restart, and so on.
Anybody have the info on this?
Thanks in advance,
Kevin

Chuck McManis said speaking of EBAY:
>It sounds like this is a "bad" thing. Is it? If so why?
----- START RANT -----------------
Yes, it a Baaad thing. I was very happy when my computers were "worthless"
(to everyone else), thank you very much for asking.
1) Computers are appearing everywhere. I don't have to look so hard
any more. As a result I don't yell "Yipee" as loud any more, especially
when I realize what it's going to cost me.
2) A good portion of the discussions on this list are about what some
machine is
worth. A hobby that allows a person to gain complex knowledge of
so many aspects of their machines and it history has been reducted
to the level of baseball trading cards and "beanies". I would
rather hear about how someone just got a machine running for the
first time in 15 years.
3) I see a "Low Tech" craze coming. People will be mounting S-100 boards
to hang on the wall. Just like the people that buy old magazines,
cut them up to frame the old advertisements. By piecing out a computer
they make alot of money, and someone has a piece of Americana to
decorate their den, but it's taking technology out of context.
This will come when the prices "crash". Imagine you need a S-100 disk
controller. You find one,it costs a fortune and you need to chip it
out of a block of Lucite, because someone made it into a paper weight.
4) I don't care for the way it makes people react. The following is from
the CP/M list last weekend:
>About a week or so I let loose that I had a few IMSAI chassis available.
>This resulted in a deluge of mailings. I was rather amazed at this - that
>anyone would want them at all.
>I offered them for free (postage) and still am doing so. A couple of
takers
>have been identified.
>What I cannot abide is a few that got real abusive. I was offering
something
>for nothing, yet a few insisted on demanding they get the equipment. I
>received some nasty insinuations and threats. This I will not
tolerate and
>each party has been told so personally.
>I wish to reiterate here that I am appalled at the behavior of these
few. It
>was fortunate that the majority had better manners. I nearly tossed the
>whole batch in the garbage.
>Excuse the venting - Sorry about the whole mess
>Rich Raspenti
5) "Beanies" are made to be collectible. They don't have a story to tell.
They don't have a functionality that is greater than the sum of their
parts. You don't play with them. You just display them.
And that is the biggest problem. When a treasured possession becames too
valuable to use for fear of damaging it, that defeats MY purpose for
collecting computers.

Again, this is well discussed in Q16 ("Can I use the newer floppy
drives on my old machine?") of the CP/M FAQ. See

And there are several
tools - most notably Teledisk - which can handle split-density
floppies.

There are parts of APEX that you need a hard-hat to enter :-).

Anyone have any pulled MA3172s they can help this gent with or know of a
source for them? All I have are dead 8514s and I'm not good with a
soldering iron--I don't think this fella would want to buy/ship the whole
monitor just for the chip and I would destroy it if I tried to pull it.

i'd use mess-dos 5 myself. help files, and a workable editor makes it worth it
but still small enough to run from floppy.
In a message dated 98-10-27 13:58:09 EST, you write:
<<
Weeeeeeeell, I landed a Data General One laptop. Normally I eschew MS-DOS
based machines, simply because I'm a racist pig etc., but this one has an
interesting notebook mode and a built-in terminal program at 1200bps. Except
that the screen is harder to read than James Joyce, it seems like a winner
and it works great.
Question. Anyone know what version of DOS this uses? Does someone have any
boot disks out there, or at least have the system files available for
download? The drives are 3.5" DD, right?
Thanks much, >>
