The drive might be salvageable, but I'm afraid the diskettes are toast. Does anyone out there have any 5-1/4 inch 10 sector (hard sectored) floppies? And a copy of the NorthStar DOS and BASIC that they'd like to sell/trade/etc? Hi Pat I think that the floppies will make it if you remove them >from the envelopes and rinse them off. I don't think there are any problems with being in water, otherwise. Most everything else should be cleaned up except switches and bearings. Mostly just washing the stuff with clean water and drying well. > >As for the HP64000s, the consoles are ok, but the disk drive drowned. From a quick search, I'm not real optimistic about finding another HPIB disk drive and I'm not too excited about plunging into this one to try and fix him (he was running when the waters came and he smells very bad). This is not good. Anything that was powered up when inundated is most likely in poor shape. Dwight Has anyone ever taught a PC (for example) with a GPIB card to think it's a CS80 Drive?? Does anyone have a spare disk gathering dust? Failing that, does anyone (besides me) still use these things? The consoles are probably too heavy to ship, but I have lots of cards, software, manuals etc in working order if anyone needs them. > >As to the other stuff, some is good, some isn't but if anyone needs any parts, I might be able to help out. > >Pat Fitzpatrick >

Goodnight, OS/2...

by Richard.Cini＠wachovia.com

OK, the inevitable Slashdot-type question...when will IBM open license OS/2 (if at all)? There have been calls for this for years before IBM finally nailed the coffin shut. -----Original Message----- From: cctalk-bounces at classiccmp.org [mailto:cctalk-bounces at classiccmp.org] On Behalf Of 'Computer Collector Newsletter' Sent: Friday, July 15, 2005 11:42 AM To: 'General Discussion: On-Topic and Off-Topic Posts' Subject: Goodnight, OS/2... http://www-306.ibm.com/fcgi-bin/common/ssi/ssialias?infotype=an&subtype=ca&a ppname=Demonstration&htmlfid=897/ENUS905-163 Or for minimalists: http://tinyurl.com/acbp2 ----------------------------------------- Evan Koblentz's personal homepage: http://www.snarc.net Also see: http://groups.yahoo.com/group/midatlanticretro/ Where did PDAs come from? http://www.snarc.net/pda/pda-treatise.htm *** Tell your friends about the (free!)

IBM Token Ring

I spent a year working for Proteon. I got a good lesson in all things Token Ring too. I still love it, but I'm not running any at this time. I'm not sure, but I might be the first person to have witnesses TCP/IP routed on TR hardware (at least commercially). My understanding is that Proteon offered that ability before anyone else, and I prototyped the boards and tested them. ---- There are only 10 types of people in the world, those who understand binary and those who don't.

There is both write protect and online functions. The alternate is just hard jumper it for enable on both. Allison

Yes, it needs power and ground (for the terminators and buffers) but has no other connections to the backplane. > - do I need the front panel 'thing' (the led board) or can I leave it > disconnected? You need it. I can't remember if it's the READY line or the WR.PROT that usually ends up in the wrong state otherwise, but one of them needs to be there (the READY line has to be grounded, IIRC). You can kludge it pretty easily. The layout and schematic for the M9058 distribution board are on my web site, along with the schematic for the LEDS-and-switches circuit. http://www.dunnington.u-net.com/public/RQDX/ -- Pete Peter Turnbull Network Manager University of York

Whitechapel CG-200

by julesrichardsonuk＠yahoo.co.uk

I've been offered one of these - anyone know anything about them? Google seems reluctant to divulge any info... We've got three Whitechapel MG-1 machines so I pounced on this one as a different example of the Whitechapel line - but I've been unable to find any info on it so far. As the MG-200 is appears to be a faster version of the MG-1, I'm assuming that the CG-200 is a variant on the MG-200 (likely with better video ability). The current owner was also told that it uses a Z8000 CPU, but I'm reasonably confident that it'll turn out to be a Natsemi 32016 like the other Whitechapel machines... We've got a few manuals for the MG-1, so hopefully it's similar enough that the docs will be relevant! cheers Jules

Free: CBM PETs, disk unit, Sinclair QL (Abingdon UK)

by julesrichardsonuk＠yahoo.co.uk

Got this one the other day - we don't need any more PET or QL stuff, and he's given me permission to post here. Contact him directly if interested - he's got a couple of weeks before he moves apparently. cheers Jules -------- Forwarded Message -------- From: Chris Jones <member at chilemonster.freeserve.co.uk> Reply-To: member at chilemonster.freeserve.co.uk To: donations at retrobeep.org Subject: Donation offer Date: Tue, 5 Jul 2005 08:43:53 +0200 (CEST) Hi Jules, I have two commodore CBM computers from the 80s which still work (an 8032 and 4032 upgraded from and labelled 3008). There is also a 5.25" disk drive (working) plus manuals/books/software etc. Would you be interested in adding them to your collection, or know someone that would? I am moving house and will readily donate them - I dont really want them to end up in land fill! There is also a sinclair QL and memory expansion/manuals etc. Thanks Chris Jones Abingdon

Repairing an HP 9810 (was Museums, etc)

by vp＠cs.drexel.edu

To help better understand Tony's (Duell) discussion of the 9810 repair, have a look at http://www.rheinfeld.de/andreas/9810.htm where Andreas also describes his repair of an 9810 using Tony's schmatics (available on the HPCC cdrom). **vp

Response from buyer of "Apple-1" on eBay

by vcf＠siconic.com

I finally got a response from the buyer of that "Apple-1" on eBay a few weeks back. In a nut shell, he said he suspected it was probably not an Apple-1 but he thought he'd take a chance anyway, and when he received it his "intuition" was confirmed. He thinks he got a good deal anyway because he says it was some sort of homebrew electronic "music box". -- 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 ]
