I have a monitor for a Stardent workstation. It's a re-badge Sony, model number 130-0001-01. Free for pickup, or 1.2 * cost of shipping to recoup time and trouble if you want it shipped. Please respond soon if you are interested as it will be going off for scrap in a week if there are no takers. -- Sellam Ismail Vintage Computer Festival ------------------------------------------------------------------------------ International Man of Intrigue and Danger http://www.vintage.org [ Old computing resources for business || Buy/Sell/Trade Vintage Computers ] [ and academia at www.VintageTech.com || at http://marketplace.vintage.org ]

I've never imaged them as It's easier to replace the code outright. Curious why are you looking for them? Allison

Compaq SLT/286

by aw288＠osfn.org

Like the Sanyo just yesterday, I have a Compaq SLT/286 portable computer taking up space. Very nice condition, with power unit, dock, and bag. Any interest CHEAP? I am located in New York, zip 10512. Unlike the Sanyo, if there is no interest, I suppose I will just chop this up. I am desperately trying to clear out a bedroom to work on it - the bedroom that ends up being the junk overflow containment chamber. It would actually be nice to sleep in it sometime.

FDOS for Fluke 1720A

by geoffb＠vigilan.com

Does anyone have the O/S, Applications, and Diagnostice disks for this ancient IEEE 488 bus controller (Fluke 1720A)? It used a TI 9900 processor if I remember correctly. The operating system was called FDOS- a custom effort too I think, distributed on three 5 1/4" floppies. This is no longer available from anywhere or anyone, including Fluke. Thanks for any help and/or leads. Geoff

Kaypro System disks?

by brain＠jbrain.com

I have been fortunate to acquire a Kaypro system that appears to be in great condition and looks to work. It looks exactly like this: http://www.computermuseum.li/Testpage/Kaypro-I-Micro.htm Thus, it says Kaypro 1 on the artwork Still, the sticker on the rear says Kaypro 2, so I'm confused. In any event, I have no system disks for it (There is a slight possibility they are part of the stash with which the Kaypro was bundled, but it's 100 sq ft of stuff). Thus, I'm wondering if there is a kind soul who might be able to ship me a set of disks. (I'll pay shipping, of course). I also am the proud owner of 2 Obsorne machines (one works, the other seems to have drive issues. They are the redesigned units, but (as I suspected) the systems disks won't work on the Kaypro.

A Complete History Of Mainframe Computing

by lproven＠gmail.com

Tom's Hardware - a popular site for PC hardware tweakers and overclockers - has done an ambitious article on the development of the mainframe: http://www.tomshardware.com/picturestory/508-mainframe-computer-history.html It's a little American-centric but it's not at all bad. -- Liam Proven ?

PCjr Telnet Server Test

by mbbrutman-cctalk＠brutman.com

It's running! Telnet to 97.86.233.68 to take a look and help me test it. You can use the standard Windows telnet program, Putty, Linux, or whatever you have handy. Around 10 users can be on at the same time. When you sign on (no password required) there will be a little menu to help you waste some time. Some things you can do are see who else is on the server, view the machine type, ROM BIOS date and DOS version, check the TCP/IP statistics to see how much traffic it is handling, etc. There are some upgrades since the last time I ran this test (in Dec 2007): - The TCP/IP stack is much better - I'm doing 'telnet' negotiation to figure out the terminal type, turn echoing on, etc - Crude line editing has been added Right now it is running on my PCjr using a Xircom PE3 10BT. I plan to leave it up as long as it runs, or three days, whichever comes first. It is a PCjr so if there is a momentary delay, don't panic - it's probably just doing disk I/O. Backspace is a little dodgy .. it really wants ASCII 8 and a lot of terminals and emulators do ASCII 127 instead. Try variations with the shift and control keys if it doesn't work. Thanks, Mike

Wait! There's more including MS-DOS 1.25!!!! was Sanyo MBC-550 (Yuck!) software available

by rigdonj＠intellistar.net

I'm still digging. I found more 550 stuff. I think this is everything that came with the 550. Here's a chance for you 550 owner's to get the whole set at one shot! Original DS-DOS box and invoice. Original Sanyo Easywriter ver 1.3 disk Original Sanyo disk box with 550 dos ver 2.11 and BASIC 1.25, two original Sanyo disk for InfoStar (set B disk 2 and 3 of 4; disks 1 and 4 are below), original Sanyo disk for DOS 1.25 and BASIC ver 1.1 Original Sanyo disk box with all three original disk of set A, WordStar and CalcStar and a backup copy of DS-DOS. Two card board dummy disks used to protect the floppy drives duing shipment. Joe > >A few weeks ago we were talking about the Sanyo 550 series and someone mentioned one of the alternates operating systems that supported 80 track drives in the 550. I said that was DS-DOS by Michtron. > > Today I found an old Sanyo disk package with four disks for the 550. One of them is DS DOS 2.11, one is InfoStar, one is MailMerge/SpellStar and the other is a disk of misc utilities. The first three are original disks. In additon, the InfoStar, MailMerge/SpellStar are Sanyo labeled disks that came with the 550. If anyone wants them, trade me something I can use and they're all your's. > > Joe

I spec'd Tygon (brnad name) as that was available to me. Most any generic Vinyl tubing works so long as it fits tight and has enough wall thickness. After about 10 years it tends to get hard, the fix is obvious. Allison

Texas Instruments 960B

by aek＠bitsavers.org

> does anybody have bits for the TI 960B (not 960A) minicomputer, e.g. > software, schematics etc. ? I have some additional material on the 960 that isn't up yet on bitsavers. The 960 and 980 share some peripheral interfaces. Did you end up with the 990 system as well?
