A Complete History Of Mainframe Computing

by lproven＠gmail.com

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

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

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

To the Administrator I have given the equipment, tapes and paper documentation to Scott Kevill ( scott at kevill.com ) because he lives in Perth and was able to come pick it up. he has told me he plans to scan the paper material and put it on the web somewhere so others can see it. I was amazed to have 4 people contact me with a couple of days. thank you for spreading the word thru your mailing list - can you now notify all that the machine has gone to a better place :) , with an enthusiast.

Another Online Source for Diskettes

>>>> On Thu, 18 Apr 2013, Cory Smelosky wrote: >>>>> Btw, anyone have any blank 5.25" floppies kicking around? ;) For another source of diskettes, I've had good luck recently (end of last year) ordering from http://floppydisk.com/. It was a test buy of ten 5.25-inch hubless diskettes for $10 + s&h to format for use with DECmates by using a mix of old software, PCs, & TEAC drives. Health issues put that project on hold unfortunately. :( Floppydisk.com has 3.5-, 5.25-, and (at the time and maybe still) 8-inch diskettes with all of the standard storage capacities. Bulk purchases, obviously, reduce the cost per diskette. [I have no business relationship with them -- I'm just a happy customer.] Bob

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!!

by earl＠baugh.org

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.
