This is marginally off topic, but I picked up a DecTalk Express recently and I'm trying to get it working. Currently, I get nothing out of it whatsoever. I discovered that one of the surface-mounted fuses had blown so I've replaced that and I'm still getting nothing, though I am now at least getting a low voltage (about .5V) at components on the board when it's powered on. This unit has a rechargable ni-cad battery in it (that I'm pretty sure no longer holds a charge) and I'm curious whether a functioning battery is required for normal operation. Thanks as always, Josh

FFS: Programmers docs for Sperry UTS 4000

by dgriffi＠cs.csubak.edu

I have the programmer's documentation for the Sperry UTS 4000, a machine that ran CP/M Plus (aka CP/M 3.0). The pages are in good condition. The binder is in good condition. The slipcase has a couple scrapes on it. Free for shipping from California. -- David Griffith dgriffi at cs.csubak.edu A: Because it fouls the order in which people normally read text.

a for-parts machine doesn't work

by dgriffi＠cs.csubak.edu

Why would someone buy a vintage computer advertised as "for parts" and then complain to the buyer that it doesn't work? -- David Griffith dgriffi at cs.csubak.edu A: Because it fouls the order in which people normally read text.

Ohio Scientific Challenger 4P software

by lord_philip＠mac.com

Hi, Did you ever figure out you dilemma regarding your lack of Ohio Scientific floppy media? I'm basically in the same place having a disk system, but no floppies. I've even tried 'building' a floppy using disk images found on the net, but the process seems almost impossible and I ultimately failed. I've been requesting in various places and forums for anyone who can make me some copies of their working media, but no one has replied. this is certainly a sad state of affairs, and I worry that if too much more time passes then we may loose all working media.to ravages of time and may loose the ability to make new OSI floppies. I have also been helping develop a paddle board that will basically allow OSI users to replace their old and dying original drives with something more modern like a 3.5" disk drive. We have the first prototypes of the board in but I have thus far failed to get it working and need to do some further troubleshooting. In the future I really would like to build a database of software and disk images and find some way for diskless OSI users to bootstrap and create working floppies. Anyway, excuse the rant Cheers Phil

You know it is possible for something to work, but not to its full capability, right? The computer that I am typing this message on has a non-functioning DVD drive and occasionally the keyboard and touchpad just stop working. I would not describe it as 'worked fine the last time I used it'. Yet it works well enough that I can use it for lots of tasks. To the original poster, I agree that you probably didn't emphasize the 'for parts' aspect enough. I buy and sell a bunch of stuff online and one thing that I learned is that buyers often do not read things closely. alan

Philips P800 family minis

by camiel＠camicom.com

> I won an eBay auction for three Philips P800 family minis with three cartridge disc drives, disc cartridges, lots of spare parts, and manuals including schematics. All for the incredible sum of 10 euros 75. I saw the auction when it had 11 minutes left to go > while I was on vacation (I'm a bit of an eBay junkie, although deals like this are becoming rare). I'm collecting the systems this Sunday afternoon. If anyone wishes to try and identify them from the pictures in the auction: Ebay # 230793403766 Camiel

House move continues, more stuff available

by witchy＠binarydinosaurs.co.uk

I hate moving house as much as I hate giving away DEC stuff :( The PDP 11/04 is still here with its RX01 pair, amazed that hasn't gone in a hurry even if it IS a non-worker There's a couple of big monitors too, both mono and I'm fairly sure one each >from a VAXstation and VXT1200. I have VXTs too, base units. I have to be honest with myself that I'm not going to do anything with them. The usual haul of DEC books that everyone seems to have - microprocessor guides, terminals and printers, communications etc. At least 1 DECmate III w/keyboard, no screen though Battered looking Rainbow 100 LA210, maybe LA100 2 boxes of TRS80 software and manuals Apple II software and books. Not after any cash for this but you must collect from Cambs UK. -- Adrian/Witchy Binary Dinosaurs creator/curator Www.binarydinosaurs.co.uk - the UK's biggest private home computer collection?

Commodore Datasette Belt

by wheagy＠gmail.com

Yes, I can likely measure the length. Not sure of the width, or how that would be measured? As mentioned in an earlier post, it is a square belt, as opposed to flat or round.

vt100.net/manx now officially redirects to manx.classiccmp.org

by legalize＠xmission.com

Thanks to Paul Williams for putting the redirect in place. The new manx has now officially assumed all responsibilities of the old manx :-). I've been doing some work on it lately and I've fixed a couple cosmetic bugs and am restoring the editing/updating scripts so that I can work on getting the backlog of bitsavers items into the database. Priority will be given to items linked to bitsavers through the terminals wiki and then remaining bitsavers items. -- "The Direct3D Graphics Pipeline" free book <http://tinyurl.com/d3d-pipeline> The Computer Graphics Museum <http://computergraphicsmuseum.org> The Terminals Wiki <http://terminals.classiccmp.org> Legalize Adulthood!
