Listing of 60s mainframes/minis with CRT displays?

by dmonnens＠gmail.com

Thank you to everyone who has responded so far. Let me clarify a little - Marty and I are looking for a list of computers >from about 1971 and earlier (1977 at the latest, but the real focus is on the 1960s) that had the capability of playing Spacewar. We've had reports of a few different machines running it, but obviously there are going to be a lot of gaps in oral history. Having a list of machines with displays (CRT, vector, or other) would help identify where some of those gaps might be. Here are all the machines we've had reports of Spacewar on them: 1. PDP-1 2. PDP-4 3. PDP-6 4. PDP-7 5. PDP-8 (probably text-based version) 6. PDP-10 7. PDP-11 8. LINC-8 9. DEC-10 10. HP59825 desktop calculator 11. 544 ARTW/Trajectory Division 12. PLATO 13. DDP-224 14. IBM System/360 (IBM 2250 Model 1 display) or 2250-4 (a 2250/1130 Model 4) 15. CDC-3100 16. Data General NOVA 17. IMLAC PDS-1 18. Virtual Machine Facility/370 (VM/370) Note some of these have multiple versions created in different locations independently. 1972 is a key date because that's when PLATO went on the ARPANET, and software could be more widely distributed. This was also the first year that Spacewar was written for a home computer in BYTE Magazine. 1977 was the release of the arcade version and publication of a version for the Altair 8080. Want to clarify that we're not looking for home computer releases, unless maybe you have examples earlier than 1977. > On Mon, May 26, 2014 at 05:08:41PM +0100, Dave wrote: > > > > If you are talking 1960's I think the real answer is "not much".

7, 500 Amiga Pirated Amiga Warez Disks & Demos- Need to find someone to archive them and find them a home

by slandon110＠gmail.com

Guys I bought an Amiga with over 7,500 Pirated Amiga Warez Disks And Demos, you name it its on these disks. Just looking to sell them cheap to someone outright who will archive them and post them online for everyone. Like 250 dollars for the entire lot cheap. And they will ship media mail even cheaper

A small collection of PDP8's and PDP11's in Adelaide

by bob.willson＠adelaide.edu.au

Hi All, I have a small collection of PDP8's and PDP11's in Adelaide South Australia. The group is made up of a PDP 8/L, 2 X PDP 8/E's, 2 X PDP 8/F's, a PDP 11/10, a PDP 11/20, and a PDP 11/44. The 8/L is bare but the rest have RK05's except the 11/44 and an 8/F with floppies. Their purchase was arranged by me in the 1970's and they have been given to me by the School of Psychology at the University of Adelaide. They have been stored in an air conditioned environment since purchase. A couple of years ago when I began to think about disposing of this equipment my ambitions were quite small and I thought I would just put them up on ebay and see what happened. Since then I have looked at the computers more closely and with the assistance of the former engineer involved at the time we have put 3 of the computers back in operation. As far was we can tell the PDP 8/L runs trivial programs, the PDP 8/F with floppies runs OS/8, and one of the PDP 8/E's runs the processor OK but the Plessey disk (RK05 look alike) didn't boot (but we'll fix that). Currently the former engineer is a lecturer in Computer Science and has expressed an interest in one of the PDP8's in a running state as an exhibit in his office. I may keep the 11/44 but we need to dispose of the rest, eventually, and in a running state. We think we will put up the 8/L for sale first. The package consists of the 4K PDP 8/L, a BA08 Expansion Box containing a KV8/L controller, a Tektronix 611 display and a 1250VA DEC Autotransformer to run the 115V 8/L system in the 230V land of Australia, and associated documentation. The PDP 8/L powers up and the fans and power supplies check out. Memory addresses can be examined by auto incrementing through memory. Data can be deposited in memory. Trivial programs seem to execute and switches seem to perform their intended function (allowing for a little intermittent functioning after 30 years stasis). I believe both the PDP 8/L and the KV8/L controller can be functioning systems. I know there is an international market for this equipment but is there anyone or any group in this country (Australia) that we might give advance notice of an intention to sell this sort computing equipment? Let me know if you are interested or want further information (bob.willson at adelaide.edu.au).

Basic Four 410 / Microdata 1600

by ad＠ardiehl.de

Hi, i recently got a MAI Basic Four 210 from the Netherlands. The CPU now powers up, have not yet tried the 14" Piram harddisk. I would like to know if the CPU is working. It seems to be based on a microdata 1600 but equiped with dram and cmos ROMs. The machine has switches were it can be set to boot standard/alternate >from disk, tape or from a serial terminal. Since the tape drive has a capstan roller transformed to liquid and i have not yet tested the disk i would like to know how to boot from a terminal. I have not yet read the microcode proms nor have i checked if they are soldered or on sockets. Does someone out there have access to the cpu manuals that are stated in the service manual ? 1300 CPU Technical Manual, Document No. SM 1200 M1300 Series CPU Organisation and Description Reference Manual Pictures from the machine are here: http://www.ardiehl.de/basicfour/mai210/pics/small/ and the manuals are on bitsavers in pdf/mai, the service manual also contains the cpu schematics, the ones for the tape controller and the disk controller are included in the tape / disk service manuals. What do you think are the chances to get the disk up and running. (since i have no tapes of other software) All seems to be stored dry, no rust, nor a lot of dirt in the machine. Seemd to be powered on the last time more than 15 years ago. ---------------- Gr?sse Armin Diehl ad at ardiehl.de

How to create a CF boot DOS

by ckblackm＠yahoo.com

I don't know if the way I did it on my 486 box would work on a 286, but I simply looked up the spec's to my compact flash device on google and simply treated it like a hard drive.? I then installed MS DOS via floppy disks onto the CF card pretending it's a hard drive. HTH, Christopher.

Listing of 60s mainframes/minis with CRT displays?

by wgungfu＠gmail.com

Hey guys, we're on the next phase of our paper we're presenting at a conference soon and are hoping to collect a listing of 1960s era mainframes and minis that had CRT displays available for them. We're obviously already aware of the various DEC models released in the 60s that had them, but we're looking for other brands now. If you guys would be so kind to help us out (since we're in a bit of a time crunch) and share the following, it would be awesome! Computer maker and model: CRT maker: Dot, vector, or character display: Thanks! -- Marty
