I doubt that the alphabook is more than 10 years old. 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 :(

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 :).

This came across the Virginia Tech Technical Support list server today:
There are 10 types of people in the world.... Those who understand binary,
and those who don't.
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

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.

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
