HP CP/M system - [WAS Re: Craziest ebay price EVER]

by Glen.Heiberg＠gijima.com

Warren wrote: ================== Oh, yeah, the GPIB reference reminds me... I've got an HP CP/M machine, too, that looks like their old brown monitors, with a standalone dual diskette drive that connects via HPIB. I forget the model number... Cripes, I've got old computers stashed all over the place. ================== Must be an HP 125; if it's a 3.5" disk drive, chances are it's an HP 9121D.

CD-ROM archiving

by sethm＠loomcom.com

Hey folks, Does anyone have any guidelines about making archival images of CD-ROM media? For years, I've been using dd on Solaris or Linux to dump the raw bytes of CD-ROMs, and cdrecord if I want to make a copy from the raw image, but I don't know if this is considered "good enough" to preserve all the associated filesystem and partition structures of the disc. It has been for me, so far, but I'd like to hear other opinions on the matter. How do you archive CD-ROM images? Does anyone use any special software or have any tips? -Seth

Intel MDS and Mohawk

by cclist＠sydex.com

I was going over some old 8" Intel diskettes and discovered some that have the legend "MDS is a registered trademark of Mohawk Data Science Corporation" Does anyone remember when Intel started adding the asterisked text to "MDS"? Cheers, Chuck

Western Union self-winding clock

by jedwards4＠cinci.rr.com

Saw your note re self winding clocks on the net and that your dad had one. I am also in possession of one and trying to find the value of it. Have you or your dad ever come across a book(s) or web site that provides some type of value to these clocks. I have tried using the web search engines without any success. Matter of fact that is how I found your request. Any assistance or help you could provide would be appreciated. Jerry Edwards

Western Union self-winding clock

by jedwards4＠cinci.rr.com

I am a former Western Union employee and while there I got my hands on one of the self winding advertising clocks WU offered with its time service. Saw your articles on the web and wondering if you could point me in the direction of a web site or book(s) that I might be able to find the value of this clock. As information, I have already tried using most of the web search engines such as Google, MSN, Yahoo etc., without much success. Matter of fact that is how I found your articles. Any help or assistance you could provide would be very much apprecated. Jerry Edwards

Wanted: OS / diag media for Altos 886

by rescue＠hawkmountain.net

I have an Altos 886 that apparently has corrupted boot blocks... and need to locate a copy of Xenix and probably of the SDX ? diagnostics in order to get it back up and running again. As I understand it, this system ran Xenix 3.2f, and it had to be the Xenix specifically for the Altos 886 (i.e. not 'generic' SCO Xenix). So, anyone out there have installation media that they care to part with or make copies of ? (copying may be difficult as these are Quad density 5.25" media as I understand it... 720K I believe (80 tracks double sided double density)). Thanks, -- Curt

Faraday cages ( was Re: staticy plastic tubs )

I had forgotten about Google (not surprising since I have been working 8.5 hour days for the past week and only getting 6 hours sleep each night). I don't like to rely too heavily on Wikipedia as (like alot of information online) you can't be sure what's right or wrong, unless someone knowledgeable in the subject can confirm it. So if I understand correctly, the outer casing of a harddrive acts as a Faraday cage? My (4GB) Toshiba ones I use in my Amiga 600 have circuitry on the underside, but I suspect that may stop it being a Faraday cage, unless it's stuck onto the outside of the unit.

vax 1000 matching monitor

by ying6926＠ureach.com

We had one monitor Phillips C1435-AS that goes with a DEC Vax 1000, but the monitor is dead now and it has DB9 female connector. Does any one know the specification of this so that I can find a match or does anyone know of video card on vax 1000 computer? I was told it is typically EGA signal out of vax1000 and I was told by some people it is actually analog signal with DB9 connector with special pin match. Any help would be appreciated. Henry

RL02 latch cable

by jwest＠classiccmp.org

Does anyone have some experience with the best way to "lubricate?" the cable in the top cover of an RL02 drive? I can't tell for sure if the cable is wire or plastic or plasticoated wire or fiber..... The issue is probably typical... when you release the hand operated slide the clasp on the top cover at the front doesn't slide back all the way to latch the top closed. I am sure that it is not the spring in the front latch. Moving that by hand, there is plenty of spring tension left. The problem is definitely that the cable between the front latch and the hand operated slide isn't "sliding" in the channel. What good way have people found to address this. If it's fiber I was thinking of sliding the cable through wax once or twice. Is there a better way? Graphite would seem a bad idea.... Jay

Kennedy 96xx series docs on line

by aek＠bitsavers.org

I was able to obtain copies of most of the 96xx series manuals last Friday, so they are now on line on bitsavers.org/pdf/kennedy including the docs for the SCSI interfaces. They were a challenge to find.. Still looking for the schematics for the HP 88780
