IIfx memory

by teoz＠neo.rr.com

Anybody know where to get memory (4mb simm or better) for a mac IIfx cheap or have some they dont want. I think its 64 pin proprietary memory (also used in a specific mac printer cant recall). Its funny how apple makes proprietary memory for only 1 specific model computer (how is that cost effective?), just like the memory upgrade for my apple 4/600 PS laser (one of a kind).

IBM System/36 - Advice Needed

by martinm＠allwest.net

This afternoon, I hauled home an IBM System/36 - PC (5364), complete with dedicated IBM PC (5150), Monitor, KB, cables and an IBM 4224 printer, but no documentation, all from my local Farmer's Insurance agent. The system is complete, including the "Farmers Master System Diskette". The components are badged "Farmers Insurance Group 5280Z". Googling indicates that these systems were fairly common. The system boots to the Service Control Menu, then continues the IPL to a IPL Sign On menu. Does anyone know the Service password or the Backup Service password for the Service Control Menu? Does anyone know another way into this system? I am an absolute neophyte on this system, so any help, warnings, war stories, etc. would be appreciated. Thank you, Martin Marshall

OT? Supera and Diamond Multimedia support

by tothwolf＠concentric.net

I guess this might be slightly OT, and maybe a little bit of a rant, though lots of Diamond products are easily 10 years old or older... I just found out today that the massive archive of drivers and firmware that was on the the Diamond ftp server [ftp://ftp.diamondmm.com/] is gone. I didn't have the bandwidth to mirror it, but I sure hope someone here got a copy when I recommended months back (Modem/Supra thread) that someone archive it. The support page for Diamond products [http://www.diamondmm.com/support/diamond/] formerly contained links to files on the ftp server. It now has the following posted: S3 or Diamond Brand Support We no longer support customer service or warranty claims on any of our legacy products sold under the former S3 or Diamond brand. As we no longer manufacture these products, and have not for some time, our customer care and warranty claim call volumes related to these products are extremely low. Because of this, we made the decision to discontinue support for these products. If you are experiencing problems with your Diamond or S3 legacy product please contact an independent repair professional. We appreciate your understanding in this matter and hope that this change does not inconvenience you greatly. The above statement seems totally ludicrous, as how is "an independent repair professional" (which I think I more than qualify for) supposed to support these products without the files that were available on the ftp site? I put in a call to their technical support staff at (206) 515-1400, and when I selected option '5' for diamond products, it referred me back to the above support url, claiming that support files were available on the website. The phone system then hung up, and I called back again selecting the Supra support and 'other' products...same thing. I finally got someone on the line by selecting Supra support and the first and only product the phone system mentioned. I think it was option 4 and 1. Talk about a nightmare. Turns out, they've suddenly had a massive influx of calls from other slightly annoyed customers who still support and use all this "obsolete hardware." Personally, I don't see how hardware can be "obsolete" if it works and does exactly what you need it to. They also seemed to have no clue that older versions of firmware and such are very important when maintaining and supporting these things. The ftp server formerly contained nearly every version that had been released. Now its all gone. Some of these products were only a couple of years old too. If other hardware forums haven't had info about this yet, they probably will soon... If anyone else wants to call and ask questions, the phone number above should get you though to someone. I've asked them about returning the ftp site to its former state, as that would seem to be the best solution for everyone right now. -Toth

Ah, yes, that would be one of those drives suplied by a company who figured that you don't really need two 0V lines, and 3-core mains flex is cheap. I can add another to the "240-into-5 doesn't go" list. I ran the repair and engineering department for a large Acorn dealer/distributor. One Saturday, a customer with his son bought a BBC B, Torch Z80 with disk pack, and a high-res Microvitec monitor; well over UKP1000 in those days. He was back on the Monday, looking very sad. His son had connected everything together before finding that the "mains plug" didn't fit. When he changed it, the fuse blew, so he replaced it and tried again :-( He was very nice about it, quite philosophical, and so we tried quite hard to rescue what we could, and find second-hand parts. We salvaged one of the two drives. We repaired the monitor. We found a spare BBC B board -- the original was deemed unrepairable. The disk pack PSU was a write-off, but we got the original Beeb PSU back from the shop. The Z80 board didn't look healthy, and he let us keep that too. Eventually, we stripped every IC and some other damaged parts off the board, fitted sockets everywhere, repaired several tracks with quite a lot of wire-wrap wire and epoxy, and it became a test bed. The Z80 got similar treatment, except it didn't need track repairs, and we turned it over to a teenager who was with us for work experience. We thought it would be good (de)soldering practice. He was delighted when he ended up with a clean board, and even more so when the fully-socketed version worked at the the end of it, so I suppose some good came of it all -- he'd apparently been something of a problem to the college tutors before he discovered there was something he could actually achieve. Those Torch Z80's were a royal pain. After that incident, we told the shops not to take out or replace the BBC supply under any circumstances, and eventually Torch stopped the practice of replacing the original PSU. The Beeb SMPSU was perfectly capable of running a fully-expanded machine with a Torch processor, so using Torch's rather inferior (but more powerful) unit was not a good idea. The Torch Z80 board is about Eurocard size, fitted with a short 40-way ribbon cable, and was supposed to be mounted in the lid of the BBC B, using four PCB mounts of the type that have self-adhesive pads. They used to fall off after a while. Now you might think that's just irritating (it's certainly awkward to fit correctly) but it's more than that. When it falls, it tends to short things out. Unfortunately, the regulation on Torch PSUs is very poor when they crowbar, and when the 5V rail comes back after it's shut down, it tends to overshoot -- by about 4 volts, according to our scope. TTL doesn't like 9V. I've seen at least two Beebs destroyed that way. One of them looked fine, but didn't work -- something of a puzzle, as the owner had replaced the original Acorn PSU and we didn't know he had been using the Torch one. It just went "tick-tick-tick", as they do when they're shorted, or as in this case, detect over-current. So we put it on a bench supply, thinking either to blow off a faulty capacitor or maybe find a hot chip. No, but it drew 9 amps (a Beeb usually takes about two) and after a little while it was obvious several LS TTL chips were cooking. So we removed them. Back on the PSU, still several amps over normal. A few more hot chips after a short while. And so it went on, until all that was left was the NMOS (all of which still worked). Another expensive repair. -- Pete Peter Turnbull Network Manager University of York

This greatly increases the surface area and gives a higher capacitance per square inch of foil. I have a radio that was made in the 50's. I brought the capacitors in it up slowly. I've checked them on my bridge and they are all above 45% of the labeled value. The radio works fine. Dwight

This reminds me of a true story regarding a BBC microcomputer. This was in the early 80s when a company called Torch produced an auxiluary processor for the BBC (I think so that it could run CP/M programs). Anyway the Torch was an external box that contained its own PSU and connected via a ribbon cable with the BBC micro, which served as the keyboard/display peripheral for the Torch. Early BBCs had problems with their own PSU (it overheated), so the Torch people removed the PSU from the BBC and used another cable to supply power *to* the BBC from the Torch box. Unfortunately, they used a cable that looked like a power cable. So when the BBC + Torch arrived, the genious who was responsible for assembling the kit, promptly added a mains plug to the power cable and plugged it in, feeding 240V AC to the +5 and +12V rails. I looked at that mainboard afterwards and a lot of tracks had melted! **vp

Look at my sig...you'll see where they've all gone :) I have a dozen or so Selectric, Selectric II, and Selectric III typewriters, mostly in various states of sticky disrepair. Actually, I don't have any Selectric terminals, although I do have a Selectric Memory Typewriter. My brother worked at a Byte Shop in the late 70s, and recalls having either converted a Selectric or making a conversion work. I do have a manual from 1962 titled "IBM Customer Engineering Manual of Instruction, I/O Printer, (Modified IBM Selectric), which shows the glorious workings of this fascinating machine...the manual has lots of text and diagrams explaining the Selectric mechanism, but not much in the way of photos showing the solenoid mechanisms. We were thinking a few years ago of trying to rig up a homebrew conversion of one of my typewriters, but never got round to it. But I did (in 1999?) see a conversion kit sell on ebay...and I was foolish enough to not buy it. -- Jim Visit the Selectric Typewriter Museum! http://www.mindspring.com/~jforbes2

Baydel were (are?) latterly quite well known for RAID systems; prior to that they made (amongst other things) QBus floppy controllers, to connect to SA800/850 drives. I have a couple of single-density ones that emulate an RXV11 or a pair of RXV11s. I'd guess this board is an emulation of an RXV21, to connect to SA800/850 drives. Power it up, and see if it responds to the RXV21 addresses. BTW, I found Baydel quite helpful when I wanted some information about mine (labelled F11-311) -- but that was a decade ago and I don't know if the same technical staff will still be there. -- Pete Peter Turnbull Network Manager University of York

openvms... another question

by jwest＠classiccmp.org

Ok, I know NOTHING about openVMS. However, this just came up... A friend of a friend offered me what he says is a complete set of OpenVMS media. No manuals, just the media. Several questions: >From what I understand, isn't there some type of hobbyist free license for openvms? If so, not sure why I should grab the media from him if I can just download it. Or is there a value to getting the media from him, as to it giving me the ability to purchase a license transfer or something... in short, is there a special reason getting "real" media is desirable? Lastly... he said it runs on vax's and pdp's. Not sure if he knows what he's talking about, so I'll ask here. Could this run on my 11/44? Thanks for any enlightenment! Jay West

!HELP!! ALTAIR BLEW SMOKE!!!

by stevenaleach＠mac.com

Well, I must say I'm rather amazed at how quickly I got a response. Within an hour of my post, two individuals (Steve Thatcher and Scott LaBombard) both provided the information on the tantalum cap, and I found the parts at DigiKey. Thanks guys! I'm so glad to see some hope at getting the Altair back up and running. When it sizzled popped and smoked, it was like an old friend had died. If you could humor my electronic ignorance, what exactly IS a tantalum cap and how does it differ from a normal capacitor? I was never before aware that there could be more to a capacitor than plates (or foil) and an electrolyte. How can a capacitor have a polarity? Another question, does anyone know where I can find a replacement for the two position front panel switches on the Altair which are marked "AMERICAN U.S.A ST1-1" These are 2 pos 3 contact switches, and I've not been able to find anything exactly the same dimensions. I am hoping that this is some standard switch and I'm just not aware of it :-) Also, I've come across rumers of Altair manuals online in PDF format. Does anyone know where I could find such a thing? I'm sure I'll have more questions once I get the poor machine put back together and start trying to figure out the disk drives and controllers :-) The machine was stored for over seven years in a barn wrapped in plastic bags (not my decision! Don't burn me at the stake!) I wonder how many more surprises I'm in for?

I was never before > aware that there could be more to a capacitor than plates (or foil) and > an electrolyte. How can a capacitor have a polarity? Almost all electrolytic caps are polarised. In principle, a tantalum capacitor is just like an aluminium electrolytic, only using a more exotic metal (tantalum pentoxide has a dielectric constant about 4-5 times higher than aluminium oxide) and a solid electrolyte. The anode is the foil (or bead, if it's sintered tantalum tantalum), the oxide layer on it is the dialectric, and the electrolyte is the cathode. Passing current from cathode to anode will build up the oxide layer, the other way will break it down. From a chemist's point of view, putting electrons into the cathode and taking them out of the anode makes some of the metallic aluminium (Al) ionise into Al+++, and if there are oxygen ions (O--) adjacent, it forms alumina (Al203) -- standard RedOx reaction, exactly the same as anodising aluminium for protection. You have to maintain the polarity to maintain the oxide layer; if you reverse it the electrons will break down the oxide layer. The aluminium ions would gain electrons, the oxygen ions would lose them, the alumina becomes aluminium and oxygen, and then you have no more highly-insulating aluminium oxide dielctric. Think of the aluminium-alumina junction as a junction diode, with a very high resistance in one direction and a very low resistance the other way.

Hi, > I got a nice NCD 17c X terminal a while back, but I don't > have the server software to download to it. Does anyone > have such software or a pointer to where to get it? If you just need the boot image, I think you're looking for a file called "Xncd17c" - I use Xncd19c for my 88k-based xterm (or did, last time I used it for anything!) These used to be freely available on ftp.ncd.com (up until 2 years ago for sure) in their own "older units" directory tree but seem to have vanished. However a quick google returned: http://www.stat.wisc.edu/p/stat/tftpboot/cs/Xncd17c ... which may be exactly what you need. Set up a tftp server somewhere with the image on and you're away :) cheers, Jules __________________________________________________ It's Samaritans' Week. Help Samaritans help others.

There are many techniques to avoid static displays. * Rotating the equipment on a turntable with the back open. * Recreating really old equipment or high wear parts. * Equipment displays with interactive java simulation of the equipment running nearby. * Faking the output display on unpowered equipment with the 'PC behind the curtain'. * Or just using equipment that is still some what available.

FAQ. This is the result of having a 9302 terminator, whichg asserts SACK, and a missing NPR jumper somewhere. Either you have a card missing, or you've put a card that doesn't pass NPR into a slot where previously there was a card that did (or you've put a small grant card where you should have a full-size one). Ethan mentioned this in response to one of your posts recently, and Tony (on more than one occasion) explained in detail why this has the effect it does. http://www.classiccmp.org/pipermail/cctalk/2003-May/022031.html http://www.classiccmp.org/pipermail/cctalk/2003-May/022051.html Don't feel *too* bad about it, I got caught myself with that, once. -- Pete Peter Turnbull Network Manager University of York

!HELP!! ALTAIR BLEW SMOKE!!!

by stevenaleach＠mac.com

I just retrieved an Altair 8800B from long term storage. I blew away the dust, checked for loose connections, and finally powered it up. Lights flickered to life, and then smoke poured from the front panel. I pulled it apart, and found a very crispy capacitor number C4 on the front panel card. My first problem is that this capacitor is so crispy that I have no way of determining the proper value. It is (was) connected to a voltage regulator marked "F 79MO8 AUC 7535"

ICL 2950

by classiccmp.org＠irrelevant.fsnet.co.uk

Hmm... Having seen this on eBay: http://cgi.ebay.co.uk/ws/eBayISAPI.dll?ViewItem&item=2731022229&category=12… the nameplate from an ICL 2950, weighing over 2Kg alone, and had my curiosity nudged, I was wondering if anybody knew of any pictures of the beast itself? A quick google found me a bit of info, but no pics yet. Hmm.. I've got a nameplate stuck to a 5.25" disc box in the cupboard from a Ferranti "EWTS" system (Early Warning [Tracking|Training] System, I forget which, and google doesn't help at all) ... Picked it up while I was an apprentice there - now that was fun, wandering round the factory, about 1982/3 - I seem to recall computer generated ships and stuff on one system. Amazing graphics for the time. It's a shame how little of the old stuff still exists.. I also used to "play" on a Data General Nova, must have been about 1980, at the college my Dad taught at; I sometimes wonder whatever happened to that.. Rob.

I am now using this e-mail address for all incoming e-mail. If convenient, please change the e-mail address that you use when you send me private e-mail. Note that all of the recent e-mail address will still be active for about a month, so if you don't do the change immediately, it will not be a problem. PLUS, this is a test that everything is working properly. The volume of spam finally became too large! Sincerely yours, Jerome Fine -- If you attempted to send a reply and the original e-mail address has been discontinued due a high volume of junk e-mail, then the semi-permanent e-mail address can be obtained by replacing the four characters preceding the 'at' with the four digits of the current year.

Where have all the Selectrics gone?

by swtpc6800＠attbi.com

I got rid of mine at a garage sale in about 10 years ago. (Before I started restoring my junk.) I had a Trendata1000, which was similar to the IBM 2741. It had a real IBM Selectric Terminal with Trendata's custom electronics. Many members of The Northwest Computer Society (Seattle) bought refurbished Trendata1000s from a local Computer Land store for about $900. Here is a photo of my Selectric Terminal and my SWTPC system in 1978. http://www.swtpc.com/mholley/MySystem/MySystemPhoto.htm I still have the IBM reference manual for the 2741 Communitations Terminal. It is 20 pages on how to write a driver for the 2741. I also have the documentation on how to connect it to a SWTPC 6800 with no special hardware. I normally used it for a printer but it also worked as a terminal. Here is a description of my computer that I wrote in 1978. http://www.swtpc.com/mholley/MySystem/MySystem.htm Michael Holley www.swtpc.com/mholley

PDP-7

by toresbe＠ifi.uio.no

We have 8 warehouses stuffed with mainframes and minis. Around 120 of them in total. This belongs to the Norwegian Museum of Science and Technology, and with so many machines, there's BOUND to be a -10 there too :). On average, the museum recieves a query for pickup once a week. They also ran a mainframe on public display 15-20 years ago, but this was a Norwegian machine (NORD-1 i think, brilliant machine) and the people who knew about it didn't have the time it took to keep the mainframe going. This machine has been upgraded to run PDP-9 software, and has a switch on the front panel named "USE" with the options 7 and 9. It also had a homemade Automatic Priority Interrupt, nicknamed "Poor man's API". It has an oscilloscope display, two TU55 tape drives hooked up to a 550 tape controller, and the EAE (Extended Arithmetic Element). Picture at http://tore.nortia.no . Yes, we have a full set of schematics, except for one board (and with godly precision, this is the one we need), the Teletype Interface Card, seated inside the teletype. It is numbered 1818(twomoredigits). If I restore this -7, the Museum might let me inside one of their warehouses, and maybe restore a timesharing system, like, for instance, a -10. But, I'm going to keep focused on this task (for now ;) My dream has always been logging on a timesharing system with a VT terminal. IF the warehouse has a 15 in it, i'll ask them very nicely for a TC15. Who knows. We do have tons of -15 documentation (ask me not why) at the University, and even some -15 OS DECtapes.

Hi, I saw a forum on line and your email was there. I was wondering if you could solve my problem. When I turn on system, the screen says turn off game before inserting cartridge. It does have the coleco logo so I know it has power and rf is working. I did what it said and I also hit the reset button but I get the same screen. I also cleaned the contacts on the cartridges. Do you have any idea what is wrong? Thank you for your time, Snickers48180(a)yahoo.com The New Yahoo! Search - Faster. Easier. Bingo.

Kaypro Corp. or Non-Linear Systems

by DABIGDOG143＠cs.com

In response to the question of which came first, Non-Linear Systems or, Kaypro Corporation. I worked in the purchasing department of both companies during the 1980s. Kaypro Corporation was a division of the parent company Non-Linear Systems which was established in the 1950s by Andrew Kay, who was the innovator of the digital volt meter. In the early 1980s, Non-Linear Systems began building the Kaypro portable computer after Kay's Son-in-law, Jonathan Badder, a local architect in partnership with Kay's Daughter Janice Kay, expressed a desire to have a portable computer to take out to job sites. When the Kaypro portable computer became an overnight success and far eclipsed the volt meter business, Kay established the computer division known as Kaypro Corporation. Both products were manufactured simultaneously at the Solana Beach, California location at 533 Stevens Avenue, near the Lomas Santa Fe exit of Interstate 5. When I joined the Company in early 1983 we went from about 50 employees to over 500 within a year. Andrew Kay was a very interesting and forward thinking employer, hence the name of his original company Non-Linear Systems, since he prided himself on non-linear thinking. He was a very health conscious individual, and had a juice and salad bar installed, which all employees could dine at for only a dollar. He tried to treat everyone as extended family, and believed that a work environment that incorporated nature in it's design would produce better work. Therefore, every office had windows in front and back, with a row of trees and grass between each building. It required some considerable walking to negotiate around the plant, but he believed that walking promoted good health. He also was very interested in personal intellect, and in the early stages of Kaypro, everybody had to take a sort of IQ test that he designed and administered. He also made versions of the Kaypro that were marketed as the "Tutor Computer" that were a learning aide for children. It was a fun place to work in the early days, with a very young average employee age. We were encouraged to work hard, and to play hard. Lots of parties, barbecues, intramural sports teams, and the like. It was fun to go to work everyday. During the push to increase shipments before the Company's initial public stock offering, we received some very generous bonuses, including a Christmas bonus equal to a month's salary, which we received around December 15th. In the latter 1980s the company was plagued by poor quality, serious inventory management problems, a revolving door on upper management that included a long parade of self-impressed no-nothings that couldn't break free of their linear thinking, and a serious lack of continued product innovation. After the big boys like IBM jumped on the bandwagon of the PC and laptop market, Kaypro just couldn't compete. All these factors and a few more, including the employment of Kay family members in key positions that did not have the capabilities of founder Andrew Kay, eventually led to the demise of Kaypro. I think that the business section writer for the San Diego Union Tribune said it best when he penned the phrase "Too many Kays and not enough Pros." Garr Farrell

Tube logic (was: HP nixie tube module)

I have a tube digital clock, which I made out of a Beckman Berkeley counter. The counter uses decade modules, each with four tubes used as flip-flops, and ten neon lamps which display the count on a numbered 0-9 plasic window. The HP modules work pretty much the same way as the Beckman tube modules, although the binary to decimal decoding scheme is different in that it uses light and photoresistors instead of resistor networks. http://www.mindspring.com/~jforbes2/tubeclock/index.html shows my clock. The counter modules could possibly be used as the basis for a tube computer...maybe. I have a bunch of extra modules. I believe my brother has the schematic for the HP counter that uses the nixie modules, and he has one of the HP counters. -- Jim Visit the Selectric Typewriter Museum! http://www.mindspring.com/~jforbes2
