Black screen on C64; continuous IRQ from VIC?

by fraveydank＠gmail.com

Hi all, I bought a C64 marked "non-working" at last year's VCF East as a project machine. Alas, I wasn't able to make it to Bil Herd and Rob Clarke's session on Commodore maintenance at the same show, so perhaps I missed this part. :-) Anyway, the screen is totally black, but it is syncing. I've verified on my scope that the VIC is generating the proper NTSC vertical and horizontal syncs, as well as the color burst, but there's no content. On further inspection, I've found that the IRQ line is pulled low as soon as the reset line is released, and it does not release. If I pull the VIC chip, the IRQ does not do the same thing. I know better than to assume correlation is the same as causation; it's entirely possible that by pulling the VIC, I've caused some crash in the initialization sequence that would cause one of the CIAs to pull the IRQ line constantly or something of the sort. I'm a Commodore newbie, so I don't know how the thing is *supposed* to behave, but I do know that a constant low on the IRQ line is going to keep the CPU from doing anything terribly useful unless it's masked. Anyone have advice? Is my VIC blown? I sure hope not, because those things are not easy to find outside of finding a scrapped C64. - Dave

drivers and software

by sales＠elecplus.com

I have about 50 pounds of old software, driver disks, motherboard disks, etc. Is there some site to upload these to, that is not full of junky ads, trying to get you to buy misc crap? I would love to share them with the community, but I don't know where to upload them? Drivers range from old video and sound cards, almost every HP deskjet there ever was, to current motherboards, etc. Software ranges from Windows 1.0, AutoCad 13, and lots of other misc stuff. Large selection of shareware/freeware for 8088 on up. Sorry, there is nothing that is not PC or Mac related, that I know of.

The mailmain service and the inbound/outbound mail seems to be working ok on the new server at the new datacenter. However, it's using the front-end at the old location, and it needs to use the front-end at the new location. I'll start working on that right now... yes... further traffic interruptions.

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...

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.

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

SCSI to IDE/SD project

by lynchaj＠yahoo.com

Hi We've made some real progress on the SCSI to IDE/SD project (aka S2I). It is a completely free/open source project entirely volunteer community project. By hobbyists for hobbyists! There have been many improvements and fixes found in the build and test that I've incorporated into a second version of the hardware board. Many thanks to our friends at SEBHC project. I estimate it will cost about $200 for another batch of prototype/pre-production boards. So far we've raised about $50 thanks to help from 68kMLA friends. We are constantly looking for additional developers. If you would like to help develop the S2I project to support your particular application please contact me. In particular, I would like to see development to support the very oldest SASI and/or SCSI-1 systems with unique requirements. That would demonstrate the benefits of customization of a free/open source project a commercial product never could/would support. Also if you would be interested in sponsoring our next batch of boards please contact me. Even small contributions would be greatly appreciated and help us toward a new set of boards. I would really like to reduce the cost burden to the builders who are already contributing their time and skills to help make this project available to everyone. Even if you disagree with this particular implementation of a S2I bridge board, the project is useful to the larger hobbyist community because it is creating valuable design information and source code which can be used in subsequent follow on projects. I have ideas for additional improvements and other applications but we have to get past this initial board hurdle first. Like all the N8VEM projects, all the information hardware, software, parts list, BOM, build instructions, photos, etc will be publicly posted and freely available to anyone. S2I is the only free/open source SCSI to IDE/SD project I am know of that's gotten to this stage. Please consider supporting this project. If you would like additional information you can reach me at LYNCHAJ at YAHOO.COM There is additional information on the S2I project at the N8VEM wiki http://n8vem-sbc.pbworks.com/w/browse/#view=ViewFolder&param=SCSI%20to%20ID… Discussion on the S2I project is on the N8VEM mailing list http://groups.google.com/group/n8vem Thank you in advance for your consideration.

server migration

by jwest＠huey.classiccmp.org

Ok, all the data for the classiccmp.org subdirectories has been moved. I will be switching the A record for classiccmp.org to the new server sometime today. I'll announce after it is done, and at that point people can again start modifying content of their sites whenever they wish. Important to note... I have not migrated the mailman/email stuff for classiccmp.org yet. That means several things... Once the website is moved, it will appear that the archives are not being updated or unavailable. Fear not, nothing is being lost. All the mail goes to the 'old' server and thus won't show up in the list archives. Whenever I move the mail, then the archives will automatically re-appear with all the traffic. Our front-end mail systems are not yet proven, so classiccmp will be the first test of that new infrastructure. Given the complexity of the new environment, this will be "target rich" for "issues". I will do the best I can as quickly as possible to resolve any issues. Best, J

I don't know or want to know what a bromide is even (sounds like something mum or dad were taking for gas or constipation back in the dawn of time, circa 1972).

FW: [N8VEM: 15283] Re: SCSI2IDE Progress

by LYNCHAJ＠YAHOO.COM

Hi! I think this is of general interest to the vintage/classic/hobbyist computer community. We are getting very close to a fully functional free and open source SCSI-1 to IDE (including CF adapters) and SD bridge board. There have been several discoveries during the build and test phase and we will be getting a second set of prototype boards soon that include all the fixes (including optional terminating resistors, various fixes and improvements, etc). Please see the photos of the test harness and the board responding to a PC SCSI-1 controller identify command. This board is being targeted to the most oldest SASI and/or SCSI-1 equipped machines. Generally speaking newer SCSI drives are still available and/or commercial SCSI to IDE bridges exist already so this board would not be necessary. It is primarily intended for the most ancient SASI/SCSI-1 machines such as early Mac, Atari, Amiga, Apple II, DEC, Sun, Apollo, various CP/M single board computers, sewing machines, synthesizers, lab and/or test equipment, etc with specialized SASI and/or SCSI-1 requirements. Occasionally these older machines require specific SASI and/or SCSI-1 drives to operate which may no longer be available. Since the bridge board is free/open source the identification strings and/or firmware can be modified to emulate these older devices. Thanks and have a nice day!

First, what a horrible, horrible thing to be going through, Sellam. I can't imagine the stress and shock you must be enduring right now. Like several people have said, despite your preferences on the matter, you really do need a pit-bull "good old boy" lawyer to go out and get this matter under control asap. You need to do this pronto. Only a good ole boy can work things out with good ole boys. You need a lawyer well connected, who golfs with the judges, etc. The more expensive, the better (unfortunately but true). Next, did you have insurance on your facility? If so, I presume you've contacted them? Ideally, if you had insurance, they'd fight the entire battle for you. If you did not, this will stand as an extremely painful lesson in the risks of not carrying it. I don't know you at all, but I feel for you. Things like this don't happen because we want them to or really through negligence.. they just sometimes are forced upon us by circumstance. Sell, sell, sell. Get money. Get a lawyer. You will not win this by yourself.. and if you are in a highly conservative area, even just your name (sadly) is going to hinder you. Best of luck. John S.

I've Retr0Brighted a handful of my computers in the past but now they seem to be regressing back to their original mellow yellow. This despite being kept in dark boxes. While UV seems to be essential for yellowing in the first place, perhaps it's not required for reyellowing/regression after a Retr0Bright treatment. Anyway I thought it was an interesting phenomenon worth sharing so I wrote an article on my experiences http://www.classic-computers.org.nz/blog/2013-01-15-retr0bright-only-tempor… Has anyone else observed this?
