Qbus & Unibus cards avalable, DRV-11 & RX01 & RX02 disk controllers & more

by Innfogra＠aol.com

Hi; I have posted the rest of the cards, that listmembers did not speak for under my eBay user name Innfosale. Most are cheap, starting at $4.00 Here is a URL: http://cgi6.ebay.com/aw-cgi/eBayISAPI.dll?MfcISAPICommand=ViewListedItems& userid=Innfosale&include=0&since=-1&sort=3&rows=50 I will ship internationally. The Global Priority envelope is $10 and will hold a dual width card. Air Mail is a little cheaper for several cards. Paxton Astoria, OR

Is HSC90 a PDP-11 or what?

by gunther＠aurora.regenstrief.org

Who knows what processor/architecture an HSC90 is? Is it a PDP-11? What's it's bus? Sounds like it doesn't mix with UNIBUS or Q-BUS cards at least not looking at the card numbers "Lxxxx" (HSC) vs. "Mxxxx" (UNIBUS/Q-BUS). The reason I'm asking is that I'm looking for the most multi- use of my big-iron hardware that takes up so much space. I believe I will be able to run the console computer of my future 11/78x as a PDP-11. Would be nice if this is possible with the HSC90 as well. I would like to: - provide a PDP-11/RSX-11 environment for my neighbor to play with without getting a dedicated PDP-11. Probably I can do that in the future with the LSI-11 of the VAX 11/78x that hopefully some day will decorate my garage. - try running 2.9 BSD on a PDP-11. Not knowing much about 2.x BSD, I could imagine making the HSC90 into a UNIX-based file server or something. regards, -Gunther -- Gunther Schadow, M.D., Ph.D. gschadow(a)regenstrief.org Medical Information Scientist Regenstrief Institute for Health Care Adjunct Assistant Professor Indiana University School of Medicine tel:1(317)630-7960 http://aurora.regenstrief.org

Want to be the subject of Christine Finn's next book?

by vcf＠vintage.org

Christine Finn, author of _Artifacts: An Archaeologist's Year in Silicon Valley_ (available for sale on Amazon, more information at http://www.artifactsthebook.com/) is starting on a new book that will cover how people use technology in the United States. She would like to profile/interview a collector in every state of the union, including Alaska and Hawaii. Christine says: "I am about to start on a follow up to 'Artifacts: an archaeologists's year in Silicon Valley'. It will also be published by MIT Press, and take a broader look at technology in America. Central to research will be travelling to as many parts of the US as I can - Hawaii and Alaska included - over the next year. However, I do have very limited resources and would be really grateful if any collectors or classic computer enthusiasts could offer me an overnight stay and/or a place for me to get online. More than that, it would give me the chance to meet more of you, and find out about how you feel about technology in its various forms. I can offer a copy of the book and an Artifacts reading/discussion in your locale, if you'd like to arrange it. "If you can help, do please get in touch with me christine.finn(a)arch.ox.ac.uk". If you would like to be considered, please respond directly to Christine at <christine.finn(a)arch.ox.ac.uk>.

Datapoint 1100, 2200 and 5500 processors

by spedraja＠ono.com

Hello. I recently received one book named "A guide for operating Datapoint Equipment". It is 88 pages long and describes very good all the processors and peripherals that could be attached to one of these systems. In another place in the Internet mentions that the cassette operating system of these machines was the CTOS (yes, the processor appeared to have a couple of cassette units and load the OS from one of it). Do somebody has software for this machine ? Is it possible to get something for one repository or download place ? Do it exists some documentation scanned or available ? I should like to know experiences of everyone with this machine if this can be possible. And finally... Somebody knows a place where one of these systems would be working or at least operative ? Thanks and Greetings SP

70's Mattel Handheld Football game...

by bpope＠wordstock.com

All, Someone was asking about this awhile ago. Target is now (re)selling the 1970s "Handheld Electronic Classic Football Game" for $12.99 At: http://www.target.com/common/catalog/product.jhtml?prodid=83988&navAction=j… If you also go to http://tomheroes.com/retrotimes_51.htm#New%20(Old)%20Handhelds%20(Are%20Bac… there is info about other handhelds being rereleased. Now speaking of handhelds, does anyone remember playing the handheld pinball game? I can't think of the name of it right now... Cheers, Bryan Pope

Dead Intel MDS controller board

by dmabry＠mich.com

Well, much to my dismay, but not too surprising, my last set of floppy diskette controller boards has failed and my Intel MDS is severely crippled. In my days of designing systems with Intel Microcomputer Development Systems I saw many of the floppy controller boards fail. That system had a two-board set of multibus cards in order to control up to four floppy diskettes. Seems kind of funny to call those huge 8" floppys "diskettes", but that's what they are. Anyway, of that two board set, I always have seen the same one fail. One card called the Channel Card which was based on Intel's 3000 series bipolar microprocessor never failed. It was always the other card, the Double Density Interface Board. When I "retired" all the MDSs where I worked, I kept three sets of those boards to keep my MDS going, fully expecting to have one or maybe even two go "bits up". Alas, last week, my third and last board set failed. And, yes, it was the interface card. The purpose of this post is to see if there might be someone on this list who would be able to advise me on a strategy for troubleshooting it (Tony Duell?) Better yet, but I'm not going to hold my breath on this one, would be someone who has an SBC-202 board-set he might be willing to part with, sell, trade, etc. Any ideas or leads would be appreciated. And, Tony, I might have a space ICE-80 manual for you. Will know next week. Thanks. Dave -- Dave Mabry dmabry(a)mich.com Dossin Museum Underwater Research Team NACD #2093

old 8080 micro system available

by frustum＠pacbell.net

I'm forwarding this information from a fellow who sent me an email asking if I was interested in his computer. I'm not, but I told him I'd forward his contact information. Please reply to him for requests about more information. Based on his area code, it looks like he is in or near Houston, TX.

The original maker was an engineer from Warner Swayze Corp., Cleveland Ohio, Abe Zeewe. The operation system was ISIS, the programming language was a pseudo-fortran.

I don't know if it still works. This machine was a prototype developed for Realistic Control Corp. of Cleveland. I developed the software. The translator and the operating system are still on the machine. The last time it ran was around 1980. There are many items inside that are hand wired. To permit additional air flow, the engineer cut an "X" in the front of the case, which was covered by 4 layers of gauze bandage acting as the filter. I am asking for an amount commensurate with the historical value plus shipping. I am also including the Centronic model 700 RO printer (serial # 086) and an Ann Arbor terminal. I may also have wiring schematics available. Side note: I remember personally running jumpers from various pins on the processor to make the machine work. ---- end of 2nd email ---- ----- Jim Battle == frustum(a)pacbell.net
