Hi
I might have a manual someplace that has it in it. It
was a single chip combination of a number of 2901's in one
package. I think it had a 2910 as well. I forget if it
was 4 or 16 2901's. Still, basically an extension of the
2900 bitslice family.
It will be some time before I can dig into my piles to find
a book on it. Anyway, it was still considered part of
the bitslice family and not a uP.

Looking for some DEC stuff for my private collection... New Mexico, Texas,
Arizona area preferably:
Any BA23 chassis (these could probably be shipped)
Actually, BA123/213 would work too
Any H9642 racks
Any SDI drives (RAxx)
Any working RD54s
9-track tape drive--any make that can be connected to a VAX,
i.e. Kennedy would work, though a TU80/TU81/TU81+ would be
ideal, as I already have the controller.
KDA50 disk controller
Any of the following: DELQA/DEQNA, RQDX3, TQK50
Contact me off-list if you have any leads.

There is a 1600 Pan--something_or_other that Kodak makes
that is also fine grain. I've used it to make C size blowups
of astro pictures. It is hard to find but it is available.
Most places I went would tell me that it was only use by
professionals and they didn't carry it. I wish I could
remember that name.

I suspect that it might be very well be a corruption of the story
about Randy Cook's easter egg in TRS-DOS, that showed up in NewDOS
prior to NEWDOS80. That one really DID exist. RS, in TRS-DOS 2.3,
changed "Randy Cook" in the easter egg to "Tandy Corp". It was
invoked by running a boot file as if it were a program, with one
of the master paswords, and pressing 'J'? and 'N'? while it was loading.

That's funny, because the first time I heard the story a few years back, it
was a lawsuit between AT&T and SCO over the rights to unix. (Or was it
MicroSoft and Xenix...???) Should this discussion be moved to the urban
legend mailing list?

Little bit of a problem with that logic...you would want to "accumulate" or "sum" the light from shorter exposures to simulate a longer one, not "average". And if the light is low enough you could end up summing a bunch of "0"'s in any case....
OK, at a mere OCT 20 years I think I'm the youngest on the list - I
started out playing around with NIBBLES.BAS on my dad's business 286
Vectra laptop (he worked in Shipping at HP), I can't really remember
when, but I was young - around three years old. When dad got his 486, I
played extravagant amounts of Commander Keen 4. Started writing tiny
programs in the library at school on the 386 there when I turned 7.
I have fond memories of lending my dad's HP95LX and playing with it,
especially after he got his 100LX. The 95LX was confiscated by my school
and subsequently lost by the teacher, and the 100LX was broken by my
baby stepbrother who tripped over the charger... and gave me two
HP50LX'es...
Had a fascination with 1980s computers like the Commodore 64, sat in the
basement typing BASIC games off the "Learn BASIC" book when I was around
10-11. I think I was about 12 when a friend of my mom's lent me a
machine with Visual BASIC - and I did some very... BASIC stuff with that
too, but rapidly started getting a hold of things
At age 14 I sort-of got a job setting up Windows XP machines for a local
gaming place, where I met Bj?rn Vermo, investor, cctech mainframe guru
and list member, and his girlfriend, Debbie, who told me about the
Informatics library and the books there. I managed to navigate my way
there, and was shocked to find a PDP-7 in the atrium. I did not know
much about big iron back then, so it was a great opportunity to learn a
lot more. And learn I did - I subscribed to this list (first cctech
digest, then cctech, then the full cctalk - addictive :), started
getting into Linux, learning to code a Real Language, learning about
electronics, and classic computing, etc. I found it remarkable how much
one learns when one completely ignores school!
Now I just recently got my very own PDP-11, which I with the help of
gordonjcp over IRC fixed :)
My dream job is working at a museum, maybe even starting a separate
computer museum (which Norway, with a very interesting computer history,
IMHO really needs, but that's another thread :)
Hell, I'd be a building super if they let me use a 360/91 as the
furnace :)

Does anyone else on the list collect mousepads? If so, what is the size of
your collection and do you specialize? I was just looking over some the
oddballs I have in my own collection which is over 600 pads (with a number
of dups. included) and still growing. I collect all types such as those put
out by computer companies, business of all types, pads with liquid/floaters
inside of them, really oddball ones like the mousepad telephone sold by
Sharper Image, odd shapes, and ones that are true artwork done by real
artist (on commission) and children that are cancer patients. JohnK
Very cool. Got it working. It's a clever device that sits between
the terminal and computer. It simply bidirectionally and
transparently passes characters terminal <--> computer, but can
pattern-match text from the computer and send text to the computer
in response.
I'm so advanced here, I don't even have to type in the date and
time, a MACHINE does it for me! Imagine the time savings!

Isn't technology wonderful?
I now have FORTRAN IV actually working now. I did previously make
FORTRAN IV "HELLO, WORLD" run, using the TYPE command, since I had
troubles with FORMAT, but it turns out the troubles successfully
using FORMAT and WRITE were actually problems with the math
library functions. I rebuilt the fortran library with the hardware
mult/div and it all works.
So I found an RDOS KERMIT program source. It's actually the output
of some RATFOR, for FORTRAN 5, but hopefully I can get it to
compile on FORTRAN 4.
My problem is more contemporary.
The kermit source text is on my "terminal" linux laptop. I'm using
minicom. I need to do
XFER/A $TTI KERMIT.FR
on RDOS to input the text, but minicom blasts the text out too
fast. I solved this problem in another world at another time by
writing a "text upload" that dynamically watched for character
echo and self-paced; is there anything like this around?
I guess I could hack something up in Perl, to simply delay 25mS
per character, or something; or extract the CPU card and set the
console speed to 300, bu sheesh, the source is 68,798 characters,
I have to debug fortran4 vs. fortran5 issues as it is, I don't
want to chase down dropped single characters at the same time.
Is there any linux tool to do this sort of console-bootstrap
thing, or a way to coerce minicom? (Delay after newline is
useless, tried that, even 999 mS.)
