There is no written documentation I have ever come across that there was ever anything called an Alto III. The only follow on to the Alto II was the Alto II XM, which added bank switched memory and a larger writable control store. Alto II was a redesign of some of the Alto I for manufacturability done in El Segundo. Chuck Thacker did the "Dolphin", which was the first Xerox OIS workstation. The 8010 is an adaptation of a paper design that Butler Lampson did called "Wildflower" The next machine Chuck worked on after the Dolphin was the Dorado.

Classic computer ads from the October 1976 issue of "Popular Electronics"

by joachim.thiemann＠gmail.com

Hello, while doing some cleanup, I came across the October 1976 issue of "Popular Electronics". Finding some fun ads for classic computers I decided to scan them for the benefits of owners of those on this list :-) IMSAI 8080 full page color ad Altair 680 full page color ad Poly 88 3/4 page b/w ad Schweber SC/MP 3/4 b/w ad SWTP 6800 full page b/w ad Processor Technology single column ad for an I/O card I've put them up on picasa for now, but those are low quality jpg images - if someone wants the full 600dpi lossless scans (huge!) please e-mail me. Note, I'm not quite sure about the copyright issues involved in scanning ads for defunct companies out of defunct magazines. If someone here tells me ther is an issue, I'll remove them ASAP. http://picasaweb.google.com/Joachim.Thiemann/ComputerAds Enjoy! Joe

SGI Crimson

by fire＠dls.net

I appear to have misplaced, or accidentally given away my SGI Crimson keyboard and mouse. Also, I have a dial box, with AC adapter, and data cable but cannot recall how to hook it into Crimson. Seems to have the same proprietary mini-din that Crimson Keyboard and Mouse use. Does anyone want to part with for cash, or trade? I could also borrow them for a few days if someone is in Chicago area. I just have a few things I have to get off machine. I am seriously considering taking Crimson out of my collection, so interested parties, especially interested parties with keyboard and mouse should email me. Bradley

Olson 8080 S-100 info?

by legalize＠xmission.com

Hi, A coworker has this old S-100 based machine (date codes indicate 1977 or 1978) for which he has no docs: The cabinet has "Olson" on the front and the label on the back gives the part number as NP-210. The CPU card is a BYTE MPU C1000-1001. There is a serial/parallel card: Solid State Music IO-4. All the chips have been removed from the sockets on this card :-(. There are also 3 cards of memory on the machine, mostly fully populated. There is a nice set of lights and toggle switches on the front panel. The front panel card connects directly to the bus and has a ribbon cable that connects to the CPU card. (Was it common on S-100 bus based systems to have a front panel that was a card attached to the bus?) My guess is that there's a boot PROM on the front panel card (there are two PROM sockets on the CPU card that are empty) and that this is debouncing the toggle switches and whatnot and controlling the LEDs. I told him I'd ask around for information on the boot PROM and the cards in his system. Can any of you S-100 fans help me out here? -- "The Direct3D Graphics Pipeline" -- DirectX 9 draft available for download <http://www.xmission.com/~legalize/book/download/index.html> Legalize Adulthood! <http://blogs.xmission.com/legalize/>

String Logic

by marvin＠rain.org

I was listing some books on VCM, and ran across a mechanical EXCLUSIVE OR demonstration photo using string. I had never seen or heard of such a thing before and thought it was very cool! The book is Computer Hardware Theory, and a jpg of the string XOR picture is at: http://www.rain.org/~marvin/strngxor.jpg

If its docs or software, I don't bid against Al Kossow knowing I'll reap the benefits later anyway :) --------------------- Likewise. But I also ask Al when something comes up and he isn't bidding, in case he missed it. Usually, it means he didn't bid because he already has it. I try to buy what I can and give it to him for the archives. That helps lower his expenses. Finally, I never sell any documents or tapes until Al has a chance to add them to his archives. He has first dibs on anything in my collection. When someone is doing so much to benefit the entire hobby, they should be supported in any way possible. Billy

Fwd: [comp.sys.dec] Selling my PDP-11/83 and various spares..

Id: <45d4fdf3$0$16270$88260bb3 at free.teranews.com> ======== All, I have to move house and unfortunately the new place doesn't have enough room f or my PDP-11/83 and all my other junk. Over the next week or so I will be putting up whatever I I think might sell on eBay. You can see the current list at: http://search.ebay.com.au/_W0QQsassZtesneddonQQhtZ-1 Hopefully that URL will work for everyone else :-) I have split up the system into parts as I can't imagine too many people would want to ship the entire machine, anywhere. There are also some spares and as I disassem ble my MicroVAX 3400 and VAX 4000/200 more Q-BUS parts will become available. Once again I'm only selling this equipment because I don't have a choice. I wou ld like to give it away, but I am also getting married soon and every little bit helps. Hopefully this gear will find it's way to a good home. Regards, Tim. PS. Apologies for the cross posting. -- Posted via a free Usenet account from http://www.teranews.com

SWTPc 6800 vs. Altair 680

by billdeg＠degnanco.net

Are the programs from the SWTPc 6800 interchangeable with the Altair 680? Is there a good web reference that compares these two?

I'm in San Antonio, and I'll have an opportunity to do that on Wednesday, 21-Feb. Email if you are interested in having me do so. I know nothing about HP 1000 machines, so I'll need lots of "look-for-this" type information if I'm to be of much use. -- Mark, 210-379-4635 --------- >you don't have to control EVERYTHING. you can let things happen >and then merge the streams. there is elegance in simplicity. - Arthur Leung, 2006
