List:
This is the first time I've run across a bunch of double-sided 8"
double-density floppies in RX02 encoding. I'm assuming that this is
what's known as the RX03. The system is identified on disk as RT11A.
Does anyone know of a program to extract the files from images of this
sort (1,025,024 bytes: 26x256 sectors/track, 2 sides, 77 tracks)?
I've tried John Wilson's PUTR, but it hangs when it sees the image--I
can mount the image, but then anything after that just hangs the program.
I'd prefer a Linux program, but DOS/Windows would be fine. Otherwise,
I'll sharpen my pencil and get coding...
Thanks,

Hi DEC Enthusiast's,
If I were to have to decide on just one model DEC PDP system to run in a DEC
Emulator, which one would be the most useful, versatile and has the most
software available for it?
I have only ever used a real PDP-8/e system way back in high school so I'm
not up to par on any other model of DEC PDP system and I only know BASIC on
the PDP-8/e so not much there either.
I hear a lot about the PDP-11. I found out that there were 16 major PDP
models at one time so I'm not too sure which one to pick.
I built Oscar Vermeulen's PiDP-8/I which I'm waiting on 1 part for. Other
than that project which is in a holding pattern at the moment, I have no
other PDP anything running in any form.
Back in the day when Bill Gates and company 1st started out, I had always
wondered how they developed their very 1st software program - Altair Basic.
I was pleasantly surprised one day when I saw a B/W photo of a young Bill
Gates bending over the operator at what looked like a very small computer.
Maybe it was just a terminal. I don't remember. I understand they did
software development on a DEC PDP of some sort.
Finding this out regenerated my interest in the DEC PDP line of computers.
I have many projects in the works already so I decided to setup a software
emulation of just one of the DEC PDP models. I have heard a lot about the
PDP-11 which if the information I read is correct was 16-bits. My PiDP-8/I
is 12 bits. I understand the PDP 10 was 36-bits and the PDP-15 was 18-bit.
The PDP-11 is the model I hear the most about.
I also have some experience on some version of a VAX when I was in the Air
Force so I'm thinking of getting a VAX emulation going at some point too.
So if I'm going to do this, what suggestions, pointers, experiences,
etcetera do you guys have for me. I am very interested in the DEC PDP
equipment though next to no experience so I have no basis to make a
decision. This is a serious request so I would definitely like to hear what
you all have to say. If you have read this far, thank you. Take care my
friends.

Hi folks,
As the subject says. It's been stored in a garage for many years but is in
pretty good condition. Free for pickup.

I'm reminded of a unit manager at CDC that I worked with for a time.
His first job at CDC as a fresh EE out of UofMinn was to measure all the
loops of cable on the backplane of the then-new 6600 to which Seymour
had attached tags that read "TUNE".
One marvels at the fiddling that must have been involved getting the
thing to run. Fun with taper pins...
Cray was certainly a character. Another associate regaled us with his
experience outside Seymour's lab in Chippewa Falls, sitting with a
couple of others in a car on a cold dark winter night exchanging code
and listings with Cray's daughter at the door. He was not about to let
them inside...

I have several Q-bus boxes available:
BA11-M 4x4
MA11-N 4x9
BA11-S
BA23- no cases right now, a few have rack mount kits, some I'll hang on to
till I find the
micro vax boards. Looking for offers.
MOST CAN BE SHIPPED! Probably under $100 in US.
All boxes can be configured within reason, but I am getting short of
memory, in more ways than o
one...
I might be leaving Illinois and going to Baltimore, maybe Virginia, then
north to the Boston area, back through NY, through Canada, Detroit, and
back to Illinois. I could be leaving as soon as next week.
There is another list member coming through here from the east coast and
going to Denver and back. Hopefully he'll junk in here...
Thanks, Paul

they claim FIRST ACOUSTIC COUPLER IN 1970.... nah...
GE 1968
My customer has an Olivetti
terminal that he wants to use
on GE Time-Sharing Service.
How much does our acoustic
coupler cost and what is the
rental fee?
The TDM 114 acoustic coupler
rents for $25 a month (including
maintenance by service
shops) and sells for $395. The
TDM 115 acoustic coupler costs
$495.
Aug. 1968 GE service Note - time share etc
Multi-Tech says...
1970: Dr. Sharma founds and incorporates Multi-Tech Systems, renting new
office space in the basement of the Schneider's Drug building in
Minneapolis. He sells the world's first acoustic coupler to Professor Schmitt,
inventor of the Schmitt trigger, for $300.
worlds first? hmmm... Not.
Remember too the Deaf had acoustic couplers prior to 1970 also!

The Tubbs fire consumed the collected archives of William Hewlett and
David Packard, the tech pioneers who in 1938 formed an electronics company in a
Palo Alto garage with $538 in cash.
More than 100 boxes of the two men?s writings, correspondence, speeches
and other items were contained in one of two modular buildings that burned to
the ground at the Fountaingrove headquarters of Keysight Technologies.
Keysight, the world?s largest electronics measurement company, traces its
roots to HP and acquired the archives in 2014 when its business was split from
Agilent Technologies ? itself an HP spinoff.

(My added note) And.... this is why I continue to stress multiple
caches of copies/scans of historical material... and sad... as in this case
here is someone that could have footed the bill and not missed the money to
do it.
