A Complete History Of Mainframe Computing

Tom's Hardware - a popular site for PC hardware tweakers and overclockers - has done an ambitious article on the development of the mainframe: http://www.tomshardware.com/picturestory/508-mainframe-computer-history.html It's a little American-centric but it's not at all bad. -- Liam Proven ?

Talk to your spouse/partner. I live in Vancouver BC, but took a job in Halifax, Nova Scotia because it was a real opportunity and a "dream job" for me. These opportunities don't come up often. I was able to work out a generally-achievable "two weeks on; two weeks off" schedule, and commute to Vancouver to see my wife. The distance is tough, but there's Vonage/Skype for free calls, and I get home every 2 - 3 weeks, or at worst once a month for a week. Kevin

What are these Tektronix paper rolls? (8.5-inch wide, 3.25-inch diameter)

by glen.slick＠gmail.com

I have some boxes of Tektronix paper rolls and I have no idea where they were used. The rolls are 8.5-inches wide and have a diameter of 3.25-inches. They are packed 6 to a box and I have around six boxes of these which are all sealed except for one. I can't find any obvious part numbers anywhere. The boxes say Made in Japan and have JAL Cargo stickers on them and were shipped to PDX. These might date back to somewhere in the 1980's. They came along with some Tektronix 4170 systems I picked up a while back. Anyone know what equipment would have used these rolls? Are they most likely thermal, or something else? Anyone have a use for these? Would they still be suitable for the original application after 25 years? The boxes are a bit heavy if someone has a use for these and wants them. -Glen

Another Online Source for Diskettes

Available S-100 PCBs

by LYNCHAJ＠YAHOO.COM

Hi, an update on available S-100 board PCBs Good news!? There are several new and reordered S-100 PCBs available! The S-100 68K CPU boards finally came in so there are about 5 available. There are 25 of the S-100 IDE V2 reorder PCBs and 6 of the new S-100 bus terminator/prototyping board PCBs. There are 4 of the S-100 LAVA PCBs available. http://s100computers.com/My%20System%20Pages/68000%20Board/68K%20CPU%20Board .htm http://s100computers.com/My%20System%20Pages/IDE%20Board/My%20IDE%20Card.htm http://n8vem-sbc.pbworks.com/w/browse/#view=ViewFolder&param=S-100%20bus%20t erminator http://s100computers.com/My%20System%20Pages/Lava-10%20Board/LAVA-10%20Board .htm The S-100 PCBs cost the same as before ($20 each).? However due to unforeseen extreme price increases in shipping by USPS I am forced to change shipping costs. Shipping in the US will be $3 for a single PCB and $2 for each additional PCB.? Shipping internationally will be $10 for a single PCB and $3 for each additional PCB.? This is for the bare basics USPS first class postage with no tracking or insurance.? The builder assumes all risk of delivery as per usual arrangement. I apologize for the large price increase on shipping but this is out of my hands.? The USPS is in dire financial trouble and is raising prices on shipping.? It affects us all and is most unfortunate.? These boards are provided "at cost" so there is no margin to absorb any shipping price increases.? I have to pass them along. If you would like one or more S-100 PCBs please send a PayPal to LYNCHAJ at YAHOO.COM Thanks and have a nice day! Andrew Lynch PS, if you would like to help out this all-volunteer project please get one or more of the S-100 LAVA PCBs. These PCBs are the oldest ones and them sitting around on a shelf does no one any good. I?d like these to go to a hobbyist who would get some enjoyment from these fun to build and use boards. Thanks in advance. I truly appreciate everyone's support in moving these remaining boards. You make this hobbyist home brew project possible.

VCF Southeast this weekend!!

For anybody within driving distance of Atlanta this weekend, we have the first VCF Southeast this weekend. You can get info via http://vintage.org/2013/southeast/ or via the Atlanta Historic Computing Society site (http://atlhcs.org/) Directions, etc. are all there. We have a pretty impressive Apple Pop-Up Museum that you begin with (Pop-Up doesn't mean it's made of paper and pops up when you turn the page, but rather that it's here for this weekend, and may "Pop-Up" somewhere else later on..) A chance to see some fairly historic pieces of computer history and hear some interesting speakers... Earl Baugh (AHCS member)

Computing the old way - Is it a thing of the past?

by c.murray.mccullough＠gmail.com

Should we be surprised at how and why classic-computing, this site in particular, is so popular amongst the hobbyist/experimenter community today? There is a modicum of control that?s lacking in today?s computing, or computing-like, technology. Granted it?s ?easier? to use/employ, nearly by all; everything, or almost, done without consumer input but turning the infernal beast on. Or, maybe not with the ?intelligence agents? been employed today! And even our computers I dare say going this route. Automatic updates, etc., etc., happen?Making a computer or otherwise do what you want it to do, rather than say an Apple or something akin, is fast becoming a thing of the past. Freedom. Let?s hope it?s not pass? either! Murray--

Thorny diagnostic issue for an Epson QX-10

by terry＠webweavers.co.nz

Symptom: A QX-10 keeps shutting down, but at random and in an erratic way. By erratic it will sometimes shutdown--Start---Shutdown--start---within a 1/2 second of each sequence. It sounds like there is a short somewhere or at least some component failing. But where? Its hard to diagnose because (1) It's intermittent and (2) I don't want to run the machine when it's flip flopping on and off. That's definitely not good for the components. I've determined that it's either the PSU or mainboard at fault. Both are for sale on e-Bay. However, I don't whant to buy both when only one is the problem. Any ideas how I might determine which? The PSU doesn't not fire at all if there is no load on it. Terry (Tez)

H780 power supply

by abacos_98＠yahoo.com

Started tearing into the 11/780 and pulled the 11/03 and the RX01 out to clean and test. Looks like the PS is bad in the 11/03. It powers on and the fans run because they are AC but I am getting sometimes 4.5 volts on the 5v line and 0 volts on the 12v. I have 34 volts coming out of the diode rectifier. I suspect switching transistors. Anyone have experience with these? Brian.

Whatever it is, one way to approach it is to make a dummy load for the PSU which resembles the normal load on it as far as possible. If the PSU continues to malfunction when feeding only the dummy load, the problem is almost certain to be in the PSU itself. Dummy loads for low voltages can often be made from bulbs for use in cars, including dual filament bulbs which had to be replaced because one filament failed. Another useful thing to do is to look for bad connections in the PSU. If it is constructed on a printed circuit board, while feeding the dummy load, try examining the underside of the board in a darkened room while tapping the board with something insulated. You might see or hear tiny sparks indicating the location of a bad solder joint. Be aware that the PSU probably contains high voltages and that these may remain for a considerable period of time after power has been removed, particularly if the unit is faulty. Regards, Peter Coghlan.

Exidy Sorcerer available in Australia

by nospam212-cctalk＠yahoo.com

Was contacted by the person below looking for someone in Australia interested in an Exidy Sorcerer. Passing along here. Contact the person below. I would be interested in possible copies of any doc or such which I don't have for my Sorcerer if someone picks this up. David Williams www.trailingedge.com ----------------- I am in Australia. Do you have a contact here that would like to have it for collection or museum? it WAS a 48K memory version but in later years of use the memory dropped to 32K - presumably a meory fault or dry joint somewhere. Unfortunately, I cannot tell if it is still working, because I have lost the connector cable for the video to the modified TV which Dick Smith electronics sold with it. I also have about half a file drawer of documentation related to it and related matters. Cheers...

8mm Movie to Digital Service?

Look around for a coupon / Groupon, they do have discounts and frequent promotions. I think this digital scanning of old film is entirely apropos for computer preservationists. Many early computer animations were recorded this way. It seems like many film-to-digital conversions happened by way of steps that involved NTSC video. That's a shame, and reminds us of the lesson of the value of keeping the original material. - John

I remember when I was doing my thesis, I printed it on the department's Qume daisywheel printer. They had the service manual with complete schematics. It was very interesting, with analogue servos for the carriage motor. A very nice piece of equipment. Not to mention the 11/40 we used, or the big 80 MB Ampex disk drives. /Jonas

Computing the old way - Is it a thing of the past?

I recently had some old (1940s to '70s) 8 mm family movies scanned digitally. The service cleans the film and uses a wet-gate process to reduce scratches. They scan each frame digitally at HD resolution (1920 x 1080) using even LED illumination. They scan the entire film edge-to-edge. Many old cameras exposed the entire width of the film while the projector only showed the majority of the middle, so you see more image than ever before. I asked for a digital movie file for editing, so I sent them a hard drive. The results are astoundingly dramatically better >from what you got from an old projector. No playback jitter >from worn sprocket holes. Bright, even illumination. It's far better than the film-to-VHS transfer I paid for in the early 90s. (Private YouTube example links available on request.) All this for a dime or two per foot. I'll be able to edit digitally and provide family members with DVD or Bluray copies. The same is true for restoration and duplication of old family photographs. With a digital process, you can undo damage and easily multiply copies. As with the classic computer avocation, it can come with regrets, too. I wish I would've rescued 1930s family films from a distant cousin who passed away a decade ago. I had a VHS copy of some of his films, but not the originals. - John

Data General Dasher D200 Manuals

I've looked in all the usual places and can't find any manuals for the D200 - does anyone have a scan? I know there are manuals for the later D410 and D411 floating around - but I would like to get some definitive details on the D200. (Also - still looking for any help with the MV/2500...)

I find hardware and system software (operating systems, database managers etc) equally interesting. Actually, my view is that they are to a great extent two different incarnations of the same thing: The hardware is a physical machine that executes programs, the operating system is a kind of virtual machine which executes user programs. Then there is virtual machine software, that is also very interesting. I wrote a very simple operating system once in my career, now I am playing with writing another one in my spare time. Some day I will most likely also design and built my own processor, whether with discrete logic or an FPGA I am not sure, perhaps both. And then the physical experience of an actual old machine running is something special, quite like driving an old car or riding on a steam train. /Jonas

First, thank you to everyone who replied. I got at least something out of every post so far and that's no small thing. I must have misread something along the way as I thought the /23 had separate I/D spaces. Good thing to have that correct now. I'd not mind getting one to run it for it's own sake but to get it thinking it could do something it couldn't would be much more annoying. Thank you to the pointers to additional docs - the field guide as especially nice to find as I'm still learning my way around the DEC module names. The chassis information was quite helpful as well. As for why, well... I graduated HS in 1982 & took a short detour into the Army so I missed a lot of the "glory days" of some of the things on this list. I started with micros and as a student the closest I got allowed to the Vax was a login prompt. The first (non DOS,OS/2,Windows) software environment I really got to know well was Unix and then learning of Lisp & LispM's. These days emulators are fun, capable and perfect for most home users - I certainly would not have the room or power budget for a CADR or PDP-10 or 11/780 in the basement! I respect those who can but, alas, I'm not able to do that in my current rental But I do have the room and enough of a toy budget to slowly put together a classic PDP-11 system of the later /73, /83 or /93 type & run the kind of software I'm familiar with on it. Might even try to see if I can back port Franz lisp and to it from the 4.2 distribution just to give myself a reason for it. Ultimately I'd like to have a small collection of real classic hardware - a Symbolics XL1200, a Vax (or Vaxstation) 4000 & a PDP-11. I'll work on that last one for now and deal with emulation for the rest :) Thanks again to everyone, William -- Live like you will never die, love like you've never been hurt, dance like no-one is watching.

Warning: fake ebay 'second chance' offers

by tmfdmike＠gmail.com

Folks, I was an underbidder on the System/360 panel that recently went on ebay. This morning I received an obviously fake 'second chance' offer email. The interesting part is that the sender had clearly done some research, as ebay has not exposed your email address for many years, precisely to prevent scams like this. Since my ebay ID is 'corestore_org' it's not too hard to google and find an email address for me; they clearly did so, as the email correctly associated my email address with my account name, exactly as a genuine ebay email would. I don't think anyone here would be taken in by such for an instant, but be warned all the same; someone is being 'active' with scams tailored to our interests. The email claimed to originate from 'ebay at ebay.joe211.info' and sought a reply to 'jrengineer70 at gmail.com'. EDIT a google reveals several other scam emails using this email address. It never struck me before, but of course ebay doesn't even show underbidder *account names* any more; they splash them with asterisks and display them as x******x. Yet the scammer knew my full ebay ID, my correct email address, AND the amount of my underbid. Someone *must* have cracked the ebay database...
