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.

4M expanded memory cards

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. Paxton Astoria, OR

Holy cow, what a find...

by glenslick＠hotmail.com

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. > What beastie?

4M expanded memory cards

by Robert_Feldman＠jdedwards.com

Yes, these are AboveBoards. The one I had had DIP RAM chips. The ones with SIMMs must be more recent. -----Original Message----- From: chris [mailto:cb@mythtech.net] Sent: Thursday, March 20, 2003 2:23 PM To: Classic Computer Subject: Re: 4M expanded memory cards > Yep, I've got an Intel ISA AboveBoards too. 8 30 pin SIMM slots. >Currently is loaded with 1MB SIMMs. Anybody want it? 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. <snip>

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) -chris <http://www.mythtech.net>

>I remeber some brand of memory addon cards were prised back in the 286 era, >Intel Aboveboard comes to mind. 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. -chris <http://www.mythtech.net>

by kyrrin＠bluefeathertech.com

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. 73 de KC7GR -=-=-=-=-=-=-=-=-=-=-=-=-=-=- Bruce Lane, Owner & Head Hardware Heavy, Blue Feather Technologies -- http://www.bluefeathertech.com ARS KC7GR (Formerly WD6EOS) since 12-77 -- kyrrin(a)bluefeathertech.com "I'll get a life when someone demonstrates that it would be superior to what I have now..."

"The Art of Electronics" - edition differences?

by Paul.Hills＠siemens.co.uk

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! -----Original Message----- From: Ethan Dicks [mailto:erd_6502@yahoo.com] Sent: 20 March 2003 15:47 To: cctalk(a)classiccmp.org 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? -ethan

Article on computer collecting in today's Guardian (IUK)

by coredump＠gifford.co.uk

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. Big photo of Sellam's collection, and one of Sellam himself. Small mention of my collection, too. -- John Honniball coredump(a)gifford.co.uk
