Atari / GEM docs Free to good home (York, UK)

by pete＠dunnington.plus.com

These are primarily for Atari ST, mostly photocopies in A4 ring binders, to go as one lot: * ISV Development System documentation for Atari 520ST includes BIOS listing and more. ring-bound The following items were probably provided as part of this... * Listing of GEM "hello" program (GEM sample desktop accessory) Module: HELLO, by Tom Holander, Digital Research Feb 1986 ring-bound photocopy * Atari ST BASIC Source Book, 1985 ring-bound, printed original * Atari Logo Source Book 1985, small spiral-wire-bound published copy * GEM PRogrammer's Guide - Volume 1: VDI GEM PRogrammer's Guide - Volume 2: AES 1985, Digital Research, ring-bound photocopy * GEM DOS 1.0 Spec Version 13 May 16 1985 Digital Research "DR Confidential: Internal Use Only. Not to be copied or given to customers." ring-bound photocopy * "The Long-Awaited 'Line-A' Document" describes "quick-and-dirty" graphics access using 68000 Line A exception. Ring-bound with GEM DOS 1.0 Spec * ST Series BIOS Rev.A 2/13/85 (Atari 130 ST and 520 ST) "Atari Corporation Confidential" Ring-bound with GEM DOS 1.0 Spec I need to move these before Saturday 17th September (2 weeks from now). If they're not claimed by then, I'll donate them to The Computer Sheds (http://www.computermuseum.org.uk). Because of the weight, it would be expensive to ship these things, though if anyone is really keen I'll consider it. Collection from York would be greatly preferred (tea and biscuits supplied) - or I can probably take them to the DEC Legacy Event in Windermere for collection on the weekend of 15/16th October (pay for your own tea and biscuits). -- Pete Pete Turnbull

RC2016/10 COMPETITION ENTRY IS OPEN!

by mark＠wickensonline.co.uk

RC2016/10 COMPETITION ENTRY IS OPEN! I am pleased to announce that Retrochallenge 2016/10 ? the ?October? edition of the Retrochallenge - will run and is now open to entrants! Roll-up Roll-up! Get those thinking caps on and come up with an excellent retro-computing project. Why not? The Retrochallenge 2016/10 competition will run from October 1st to the end of the month. Blog entries should be complete by midnight on Monday 31st October GMT. I would like to extend the warmest welcome to the fantastic John W. Linville who is taking over the running of the October competition and, if he gets the bug, make take the reins for future Retrochallenge Competitions. If you would like to enter please email john using the address ?linville @ /tuxdriver.com?/(removing spaces)//with your name (or handle), a brief synopsis of your project and a URL for your blog. See the website http://retrochallenge.org for more details. ABOUT RETROCHALLENGE In a nutshell, the RetroChallenge is a loosely disorganised gathering of RetroComputing enthusiasts who collectively do stuff with old computers for a month. The event is very much open to interpretation? individuals set there own challenges, which can range from programming to multimedia work; hardware restoration to exploring legacy networking? or just plain dicking around. It really doesn?t matter what you do, just so long as you do it. While the RetroChallenge has its competitive side, it?s not really a contest? it?s more like global thermonuclear war ? everyone can play, but nobody really wins. COMPETITION RULES 1. Retrochallenge commences 1st October 2016 and runs until 31st October 2016. 2. In order to qualify, computer systems must be vintage (this used to be defined as 10 years old, but typically ?vintage? is older than that now ? don?t expect to be accepted if you are using a box capable of running Windows XP for example!). Exceptions will always be made for exotica! 3. Gaming consoles and PDAs qualify if they were made in the previous century. 4. Where appropriate, replica hardware and emulators may be used. 5. Entrants are responsible for adequately documenting their projects and submitting occasional updates during the contest, preferably with an announcement on twitter with #retrochallenge. 6. Projects may encompass any aspect of retro-computing that tickles the fancy of the individual entrant. 7. Winners will be carefully selected and adulation bestowed. 8. Have fun!

Wanted PATA HBA and IDE/UDMA Drive

by t.gardner＠computer.org

Hi: Looking for a PATA HBA (PCI, EISA or ISA) and if available an associated ATA/IDE drive preferably UDMA/33 but no faster than UDMA/100 This would likely be found in a PIII Pro or earlier system built prior to 1997 (I think the Natoma 440FX PII was the first to integrate IDE into the Southbridge) It might be from a later system as an expansion add in. This maybe a repeat request but I don't recall seeing my first request posted to the list - sorry if I'm wasting time. Any reasonable offer will be considered. Thanks Tom t.gardner at computer.org 650 941-5324

X Windows System Design Principles, a lecture by James Gettys

by tlindner＠macmess.org

I think it is dated 1988. https://www.youtube.com/watch?v=KdmNHM9BKY0 Interesting fact: His name is Gettys. Interesting quote: "We should never have done [the] Arc [drawing command], we should have done some spline implementation." -- -- tim lindner "Proper User Policy apparently means Simon Says."

How to build an ASCII CRT terminal, circa 1967

by aek＠bitsavers.org

Magnetorestrictive delay lines and a charactron. http://bitsavers.org/pdf/rca/terminal/70_750/70-01-752-U_Model_70_752_Video… We got one (no keyboard) a couple days ago with the manual. I'm still cleaning it up. It had something nesting in it and the inside has sunflower seed husks in it. It was made with plastic DIP ICs, no idea of the logic family. The keyboard was made by IBM, don't know what character code it produces. Pretty funky if it encodes ASCII.

BA123 Side panels and Stuck TK50

by shadoooo＠gmail.com

Hello, > The same cabinet has a TK50 and I foolishly put a cartridge into it and > now it won't come out. It is called being 'stuck'. How do proceed to > get this TK50 cartridge out? Error 'stuck' means that the tape has been "glued" to the head because of the effect of the tape binder being converted to adhesive due to age and moisture. You can remove the cartridge in this way: - pull the drive out of the machine - carefully unscrew the metal cover over the internal reel and the head to expose it - slowly insert a paper sheet between the tape and the head, in the same direction of the tape, to detach it without damage - slowly rotate the front motor (from bottom side) in way to rewind all the tape from the back reel to the cartridge reel - detach the tape leader if necessary - now keep the electromagnetic cartridge unlock mechanism pressed, and remove the cartridge from the drive A tape in this condition of striction is probably unusable anyway, unless you back it up a little in an oven, but even so it could be readable just for a couple of hours > Also, the TQK50 controller never saw the drive and I was wondering if > the PROM's (after 30 years) on the board lose their data? Well, I never seen an UV-EPROM loose it's data, unless the erase window cover is missing and the memory exposed to the sun light. Andrea

BA123 Side panels and Stuck TK50

by dj.taylor4＠comcast.net

This is real trivia but I have a BA123 cabinet (MicroVax II) and there a screws that hold the side panels in place, and mine are missing. Does anyone know the type of screw I should go look for at the hardware store? The same cabinet has a TK50 and I foolishly put a cartridge into it and now it won't come out. It is called being 'stuck'. How do proceed to get this TK50 cartridge out? Also, the TQK50 controller never saw the drive and I was wondering if the PROM's (after 30 years) on the board lose their data?

It's Terminal Week on RetroBattlestationst

by fozztexx＠fozztexx.com

It's Terminal Week on RetroBattlestations! https://redd.it/500myn This week is about those devices that you connect to a computer so that you can read output and provide input through a keyboard. The oldest terminals used paper for the display, and in the mid '70s the "glass TTY" became much more common. In the early days terminals had very little smarts in them. Some were electro-mechanical, later they had some circuitry, and by the late '70s almost all were using microprocessors inside. In fact if it weren't for a terminal company, Intel wouldn't have designed the 8008 microprocessor, the grandfather of the x86! Terminal Week is from August 28th to September 3rd. To participate in the contest you need to make a new post to RetroBattlestations of a picture or video that you shot of a computer terminal for this contest. At the end of the week 2 winners will be selected based on the oldest/newest setups as described above and will receive custom flair. In addition to the flair winners 3 other winners will be randomly selected. Each winner will receive their choice of two retro stickers: http://imgur.com/a/iAS5T -- Follow me on twitter: @FozzTexx Check out my blog: http://insentricity.com

I don't have anything that'll be competitive with the teletype guys but I'll enter anyway. ?For clarity.. does my CT1024 count as a terminal even though it does not possess a dedicated screen?
