Navtel 9460 Protocol Analyzer info?

I confused a rather decrepit ARI data monitor thats likely beyond hope (dropped from height) with the one I need schematics on. The one I'm looking for data about is a T-bar Explorer pn5915-10 with a 9/1982 date. The control logic inside is three STD bus cards. It's 5.25"hx8.5"wx15"D. It has no data storage tape or floppy.

Unix on old-ish machines - advice sought

by stanb＠dial.pipex.com

Hi, I'd like to get a straight (ie no X) Unix running on some sort of older, but not necessarily ancient, hardware. My Micro-11/73 is not really suitable, and PDP-11s that are seem to be a bit thin on the ground over here in the UK. I've seen a few Vaxen and MicroVaxen on the market lately so my thoughts are turning in that direction. I know a few people here run such machines and I'm seeking advice on the best machine to look for and, at the risk of starting a religious war, the best unix to run on it... :-) TIA... -- Cheers, Stan Barr stanb at dial.pipex.com The future was never like this!

Intel offers $10, 000 for Moore's Law article Firm seeks pristine copy of founde

The Santa Clara chip giant has posted a $10,000 bounty on eBay for someone who can provide a pristine April 19, 1965, copy of Electronics magazine. That issue of the magazine contained an article by Intel co-founder Gordon Moore that described how the number of components on integrated circuits was doubling every year. The article became the foundation for his famed dictum. "We have photocopies of the article but not the actual issue of the magazine," an Intel spokesman said. "Gordon doesn't have it and the Intel Museum doesn't either." Electronics magazine went out of business several years ago. Intel turned to the online auction site on Monday, posting a message on eBay's Want It Now page offering $10,000 for a copy of the magazine in mint condition. (The company may buy more than one copy but at a lower price. Intel employees and their families are ineligible.) Moore's Law -- which has since been revised to estimate that the number of transistors doubles every 18 months -- has been the cornerstone for the information technology industry for decades as it has defined how products can simultaneously drop in price while improving in performance. This has created a situation in which users upgrade well before their equipment breaks, a boon for the industry. Despite its historical significance, the article at the time wasn't considered a monument. "I didn't think it would be especially accurate," Moore said in a recent interview. Moore, 76, was born in San Francisco and received a bachelor's degree in chemistry from UC Berkeley. He was research director at the Fairchild Semiconductor division of Fairchild Camera and Instrument Corp. when he wrote the Electronics magazine article in 1965, and in 1968 he co-founded Intel. Chronicle staff contributed to this report. Page D - 1 URL: http://sfgate.com/cgi-bin/article.cgi?file=/chronicle/archive/2005/04/12/BU…

ASCII art spam

Si le dictionnaire ne >contient pas la langue dans laquelle le courriel est ecrit.... You people REALLY need to start paying attention to emoticons and learn to read the sarcasm between the lines. :-p The point was a joke. Collateral damage causing loss of email with spelling errors was supposed to be a good thing. Following the same JOKE logic, loss of any email that I can't understand (including other languages, mathematical formulas, or most everything Tony Duell talks about since it all goes way over my head), may also be good thing. ;-) Besides have you interacted with anyone under 18 via email recently? Maybe filtering on spelling errors IS a good thing! =:-O :-) (watch out for those emoticons, they are the only way in email to point out jokes and sarcasm). -ps: this email was spell checked by Claris Emailer 2.0v3 that doesn't know "email", "spam", "emoticons", "Duell", "ps", and "2.0v3" are all acceptable. -chris <http://www.mythtech.net>

Texas Instruments TMS2600

by marvin＠rain.org

I took a look in a 1977 IC Master and they show the TMS2600 as discontinued. However they show alternate sources as an AMI S8773 and National MM4230 and MM5230. BUT, the First Edition of "The Integrated Circuits Catalog for Design Engineers" from TI has the TI datasheet and specs starting at page 14-139. Pinout: 1 - A3 13 - A9 2 - A2 14 - CS 3 - A1 15 - MC 4 - B1 16 - Vgg 5 - B2 17 - A8 6 - B3 18 - A7 7 - B4 19 - A6 8 - B5 20 - A5 9 - B6 21 - A4 10 - B7 22 - NC 11 - B8 23 - NC 12 - Vss 24 - Vdd A - input B - output MC - Mode Control CS - Chip Select Vdd - drain power supply Vgg - Ground power supply Vss - Substrate Supply voltage Vdd - -12V nominal Supply voltage Vgg - -24V nominal Input chip select logic 1 - -12V nominal Input chip select logic 0 - 0V nominal input pulse width - 650 ns minimum "A logical 0 on the chip select input will cause the outputs to become open circuits on the "single-ended" (open drain) type output buffer and will cause the outputs to go to Vdd on the double-ended (push-pull) type output buffer. > I've recently acquired an old Wang 144T programmable electronic calculator. > Early '70's technology.

For The PDP-8 Folks

by djg＠drs-c4i.com

>> AX08... the closeup looks like Negibus notation. Can't tell much more >> than that from the limited pictures. > > >I've been curious about the AX08; maybe someone will buy it and scan it. >The price is down in the impulse buy range, so there is hope for the auction >:-). > I have a bid in and I will be scanning it and putting it on my site if I win. Since I have an AX08 with a fault in it I would really like to win it. I had gotten a copy of the manual which is on my site but the schematics were copied folded so were unuseable. I was unable to get a good copy of them. I got the point plot working but not the A/D. Thanks, David Gesswein http://www.pdp8.net/ -- Run an old computer with blinkenlights. Have any PDP-8 stuff you're willing to part with?
