I found a couple of cables with the cable checker and have not been able to find out what these things are. Both ends are terminated with RJ-45 connectors, and the cable checker has pins 1 & 8 (blue/black) and 2 & 7 (yellow/orange) shorted together. They have a tag labled "IBM P/N 58X9806". One of them has a date of March 1990; anyone know what these things are used for? Thanks!

The description appears to be copied from the Lisa 1 currently up on Ebay with a bid of $10K - http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&category=80075&item=514999 8223&rd=1 - suggesting that it's probably fraudulent.

Problems with my PDP 11/24 (was:Question about memory boards used on VAX 11/7xx)

Thanks for this information, Patrick. I guess, I'll have to wait for such a VAX, I haven't one yet ;-) Currently, I'm setting up my 11/24. It comes with an RL02. Yesterday, I worked on it a bit, checking grant and bus continuity, everything's fine now. I found out the bootstrap adress for the RL02 (BOOT Proms are located on the Unibus Map Module (KT24)) and gave it a try, with the RL02 disconnected. No problems with typing in digits with the VT420 terminal. This morning, the 11/24 apparently don't accepts commands from the terminal, why ? On the CPU-Board, the CLK-LED is always illuminated, even when I press the Boot-button. Then, the RUN - und the PROC-LED turns on for a moment, that's all. Yesterday, when I typed in the bootstrap adress of the diagnostics-PROM, the 1 - LED turned on. The 0 - LED always remained off. Today, no typing in is possible. When I press the boot-button, I obtain something like @000002 I need to know the meanings of the LEDs on the CPU-Board. Can anyone give me some help ? In the Maintenance-Card, the functions of the LEDs are described but it doesn't appear to be on the net somewhere... Thanks alot in advance !

Help: Looking for IBM timing belt replacement.

by h.j.stegeman＠hccnet.nl

Hi all, Who can help me with a source for a timing belt for my IBM 5203 line printer ? The old belt has given up after 13 years... See: http://home.hccnet.nl/h.j.stegeman/IBMbelt.jpg. It is a US sized belt: Tooth pitch: 0.125" (1/8)" (this pitch size makes it hard to find) Witdh belt: 0.500" (1/2)" Outer length: 13 inch (98 tooths) Thickness belt: +/- 0.080" Finding this belt in Europe is hopeless, all metrical sizes. Thanks for any reaction / tips that will make printer work again ! Regards Henk Stegeman IBM System/3 owner.

Available: old Vectra / MS-DOS 3.1 / QuietJet / misc manuals

by ss＠allegro.com

Hi, I received the following from a friend in France. If anyone is interested in it, email me and I'll send you his email address. ------- Forwarded message follows ------- ... While browsing my dad's attic a few days back, I stumbled on old Vectra and MS-DOS manuals, ca. '86. There is the complete documentation set that was sent with 286-powered machines, complete with MS-DOS 3.1 documentation, plus a QuietJet user manual, and a few other items. If you are interested, I can e-mail you a complete list. The stuff is yours for the price of shipping. If you are willing to pass this on to another possibly interested person, that's OK. Otherwise, it will all go to my dad's trash can. I've asked my dad to wait a few days [before trasking the stuff]. ... 91240 SAINT-MICHEL-SUR-ORGE FRANCE ------- End of forwarded message ------- thanks, Stan

Paging Roger Merchberger

by rcini＠optonline.net

I hate to use the CCList for this and I appologize in advance, but I can't reach Roger at any of his 30below.com addresses. Every message I send regarding the CCArchive List bounces. At this point I can only lurk on that list because I can't post to it from my subscribed email address. Thanks.

Not ten years old, but...

by gordon＠gjcp.net

... has anyone had experience of repairing Belinea DH-1764 monitors? It's a rather nice 17" monitor, but it has started losing width - the image is *almost* right with the width set to full but then the pincushion correction goes a bit funny. Cleaned up and resoldered obvious dry joints which stopped the flickering. Dried up electrolytic somewhere? The original symptoms were a width-wise flickering *very* intermittently, then one day I turned it on and the picture was a couple of inches too narrow. Gordon.
