DEC PDP-8/E wanted

by ccth6600＠gmail.com

I know it is the year 2020 but nevertheless what are my chances of finding a complete and repairable DEC PDP-8/E or as a second choice a PDP-8/I ? Is there any hope or should I be just content with my SIMH based PiDP-8/I? Thanks Tom Hunter

LCD screen repair

by trash80＠internode.on.net

Hi folks - be grateful for a little advice please. Some time I rescued an Apple Power Mac G4 (it's a beautiful machine, not that I'm a big Mac person, and I can't believe someone was going to toss it) - powers up OK but looks like it just needs a new battery as its not holding date and time. Anyway the other day I was cleaning up in my collection facility and dropped the monitor - I wasn't quick enough to save it from hitting a metal object just under the bench and as chance would have it of course this happened screen side. Its put a gouge in the surface of the screen - link to photos below. http://koken.advancedimaging.com.au/index.php?/albums/apple-screen/ Now I believe it is possibly repairable but the are many kits and methods out the all claiming some success. I figure I'm only going to get one shot at this so would appreciate any advice from anyone who may have effected such a repair before. Thank you. Kevin Parker <https://t.sidekickopen76.com/s1t/o/5/f18dQhb0S7n28cFFdQW752kH81jkhdLW1_k-L- 1qZM43W3s0v_y2M0f8BF4c2NfHml5Hf6Bq4h603?si=8000000004908274&pi=2139d449-dcd9 -4daf-91a4-c2defc817fd5>

FS: Tek scope, HP LA, and Electronic components!

by mechanic_2＠charter.net

Hello all, I have probably developed cancer. I can't get in for treatment. I have enough lumps in my body that it probably wouldn't make a difference. So more than likely I am dying. I am asking for everyone's help. I am selling off all of my processions and simplifying my life before I die. I don't want to see this stuff end up in the landfill. Please help out a dying old man? I have a Tektronix 465B Scope with four probes for sale. A HP 16700A LA with 5 16555D LA cards and all of the cables. There is a 16701B Expansion box and the interconnect cable. There is an external SCSI drive box with a CD rom and a ST318417N drive in it. There are a bunch of micro probes for the LA. A monitor, keyboard, mouse, manuals, and CDs. I also have a very large collection of electronic components in over 40 storage cabinets. There are also a lot of books on electronics. I am asking $250 plus the shipping on the scope. This shipping won't be cheap. $500 plus shipping for the LA. Again shipping will be very expensive. It will take five boxes to ship the LA. I will deliver the scope and/or LA to any where in the lower 48 for the cost of shipping. $500 for the components, cabinets, and books. Shipping is not possible. So it it have to be local pick up. Bring a truck and trailer. PP F&F, Cashiers Check, or Postal Money Order. Please contact me off list. GOD Bless and Thanks, rich! Happy Thanksgiving!

DEC PDP-8/E wanted

Hi Chris, There's a few options in this regard, in increasing degrees of "realness" (and cost!) depending on how you define it. 1) The PiDP-8 by Oscar Vermeulen - Raspberry Pi based 8/i replica running SIMH in a miniaturised case. https://obsolescence.wixsite.com/obsolescence/pidp-8 2) The SBC6120 - Originally by Spare Time Gizmos, but now re-released by the RetroBrew Computers community. This is a 6120 based PDP-8/e replica, with optional front panel. (the panel doesn't appear to be made "officially" anymore, as the design files are missing, but a Russian company appears to have copied it. (I have the Russian version but have yet to assemble it.) https://www.retrobrewcomputers.org/doku.php?id=boards:sbc:sbc6120-rbc-editi… http://www.sparetimegizmos.com/Hardware/SBC6120-2.htm https://chipkin.ru/product/pechatnye-platy-dec-pdp-8-e/ 3) The LD12 / LD20 by Franklin Prosser and David E. Winkel - This is a TTL based clone of a PDP-8/i, originally devised as part of an exercise in the book "The Art of Digital Design An Introduction to Top Down Design" in the early 80s. A few people on vcfed.org have built their own based on these designs, and daver2 has made a run of PCBs (wirewrapped!) http://www.vcfed.org/forum/showthread.php?74125 4) Vince Slyngstad of so-much-stuff.com has scanned many PDP-8 boards and re-created them in Eagle CAD software. I know he's been working on re-creating the 8/e CPU recently but AFAIK it's not finished yet. There are however many OMNIBUS peripheral cards, and a board that combines 32KW of battery backed RAM with a boot ROM. Roland Huisman has also re-created the RX8E floppy controller, and has made an RX02 emulator to go with it, so if you lack an RX01/2 drive you can still have something to boot off. Kyle Owen has also created a neat bit of software that allows you to use a spare serial port and a *NIX system to simulate an RK05. So with all this, it should in theory be possible to build your own 8/e class system soon enough if you can find all the parts for it. http://so-much-stuff.com/pdp8/cad/boards.php https://github.com/Roland-Huisman https://github.com/drovak/os8diskserver Regards, -Tom mosst at sdf.org SDF Public Access UNIX System - https://sdf.org
