They show a SIM-8. The entire setup is similar to my SIM-4 except that the CPU board is wider. Dwight

Selling medium old software

by dwight.elvey＠amd.com

Hi I just saw article # 23439 on the inquirer about a fellow that has a collection of "old" software. On checking the article a little more, I find that "many of which are for non IBM PC machines". Wow! Some for such RARE machines as Commodore 64 and Apple II. He expects to auction it off starting at $199,000 It seems to be truck loads though. His pricing does seem a little high. My heart flutters with excitement. Dwight

FYI back in that time frame Signetics, Intel and Fairchild had a DTL/TTL product in the 3xxx class numbering. For example: 3205 similar to 74138 may be differnt pinout 3009 similar to 7432 9602 onshot similar to 74123 however the 9602 was truly a better part. 3404 8bit wide latch maybe similar to 74100 or 74373 1101 256x1 Pmos (two voltages) and really slow (1.5us parts were the fast ones) There were others but those appear on my drawing and those of the MCS-8. The greatest part of that era, 2102 1kx1 1us (initial pricing $16 ea). Allison

Better indexing on bitsavers

by aek＠bitsavers.org

On a separate post I mentioned cross support/cross linking. It was my clumsy way of saying indexing. I would be nice if people pitched in and just did it. I may make a list of all of the chips listed in the individual PDF's that Al has posted for the westerndigital datasheets. If Al then posts this index with the PDF's (or creates an index folder) so the googlebot can scan it then a google search would point you where to get it. Simple with the task easily shared amoung many people. -- That would be a wonderful thing. I have a HUGE backlog of scanned databook material, and just finished picking up almost 40 book boxes of 70's -> 90's data books from a third large collection. The first was from the databook collection of Haltek Electronics (RIP), the second from a private collection that was given to us with the promise that it would be scanned, and now this addional one. (I've found a few interesting things in the last lot already.. A copy of the Fairchild '69 data book, a book by Gnostic Concepts on early 70's memory technology, and two of the classic error correcting codes books) There is no way I'm going to have time to OCR or index this. A simple text file per PDF with part number and page number would be wonderful. This is also the sort of data that Google seems to index REALLY well. Watching the hits on bitsavers, almost everyone finds the archive by stumbling upon the 'whatsnew.txt' or 'Index.txt' files. I'd be interested in suggestions for what books should be higher on the post-processing queue too. I probably have 50 databooks scanned but not PDFed right now. I've been concentrating mostly on getting the classic early stuff done first (2nd Edition TI TTL Data Book, etc.)

Dayton aquisition - Socket-brand S-I/O PCMCIA card question

by ethan.dicks＠gmail.com

What could be one of my more interesting scores is a Socket-brand (www.socketcom.com) S-I/O PCMCIA serial card for $2. Natually for that price, it has no dongle. Dongles for modern Socket products (they make CF serial as well as 3.3V PCMCIA serial) are available new, but I was curious if anyone here has ever worked with these cards and might know if the dongles might be the same? The places selling the dongles list the compatible card part numbers, but this card does not visually match their current offerings, and it's not obvious what the model number is, except perhaps "S-I/O". The numbers below the compatibility glyphs on the back are "8010-00012 L" (which _might_ be a part number, but does not match the ones the dongle mates with), and what is almost certainly a serial number, "0011001592". Of course since I have your attention, I might as well ask if anyone happens to have a Socket-brand serial dongle that would be available. Anywhere from free/postage to a few bucks would be fine, especially if it's known to work with this older card. Thanks, -ethan

Information on the ADAM computer

by cmurray＠eagle.ca

Glen, I have been an ADAMphile for some 20 yrs. The best information on my favorite orphan computer can be found at mailman at adamcon.org The ADAM community thrives today. Computing forever! Murray-- Message: 10 Date: Sun, 22 May 2005 19:11:18 -0400 From: Glen Goodwin <acme at gbronline.com> Subject: Snagged an Adam To: General Discussion: On-Topic and Off-Topic Posts <cctalk at classiccmp.org> Message-ID: <42911196.7010503 at gbronline.com> Content-Type: text/plain; charset=ISO-8859-1; format=flowed Got it free from a FreeCycle post. It's in pretty good shape, including the printer/power supply, main unit, two hand controllers and keyboard. BUT -- no software or manuals. On power-up, it kicks into typewriter mode. Pushing the right-hand reset button puts it into Colecovision "game" mode. How do I get to the operating system in this beast? Any pointers to a user manual on the 'Net? Parts of the tech manual are available, but the EOS ("elemenatry operating system") portion appears to be missing. Any help, pointers, magic incantations greatly appreciated. Glen 0/0

PDP 11/45 light chaser

by jim＠g1jbg.co.uk

Jay, this is the one I used: Location Content Op-code comment 001000 012700 mov #1,r0 load ro with 1 001002 000001 001004 006100 rol rotate r1 left 001006 012701 mov delay r1 load register r1 with delay 001010 007777 delay 001012 005301 dec r1 decrement register 1 001014 001376 bne -2 continue to decrement r1 until r1=0 001016 000772 br -12 back to 001002 (dec r0) it's not elegant, but you do get to see the lamps light, you can change the speed by altering the "delay" value. It doesn't work to well, as the data display will show the load of r1 as well. Yo should be able to alter it to put the lght chaser into the console display register (you'll have to re-calculate the value of the final branch - it will need an extra two memory loactions, one for the mov display register instruction, and one for the location of the register). I haven't got this to work on my 11/45, as I get a memory address error when I try to write to the display register, though I'm told I should be able to write to it - I think there is a processor fault lurking in there somewhere, or possibly a fault in the memory management module, though this is less likely, as I can read and write to the DL11W serial port.

Kludge Komputer notes and CDC 8092 manuals

by aek＠bitsavers.org

I also loaned him two of the Kludge Komputer Kompany articles from Datamation. They showed up on this list recently too. And I'm certain they will be enjoyed by those who haven't seen them before. -- up now in http://www.bitsavers.org/pdf/datamation Hans, the 8092 mans should be up later today..
