Truely Ancient 2400 Baud Modems, last call!

by aw288＠osfn.org

The big cleanup continues, and these damn grey boxes are in the way. The grey boxes in question are a bunch of rackmount Western Electric 102B (or is it 201B?) modems, ex Goddard Space Flight Center. Apparently these handled encrypted voice and data, and perhaps some AUTODIN traffic. These are mostly 1967 builds, maybe a few from 1966. Getting 2400 baud thru a phone line back then required a foot tall section of rack space (21 inch!) full of cards stuffed with transistors. I have tried to sell these things, but they apparently belong in the lead balloon department. Being Western Electric from the good ole' days, these are dripping with gold, so I really need to get $50 a piece. So this is the last call. If you are interested, let me know, else they get scrapped. William Donzelli aw288 at osfn.org

(ick) There are mounting brackets available to allow one to mount a 3-1/2" devide in a 5-1/4" wide bay for modern PCs. Seems that this trick should also work with your 5160. The brackets add 'width' to the smaller drive and provide mounting holes on the outer dimension where they would normally be expected for a real 5-1/4" device. You can buy these kits, but you might actually be able to pick some up free from a local recycler. J

sad ebay listing

by jwstephens＠msm.umr.edu

I saw a calculator listing just now that said "turned it on, it glowed a minute, now it only glows green on the screen" "I'm not going to try to fix it"... THANK YOU. I'm not listing numbers so I don't get sued, but it isn't hard to find. Jim

What is an "AT&T 345i Safari"?

by trixter＠oldskool.org

Random woman emailed me that she has this thing and I don't know what to tell her. She uses the wording "monitor" but I can't tell if it really is a monitor or a laptop. She wrote: "The Monitor looks like a laptop with a handle on it. Sort of like a 60's 70's first battery operated radio. Very, very heavy. It is flat and opens like a laptop and has a screen and keyboard. I can send a pic to you if you like. The telephone don't go with it I figured out. LOL someone must have just stuck it in the big case for some reason. The booklet says it is an AT&T Color Monitor CRT 345i and it has Safari written on the top of it."

by hollobon＠gmail.com

Does anyone know if Xenix / Unix were ever available on the NS 16032 second processor for the BBC micro? I remember reading that it was intended to be made available in the user's guide years ago. Pete

Like, say, for example, ads that advertised ruggedized computers by saying they could survive a drop from the empire state building... Were there any? ;-) That would be a good show...
