Looking for just the chip or a board level product?
Why are you looking for one and how much are they going for these days?

oops a mind melt. 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.

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...

The future was never like this!
Does anyone have information about a Datapoint 1550 ?
And perhaps a picture of one ?
Thanks,
Stefan.

Intel offers $10,000 for Moore's Law article
Firm seeks pristine copy of founder's prescient words
Intel Corp. lives by Moore's Law, but it apparently doesn't have a copy of
the magazine in which the law was first laid down. 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

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.

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 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.
