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...) -Lawrence LeMay

11/83 backplane info needed

by CLASSICCMP＠trailing-edge.com

>I got an 11/83 in a rack mountable box (5 1/4"), and I would like >to know how many of the slots are type A/B and type C/D, as I have >a spare 11/83 cpu and a spare 1Mb mem. board, and they are >of the types AB & C/D. > >The backplane is identified as H9278-A and has 8 slots. 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. -- Tim Shoppa Email: shoppa(a)trailing-edge.com Trailing Edge Technology WWW: http://www.trailing-edge.com/ 7328 Bradley Blvd Voice: 301-767-5917 Bethesda, MD, USA 20817 Fax: 301-767-5927

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.

"Investment Grade" Classic Computers

by jeff.kaneko＠juno.com

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.

the latest virus

by allisonp＠world.std.com

>Don't laugh... I still appreciate my AMD 5x86-133 running msdos 6.22 and >WfWg 3.11..... Defiinitely and IE-free zone!!!! :-}) > >Stan 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. Allison

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* T --- This message brought to you by: trp0(a)falcon.cc.ukans.edu ..and the voices in his head.

HP calculator thermal printheads (HP82143, etc)

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. -- Pete Peter Turnbull Dept. of Computer Science University of York
