regarding Commodore SX-64 picture tubes and other stuff

by rampaginggreenhulk＠yahoo.com

I have them listen on eBay amongst many other items. The tubes for sure will likely be dumpsterized if they don't sell (and for some reason beyond my comprehension not one has in a couple of years). As for the rest of the stuff - who knows, perhaps the same fate. I'm determined, but not ultimately dead set on emptying out the last of my storage units. I'm keeping my most gorgeous loved items, not getting out of puters altogether. It just seems crazy to hold onto it all forever. I threw out a Rainbow monitor last night even! You were forewarned...

server migration

by jwest＠huey.classiccmp.org

Not sure, but I think I have a few hours squirreled away to try and work on the mailman/email migration. It will likely be a bumpy ride. I'll start looking in to it now. If I can get enough of the mailman system transferred in the time I have, then I'll start looking at the mail transfer if that goes well. I'll keep you all posted. Expect an outage or two. J

HP 9865A Cassette Memory service manual?

by derschjo＠gmail.com

Picked up a very dirty but nearly entirely functional HP 9810A recently, with 9865ACassette Memory drive. While I wait for parts to repair the 9810's mag card reader and printer to arrive, I've been working on cleaning up the9865A. It is almost working (and the few rubber parts in it seem to be good) -- however it will not move the tape forward. There are two solenoids that control the direction of the tape and one of them (for the forward direction) is not activating. It shouldn't betoo difficult to trace down the circuit and find the faulty part but before I dig too deep I thought I'd see if anyone has a service manual for this thing. I've looked in the usual places on the 'net and haven't found anything, aside from Tony's notes for the interface. Thanks as always, Josh

Wanted - AT&T or Olivetti UNIX PC 3B1 / 7300 PALs, motherboard or system

by classiccmp＠philpem.me.uk

Hi guys, A few of you might be aware of my AT&T 3B1 (UNIX PC) emulator project, FreeBee: http://www.philpem.me.uk/code/3b1emu/ A few of you may recall my... less than flattering comments about the hardware manual. Long story short, the PAL equations in said manual are worthless. Too many logic terms are missing or incorrect. To that end, I'm looking for one of the following: A complete 3B1 system. Hard drive optional, I have a couple of ST506 hard disk drives here which could be pressed into service if need be. This would probably be cost-prohibitive unless the machine were already somewhere in the UK or EU (probably one of the units Olivetti imported, rebadged and sold). A motherboard and keyboard (and ideally the internal cabling). I'm reasonably convinced I could put together a power supply and some form of display, but the keyboard would be a pain to substitute. A set of PALs (labelled with their board position) and gate arrays (or the bodgeboards used in early-rev 3B1s) which I could read out and decode to produce a full set of logic equations. My main target is the Memory Mapper PAL. I'm not afraid of taking a "breaker" unit and fixing it up. Broken is fine, as long as it's something fixable (e.g. it dies during the poweron RAM test without ever displaying the AT&T startup banner). My plan is to dump the PALs and other programmable logic chips, then hook up a logic analyser and document the behaviour of the gate arrays (one of which is completely undocumented). If anyone has any leads on any of the above kit, please either reply here or contact me off list if you prefer. Of course, if you'd like to contribute code to FreeBee, I accept Unified Diff files by email, Dropbox or FTP :) Andrew Warkentin has done a terrific job of making it work >95% - it's just that last 5%. At the moment it boots the Foundation set install media to userspace but fails to mount the hard disc on /mnt, instead spitting out a "no space" error followed by several "no stack space" errors). The prior mkfs/install loader operations work fine... Thanks, -- Phil. classiccmp at philpem.me.uk http://www.philpem.me.uk/

FW: SCSI to IDE/SD Project

by LYNCHAJ＠YAHOO.COM

Hi More questions of a general nature. I am posting to CCTALK in case anyone else has similar questions. Overnight another $20 came in so we are closer! Thanks and have a nice day! Andrew Lynch -----Original Message----- From: Andrew Lynch [mailto:LYNCHAJ at YAHOO.COM] Sent: Friday, January 18, 2013 7:10 PM Subject: RE: SCSI to IDE/SD Project Thanks! Yes, the $22 is a prototype PCB-only just like the other builders would receive. The builders assemble their own boards (as would your) using their own components they source separately. The final cost of components ultimately depends on how the builder procures their components. The S2I project is meant for early SASI and/or SCSI-1 computers and equipment. It is not intended to replace SCSI-2 or later drives. SCSI-2 or later drives typically are still commonly available and/or commercial SCSI-2 to IDE solutions already exist. The S2I PCB includes a 50 pin dual row header pads typically associated with SASI and/or SCSI-1 internal drives. It could be adapted to a 25 pin external connector like those used on a Mac. It also has the 2mm spaced dual row header pads used on early Mac Laptop 2.5" SCSI-1 hard drives. Typical early SASI/SCSI-1 systems would be the original Sun-1 system, early Mac Plus, early Amiga, early Atari, etc. Usually these machines originated in the late 1970's to mid-1980's. Anything later than that is probably out of scope for this project and would suffer from its inherent limitations. For the builders next stage of build and test I intend to get 10 prototype PCBs which cost about $200. So far we've received $50 so only need $150 more. The theory you could get as many PCBs as you would like but the practical upper limit is less than 10 PCBs since the builders also need some prototype PCBs for their continued development. There is a lot of information posted on the N8VEM wiki in the SCSI to IDE prototype folder http://n8vem-sbc.pbworks.com/w/browse/#view=ViewFolder&param=SCSI%20to%20IDE %2FSD%20prototypes It is also discussed on the N8VEM mailing list. http://groups.google.com/group/n8vem If you are not familiar with the S2I project, I recommend you read the wiki and mailing list to get a feel for the project and what it entails. We are still in development and although the signs are promising we do not have full functionality at the moment. Thanks and have a nice day!

Selling off items to raise money

by sellam＠vintagetech.com

Fortunately, I was able to save for myself several surplus pieces that I had planned to sell to raise money back in December. I was never able to follow through because of the vortex I got sucked into at the time. Since I need the money now more than a shattered collection, I will proceed to sell these pieces. This is what I'm offering right now: Cromemco System 1 w/display, keyboard & (2) 5.25" floppy drives (might have functional hard disk with OS) Cromemco System Three Altair 8800a Altair 8800b Heathkit H11 w/H27 dual drives Teleram T-3000 portable with external 5.25" disk drive I'll get proper descriptions and photos and post them up tomorrow (Wednesday). I'm not terribly keen on shipping things internationally but I will with the right motivation. If you would like to make an initial offer then please e-mail me directly (off-list). I'll take best offers by this Friday. Since I'm motivated to raise a few thousand dollars within the next couple days I will entertain all reasonable offers. Thank you for your consideration. -- Sellam Ismail VintageTech ------------------------------------------------------------------------------ International Man of Intrigue and Danger http://www.vintagetech.com Whatsoever a man soweth, that shall he also reap...The truth is always simple.

Evans & Sutherland PS300 tapes

by derschjo＠gmail.com

While digging through a box of old VAX CompacTapes I found these two tapes >from Evans & Sutherland: MICRO-VAX HOST-TAPE: VAX/VMS Backup File: PSDIST.BCK Rev.: A2.V01 PS300 VAX HOST COMPACTAPE Format: VAX/VMS Backup Format Files: USER.BCK, TOOLS.BCK, DEMOS.BCK Part Number: 904003-040 Rev. Level: Illegible I do not know whether these two tapes still contain what they say they do, but if there's interest I can dig out my external TK50 and make an attempt to read them. The PS300 looks like a pretty interesting system. - Josh

SCSI to IDE/SD Project

by LYNCHAJ＠YAHOO.COM

> To: LYNCHAJ at yahoo.com > Subject: SCSI to IDE/SD Project > > Have you considered doing this as a Kickstart Project? > > I know I'd contribute if I could get a couple units... > Hi I got a couple of ideas/suggestions from a person on CCTALK in response to the S2I project. Given the small amount I would like to raise to buy the 10 prototype PCB boards ($150 max) I don't think it warrants the overhead of a Kickstarter project. This is more of a "pass the hat" among friends/fellow hobbyists sort of deal. I believe community support for S2I is essential. If you support the idea of a free/open source SCSI to IDE/SD bridge board even if this particular board is not for you please consider donating a small amount for the builders to get PCBs to support the project. Another idea is actually just buying one or more of the S2I PCBs. That would be just fine. Each prototype PCB would be $20 each plus shipping (typically $2 in the US and $5 elsewhere). You could support the project and I will send you a PCB. You could even buy two PCBs, one for yourself and another for a builder for build and test phase. Either way helps the S2I project by making the prototype PCB manufacturing economically feasible. Good ideas! Thank you! Have a nice day! Andrew Lynch PS, the topic of SCSI to IDE/SD has come up on CCTALK numerous times in the past. I know this will be a more pressing issue as the remaining SASI/SCSI-1 drives slowly fade away. http://www.classiccmp.org/pipermail/cctech/2009-January/062296.html http://www.classiccmp.org/pipermail/cctech/2010-November/080118.html

ASR 33 Teletype in Southern California (US)

by dan＠ekoan.com

This message appeared on the Greenkeys list. It's not mine and I'm on the opposite coast anyway, but for those of you looking for a classic I/O device at a less-than-eBay price, this may be of interest. Please contact Jason directly. ---------------------------- Original Message ------------------------------------ Subject: 33 ASR for sale, Burbank, CA Hi all, I am in project-reduction mode. I'm not going to do anything with this 33 ASR, or I should say, I haven't done anything with it, so I'm offering it for sale. I'd be thrilled to get my $40 back out of it. Pictures of it when I got it, looks exactly the same, starting here: http://www.flickr.com/photos/kf6pqt/page3/ I can reassemble it back into a single unit, or leave it in its state seen, depending on preference of the new owner. I will be selling junk out at the Chino Hills swap meet tomorrow morning, I'd prefer NOT to bring it with me, but if that's what it takes to get it into your hands, and $40 into mine, I can alter my preference. Thanks and 73, Jason W6IEE w6iee.811a at gmail.com
