In regard to the Freeware CDs for RSX-11 and RT-11
that Tim Shoppa originally produced:
I am in the middle of making up a second (very small) batch
of CDs and could easily add a few additional copies.
I will be making all copies of the CD images from:
ftp://ftp.trailing-edge.com/pub/cd-images/http://www.classiccmp.org/PDP-11/RT-11/http://www.classiccmp.org/PDP-11/RSX-11/
Since not everyone has both a high speed internet connection
and a CD burner, I thought it would be helpful to make them
available. If you have both requirements and are using
Windows 98 SE / Nero Burning, I can help with the details
if you don't know how to burn a CD from an "Image File".
I have even been able to produce a label for each
CD that is close to the original label from Tim Shoppa,
although since they were scanned (THANK YOU
FOR THE HELP), they are not perfect.
They are available at $ 5 / $ 9 / $ 12 for 1 / 2 / 3 CDs.
In addition, I understand that Memorex Black CD-Rs have a
longer shelf life and are available at Business Depot. If anyone
wants those instead, add $ 1 for each CD that you are
requesting. Thus those amounts are $ 6 / $ 11 / $ 15
I will be picking up some Memorx CD-R blanks in a few days
and starting on the copies for those who have already requested
that a Black CD-R be used.
Please include your mailing address!!!!!!!!!!!!!!!!!!!
In general, I will regard any funds you send as a gift so that if
anyone really can't afford the CDs, please state why that is so.
Outside of the US, probably about $ 2 should be sufficient
for extra postage. All amounts are in US dollars. Please ask
if you are not in the US. No point in converting twice.
Sincerely yours,
Jerome Fine

They all are Intel AboveBoards.
Intel made aboveboards that took 256K DIPs, 1 Meg DIPs and 30 pin SIMMs. They
made 8 bit versions beside 16 bit versions. With the DIP Daughter board IIRC
you could get 16 Meg of RAM on the card. Some of the 16 bit versions could be
used in 8 bit slots. It was a very versatile line of cards for many years.
An interesting side story. They came out with a 5 year warranty. Intel in
Hillsboro, OR used to have employee sales where Intel employees could buy
surplus and scrap at bargain basement prices. Several people bought some non
working aboveboards that were failures from the production line. They then
got turned in for warranty repair because they were less than 5 years old.
Once Intel figured out what was going on that was the end of the employee
garage sales. From that point on they shredded the production failures in
Hillsboro.

I saw that one go by and it seemed like a good deal. But I've got a couple
FuturePlus FS2230 SCSI probes to go along with the logic analyzers I have so
I had to resist the urge to buy more hardware.

Yes, these are AboveBoards. The one I had had DIP RAM chips. The ones with
SIMMs must be more recent.

Humm... then maybe what I have isn't "AboveBoard"'s.
I'm pretty sure the ones I have don't have SIMM slots. I think they are
just a whole mess of DIP chips sitting in sockets right on the board.

I'm pretty sure the ones I have don't have SIMM slots. I think they are
just a whole mess of DIP chips sitting in sockets right on the board. I
think some of them are even multiple layers deep (a daughter card
attached to the main card to add more chips).
I thought they were labeled "INTEL AboveBoard", but maybe I'm mistaken
and they are some other memory upgrade board. I do know they are RAM
upgrades and they are for ISA slots... that much I am sure about.
Although I do (or did?), have one with SIMM slots for an MCA bus for
PS/2's. I think I sent that to Larry when I sent him a bunch of 486
parts, but I'm not sure (like most of the rest of you, I just have piles
of stuff... and I'm not always that good at keeping track of it)

I think I might have a box of Intel AboveBoard's. I'm not sure how many,
or how much ram is on each, but I seem to recall that I have a file box
full of them tucked away under my parts shelves somewhere.

It cost a few bucks to get, but I know what these beasties can do...
What beastie? Oh, sorry... an Ancot DCS-216FT standalone SCSI bus analyzer, in pretty darn good shape. Snagged it from Ebay for $250. Considering that I've rarely seen them going for less than a grand, I think I got a decent enough deal.
One of the tech support guys at Ancot was kind enough to send me the user's manual. Now, if I can just get a differential adapter as well...
Heck, maybe I can build one... we'll see.

Ethan,
There is a lot added (it's about half as thick again as the first edition).
I seem to remember there was a little stuff taken out, but I sold the first
edition years ago now and can't remember what it was - it certainly wasn't
anything that I miss. I'd recommend "upgrading" as there is quite a bit of
practical stuff which is very useful in the second edition.
The lists of op-amps and suchlike is a bit outdated now though, so it'd be
nice to have a third edition!

Subject: "The Art of Electronics" - edition differences?
To those that have "The Art of Electronics", is there much difference
between the first and second editions? Is one "preferable" to the
other for those of us with Classic interests? Did they take anything
we would find useful out in the editing process?

I have learned that to ignore the facts

Just a quick note to point out the article by Christine Finn in
today's Guardian newspaper:
http://www.guardian.co.uk/g2/story/0,3604,906984,00.html
It's on page 7, in the G2 section, if you have the paper version.
