Ok, i finally found the guy at his office (we work for the same department
here at the university ;) and had a chat. Looks liek he might try to get
me the pdp8/e cpu (without any boards) and the boards if he can find the
box that they are in.
This leaves 2 RK05's and a Dectape unit.. is anyone willing to pay a
reasonable amount, AND pick this stuff up in minneapolis, AND do it
pretty quickly? I know Dectape units are worth about $1000, so this
is a worthwile thing to get if you have teh space for it (the curse
of working for the university, is that they dont pay me enough to
be able to afford the space for all thsi stuff)...
If you want this, speak up and i'll go see what i can arrange with
him. i want the cpu, and boards if they are found (my 8/e has no
interface boards, and front panel is damaged, and power cable is
cut, as you might recall...)

First clue: for just about anything Q-bus, you can find the answer
in the Micronotes. They're online at
http://metalab.unc.edu/pub/academic/computer-science/history/pdp-11/
just click on "Micronotes".
What you're looking for is specifically in Micronte #5, _Q22 Compatible
Options_. It tells you
Micro/PDP-11 H9278 4 X 3 Q22/CD and 4 X 5 Q22/Q22 Backplane
In other words, just the standard BA23 backplane, the first 3 slots
are AB/CD slots, the remaining 5 are AB/AB in a serpentine pattern.

Hi all,
With no small amount of regret, I am liquidating most of my collection in
order to focus my attention on a personal matter which is going to require
100% of my time and energy. Thank you all for the sense of community and
spirit of comradery here for the past few years. I'm hope to still hang
around here and there (VCF, I'll be there!) but will not be actively
collecting. Believe me, this decision was not made lightly.
My classic computing page will remain as it is, and the list archives will
remain there, as will the documentation that I've already scanned. As far
as current transactions, I will complete them as soon as possible (Sorry
Rich, others). Especially the couple of people that I still owe shipping
to, I'm trying to get my ass in gear here...
Ok, on to the good stuff. I will ship small items and books, anything more
than a few pounds will only be available to someone who wants to pick it
up in Glendora, CA or pay to have mailboxes etc pack and ship it.

Tonight I added the mini-assembler and memory block saves&loads to the 1802
simulator. The 95/98/nt console binary and source-code are at:

Up there.
Let me know if it doesn't do what you think it should.

Guys:
I'm faced with a dilemma, and I'm polling for opinions.
Some time ago, I swore I would never again publicly
broadcast (via this ML) ads for computers that could be
considered "Investment Grade".
Those of you who have been around long enough know what
I'm talking about; a machines that tend to fetch
an obscene amount of money, despite the general opinion
that they really aren't worth that much.
The general objection is that such sales unreasonably
inflates the co$t of our hobby, so we can't afford it
anymore.
The dilemma is this: A friend of mine has such an
"Investment Grade" machine; and he wants to sell it to
the highest bidder <cringe>. Now I'm faced with two
bad choices: Put it up on e-bay, or post it to this
forum. I dislike e-bay for what it did to our hobby.
I'm not comfortable posting it here, because I have a
deep respect for the collectors/hobbyists here (of all
stripes), and their opinions on the effects
commercialization has had on our hobby (not to mention
my own conscience).
My friend *specifically* requested I post the ad here,
as he was quite pleased with the result, previously. I
will only do this if you guys feel this is the appropriate
thing for me to do: I post the description, interested
parties submit bids, *OFF LIST*.
What say you all?
Thanks.
Jeff

Thats a fast system.
When you consider that by just running IE4.01 instead of 5.0 you've reduced
you footprint and exposure it's something. Also if your apps don't need it
Pulling VBA300.dll helps as thats needed to execute VB scripts.
You could also pull IE and use Netscape, that works well.
Then again you could run dos6.22 and Newdeal software (www.newdeal.com)
and get all the stuff without the disk footprint.

Hello group,
Here's something we all knew already, but we need to educate the brainwashed
masses about Microslop . . . Last sentence says it all.
*** FORWARDED MESSAGE ***
Original author: trp0
Written on: 05-May-00
*** Beginning of forwarded message ***
Last night, Ted explored the "I Love You" crisis with three "computer
virus experts". I'm a little fuzzy on who everyone was for sure, but I
know one was a computer crime prosecutor, another was Thrilling(sp?) from
Symantec(who totally reminds of this one stand-up comic guy...looks and
acts just like the stnad-up....maybe secret alter ego), and I don't
remember the other guy's functions at all. All three were going on and on
about how users needed to protect themselves with better and more
anti-virus software as well as putting up home firewalls!
It struck me as odd that they were trying to "educate" people about how to
be safe without ever mentioning the fact that nearly all of the nasty
email viruses are confined to Microsoft products. I would have liked to
have seen a discussion about why MS doesn't consider these things as big
hole in their OS. Seems to my like a large majority of even the standard
viruses live in the MS realm. Wouldn't it strike you as a little alarming
if the product you are turning out is the target of so many easily
constructed destructive programs because of the way your product is
designed and implemented?
Anyway. It was just strange that they were emphasizing that basically all
the world's email systems were brought down because of this thing without
even noting things such as alternatives that wouldn't have these
problems....instead trying to scare the public into consuming more
unecessary software to patch up a leaky operating system with third party
products instead of encouraging people to get a brain and exercise their
free-market will to force product improvement.
*shrug*

Depends on what stress it might be subject, I suppose.

Ah. Given the thickness of the paint, painting tracks would be difficult,
even with a good-quality fine brush. The only other suggestion I can think
of, is to paint a wide strip, covering all 8 tracks, and then use a scalpel
blade (and some patience) to gently scratch gaps between them.
