My thinkpad N40 is from 1994 and surely the alphabook is faster than 50MHz and thus younger? According to google it has a 233MHz 21066A and according to my memory it should have something like a 166MHz processor, but maybe there were different versions. There's also a HP-UX version, the Precisionbook, which is very similar to the Alphabook. A bit more collectible is this one, I forgot to bid :( http://cgi.ebay.nl/ws/eBayISAPI.dll?ViewItem&item=2042227517&rd=1 Also look out for the RS/6000 thinkpads and the Silicon Graphics laptops (probably only sold to the military or something like that, I've never seen one for sale). Sparcbooks are just too common :). greetings, Michiel ps. For finding information on Alphabooks use www.archive.org on the tadpole and the rdi site.

Anyone Care About RT-11

by jhfinepw4z＠compsys.to

In regard to the Freeware CDs for RSX-11 and RT-11 I have now finished the verification tasks that I feel are needed to ensure that I am producing correct images. I will be making some 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/ I have finally been able to reproduce all 3 CD labels. The 2 RSX-11 labels are quite well done. I hope to improve the RT-11 label - it has all the information, but the label is about 1/4" off centre. If I have not been able to obtain a better copy of the RT-11 CD labels by the time the CDs are being made, then I will just use what I have. I have also been able to get to the post office and check a sample package for the postage. The total amount in US dollars (all inquiries but one have been from the US) will be: ($ 5.00 / $ 9.00 / $ 12.00) for (1 / 2 / 3) CDs when I use standard CD-R blanks. In addition, I understand that Black Label CDs have a longer shelf life and are available at Business Depot. If anyone wants those instead, add $ 1.00 for each CD that you are requesting. Thus that price range will be ($ 6.00 / $ 11.00 / $ 15.00) 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 add about $ 1.00 should be sufficient. If you are receiving this notice via a public list, I will send you my mailing address when you ask me to burn the CDs. Sincerely yours, Jerome Fine -- If you attempted to send a reply and the original e-mail address has been discontinued due a high volume of junk e-mail, then the semi-permanent e-mail address can be obtained by replacing the four characters preceding the 'at' with the four digits of the current year.

What about DOS-11? (was: Does anybody care about XXDP?)

by lists＠subatomix.com

[CCers: found this on info-pdp11, though it might be good on CC] On Friday, August 2, 2002, Frank Arnold wrote: > DOS-11 was (to the best of my knowledge) the predecessor of RSX-11D, and > more or less the first disk-implementation of the famous > "papertape-programming software package" for PDP-11. I haven't heard much talk about DOS-11 or DOS/BATCH (same thing?) on the various lists. Is that because nobody cares to mess with it, or is it because it and its manuals are unobtanium? I have about 200 or so DECtapes that came with my 11/20, and I believe that DOS-11 and several versions of FORTRAN-11 are stored on them. The previous owner also believed that he left DOS-11 running in the core as well. This is going to be a fun machine to play with when I get around to it. -- Jeffrey Sharp The email address lists(a)subatomix.com is for mailing list traffic.

Great Find

by kdowd＠navix.net

John, The Logi-Tran 4 was the follow on to the Logi-Tran 2. I used both to teach EE370 in 1979 or 1980. As you've no doubt learned by now, it's basically a "50 in 1"-ish logic trainer with spring connectors, switches (inputs), lights (outputs), and of course, the logic ckts themselves. It was a great trainer for our digital lab (I was the TA). I remember making a 4 bit calculator with one of my more talented students by hooking up a Logi-Tran 2 and a Logi-Tran 4 (we used lots of gates) side by side. If you've let it sit because of the lack of a manual, just start setting up the ckt emulation of a logical statement (I seem to remember that the Logi-Tran used NORs and NANDs). There was some limit on the output drive of each gate, but my memory doesn't have all the details. Hope you have had fun. Let me know if you get bored with it and want to get rid of it. Later...

Can someone direct me to some documentation for this computer? Maybe a owners manual. Also, I am looking for the specs on the co-processor and ram especially. Happy Computing, Alan
