Hello all! I've tried to sign up for cctalk several times over the years, and never had a successful registration. Seems this time worked. I'm Jonathan, glitch on some other lists and forums, I'm the one responsible for glitchwrks.com. I hack on old computers, pre-PC stuff, mostly S-100, PDP-11 (largely QBus), and Ohio Scientific. I do industrial systems engineering/repair, legacy systems support, and server-side programming for $day_job. Also starting to get into *selling* some of my hobby designs as kits. Thanks, Jonathan

Q Bus Music Board

by pontus＠Update.UU.SE

Hi This has been discussed on this mailinglist before (back in -95 and -03). But with very little information came out of that. I'm curious about the "Q Bus Music Board" that DEC made. What system was it used in, what software was available that took advantage of it, how would you program it? All I know is from the cctalk threads and a few pictures from an ebay auction, with missleading description, that I missed out on. The number on the green handle is "93 08036" and on the PCB there is the number "EY-0105E-MS-0101" and it looks like it has two AY-3-8192 synthesiser chips. So, does anyone know anything more? And if anyone has one they could part with, I'd be interested. Kind Regards, Pontus.

Reading PALs

by brain＠jbrain.com

Seems like someone on list was willing and able to read PAL16L8s and give a try to some PAL16R4s... Is that person still on list and still interested? If so, please contact me off-list. I am trying to restore some C64 carts, and the PAL on my working unit is protected, so I cannot replicate. Jim -- Jim Brain brain at jbrain.com www.jbrain.com

New batch of pdp8 OMNIBUS to USB interface! Please Read and react!

by hachti＠hachti.de

Hi folks, it has taken a while but I'm now actively planning to shift out another batch of OmniUSB boards. The last batch is sold out for a long time and I've been asked for more from time to time. As some of you might remember, it's a cool device to connect your pdp8/f/a/m/e to the modern world using lightning fast USB. The originial board has it's website here: http://pdp8.hachti.de/projects/omni_usb/ The new board will do the same, perhaps even more. - the USB connector will be replaced by a mini (NOT micro!!) USB connector. - The connector position and cable routing will be improved. - The board will be shorter. But it will come by default with a laser cut acrylic extension that makes it full size again. There will be at least those options to buy: - Kit (board + all parts) - Kit+ (board + all parts, SMT already assembled) Possible: - complete version - Everything soldered and tested. - discount for omitting acrylic extender I cannot guarantee that I can deliver fully assembled boards (regulations) and would be able to do that only if there's a reasonable number of interested buyers. If have set up a doodle poll to get a realistic picture of the interest in the board/kit/device: http://doodle.com/poll/d7y524mvyfezqp9w PLEASE take the minute and fill in your name (ideally that I can recognise you) and check the options which most precisely match your demands. PLEASE be as honest as possible as I will base my decisions IF and for which PRICE I can run the show. Thank you!!! Kind regards Philipp :-)

DISSPLA fortran source anyone?

by rdawson16＠hotmail.com

The scientific graphics software package, written By Ian Hirscholn. Later sold to Coumputer Automation. He ported it to the PC later, with his company ISSCO. They also made a neat bitslice machine to run it, the Portable Graphics Mainframe, I had one for a bit, I was their rep. Anybody have anything on this beast, it was amazing. Randy

DATARAM DR-118 docs?

by w2hx＠w2hx.com

Hi folks, Looking for documentation on the DATARAM DR-118 16Kx12 core memory for PDP-8/e. I have the documentation on the DR-118A which is for the PDP-8/a. It is probably similar, but would love to find the right version. Anyone have such thing? Thanks Eugene

Sun E10000 Historical Enquiry

by jplist2008＠kiwigeek.com

Greetings to all; All this talk of favourite machines and getting into the hobby has gotten me amped up to work on my E10k. The E10k was always the "coolest" machine for me - largely due to the timing of my entry into the industry. I recently read Tracy Kidder's Soul of a New Machine and was pondering the history of the E10k and its start in Cray Research Inc and its subsequent sale to Sun. The asset transfer that must've taken place and then how Sun turned it around to make it a Sun product and made its impact on the market has to be a fascinating story too. I would love to talk to anyone who was involved in the development, transfer, initial rollout and support of the E10k - from both CRI's and Sun's perspective. Heck, I'd be fascinated to talk to anyone who purchased the machines during their lifespan (1997-2001) and could tell me what you used them for. If you only know of someone that was involved that you might think would be interested in talking to me, please pass my eMail address on. Maybe if I get a big response I could put something together, if there was suitable interest of course. But at this point, I'm mostly just fascinated for myself. Thanks to all! - JP
