For quite a few years, one bit of folklore that has popped up on a regular basis is that of old IBM dinosaurs running our air traffic control system. Well, I was just wasting some (work)time now looking at some recent threads on <bit.listserv.ibm-main>, and it is fairly clear that the 9020s are now all gone after probably too many years of service. The interesting thing is that the machines that replaced them, 3083s, are also now considered classics. William Donzelli william(a)ans.net

Strange PCjr found

by Marty＠itgonline.com

I have a PCJr with a box (dimensions are same depth and height as system unit but is about 2 1/2" wide) that is mounted on the right hand side of the system unit and contains a parallel port. Is this what you are describing? Marty

Demography?

Slightly on topic... tip for linux?

by DSEAGRAV＠toad.xkl.com

Does anyone know if there is a tip for Linux? (The comm program?) It had an option to go to another port if the one needed was busy. Minicom can't do that. I would like that ability, 'cause when I connect the 44 here, I'd like to have people telnet to a port and get passed straight into the DH plug, via pip, without having to have an account on the PC -------

value of Sol 20 and Imsai 8080

by altair8800＠hotmail.com

I am in the market for a Sol 20 and and/or an Imsai 8080. I would like to know what the "going" price is so that I will know how much to pay for them if they become available to me. Any opinions would be welcome. Thanks, Bob ______________________________________________________ Get Your Private, Free Email at http://www.hotmail.com

VSchool: (Directed at kids, but adult's welcome too!) Just an idea...

by photze＠batelco.com.bh

Hello. Several days ago, under the demography thread I briefly mentioned the "VSchool" concept. So, for those interested, here's what I want to do. Background info: The VSchool idea came from two needs: my need to create a virtual community, and, more importantly, the need for children (ages pretty much 6th grade-12th grade) to be able to learn at their own rate. At the subjects that they're interested in, or feel weak in. So, I then think of a place where all this could take place, actively, and freely. Now, Bahrain is far to remote to even begin to demonstrate something. Also, it's got limited resources and views. The Internet. It's used by far more than the population of any city, and equal to that of many countries. How I plan to pull it off: This is the area that I don't have to spend 50 lines telling you what CGI is and does. So, I'll use CGI (anyone got info on this?) to put up forms, (I can't program it... sorry...), and then we can make a chat room of some sort, possibly a Javascript password form. (Ok, so I'll need lots of help) So far, the best deal that I've seen in web hosting is digitalchainsaw (at http://www.digitalchainsaw.net) Anyway, we'll have two functions: Students will "enroll" (for free), and then they'll choose their area of expertise. There, they will be considered a teacher. In other areas, they'll be considered students. Teachers will work together to develop a curriculum. Then, they'll work together to teach others. I want to have a copmputer history as well as a computer interest group. I'm asking for your help. You would be considered a partner, if you wanted. Thanks, Tim D. Hotze

I am fairly comfortable with sending these overseas for preservation. I expect to back the code up in several places; on the web, distributed to whomever of you indicates interest, and also on duplicate EPROMS, on my computer, tattooed in hex on my shoulder... that should just about do it. :) What sort of reliability does well made, but 23 year old, wire wrap circuitry have? Is wire-wrap susceptible to "slip"? Cheers A

I have Yes, but not very enthusiastically. I've never really got into electronic music, preferring to do my composing (and most of my playing) at the piano. But, (getting a little closer to the topic) I do have a rather fun device - a Bontempi organ with a number of built in rhythms implemented in 74-series discrete gate TTL. > BTW Any of you UK guys have collections of the old E&MM magazine?

Still, nice to hear from another one. (On the other hand, there is probably a strong correlation between bassoonists and eccentrics, and a stronger one between this list and eccentrics.) Philip.
