Yeah, and running conserver: http://www.conserver.com/ or something like it. Depending on how many serial ports you have, you can have a real multi-user setup with this.

Whenever time permits he has been looking at alternates to the current hardware. However, this system which has a rack of Fuji Eagles and a number of tape decks, has been running without much repair maintenance for the last several decades. We recently had to work on one of the Fujis and now are in the process of shot-gunning all the caps. We were totally amazed when one of the drives became flakey and found that nearly all the caps were bad - luckily Earl W. Muntz didn't work for Fuji... However, the current problem is not transporting the applications, but contacting the current system. Remember that RSTS is multiuser and he has no intention of also transporting his drones that also access the computer to the cool mountains with him :) There are also a number of customers that dial in to get access to data. Has anyone used any of the serial port ethernet servers (aka port directors) and how well did they work? -> CRC

OT: Re: internships

Cameron, you know I like you, but the way interns are abused is pure simple insanity. Heck, pick almost any "operator error" disaster you care to name - Chernobyl, Exxon Valdez, whatever - and odds are >> 80% that you will find someone either operating outside normal work hours or who had been recently doing so. On the last full mission I participated in, we made 4 critical errors during integration and test, any one of which could have damaged the spacecraft or terminated the mission - and *every one* of which was made outside normal working hours. Your own post that started this thread contained the phrase "Hope my overnight admission orders didn't kill anyone." Would you say that about any other part of your work? Would you want your loved ones admitted or treated by someone under those conditions? I admit there are conditions where doctors have to work long hours; I watched M*A*S*H just like everyone else. But *training* doctors to do that at the expense of patients' safety during normal times is dangerously bad policy, particularly considering the tiny percentage of doctors who will ever consent to work that way anytime during their professional lives. It's also educationally counterproductive, as anyone who has ever crammed overnight knows. Why and how the medical community, who has the best knowledge available of what physiological effects result from long-term sleep deprivation, ever allowed this practice, to say nothing of institutionalizing it, is beyond mystery and into mysterious evil as far as I'm concerned. I don't guess hospitals should be shut down but I think it would be a really good idea to take a few administrators and schedulers each month, ceremonially break legs or induce other disorders, and then admit them on the 36th hour of a new intern's first overnight shift. -- - Mark 210-379-4635 ----------------------------------------------------------------------- Large Asteroids headed toward planets inhabited by beings that don't have technology adequate to stop them: Think of it as Evolution in Fast-Forward.

I use a hardware TELNET <> LAT gateway, so I don't have to deal with power hungry multiplexors, serial cables, and baud rate limitations. Of course, since he's probably running V5A, he couldn't get that fancy. However, a plain ol' terminal server would be much easier to implement. Set the router to direct TELNET traffic to the terminal server, and voila ! T

F&*#ing chicklet keyboards (was Re: Retro Atari 400 looking Keyboard)

Some paid over $100 for an external "full-sized" keyboard. I bought a blue-bezel chiclet PET with the internal cable from Skyles Electric Works for the external keyboard (probably long since separated). <snip> Now (largely because issues of practicality are irrelevant), the price of a 1977/1978 chiclet-keyboard PET is several times that of a 1978 Graphic or Business-keyboard PET. -ethan ----- Reply ----- There was an upgrade kit available from Commodore, consisting of a replacement upper case half with the new Graphic keyboard, a new black decal and matching black monitor bezel, and an optional new external cassette deck to replace the internal missing-the-corner unit. I upgraded mine and also replaced the white screen with a green tube; glad now I kept the original parts for the day I sell it... m

Reproducing Printed Circuit Board Artwork

by mardy＠voysys.com

A few years ago I came to poses an original unassembled Altair 8800 kit. I have since decided to donate it to the Computer History Museum in Mountain View, California. But before I send it off, I would like to capture the printed circuit board artwork and make available to others wishing to reproduce bare boards. Can anyone recommend a service bureau, preferably somewhere on the east coast (US), that can do the work? -Mardy
