Got me an ADDS Envoy 580 (at least, I'm pretty sure it is -- it has no
model designation apart from "Envoy" but looks identical to Jim's pictures
at http://jimsoldtoys.blogspot.com/2016/05/adds-envoy-portable-terminal.html
).
It's non-functional at the moment so it's going to need some repairs, and I
can't find much on it -- anyone have anything?
Thanks,
Josh
An ad was emailed to me today with an interesting item: RCA 1802 processors. I thought there may be some folks here interested:

Hopefully its working. Why do this? I had to shut off the

Hello,
Can anyone please point me towards a copy of the Tapestar utility package
for DOS? I have already contacted Qualstar and they cannot help. TIA!

Jerry Reich has brought to my attention the operating systems written by
Computer Science Corporation (CSC) for its Infonet time-sharing network.
In the late 1960s, CSC developed CSCX, which was a highly modified EXEC II [*]
with time-sharing and multiprogramming capabilities. CSCX later evolved
into the CSTS time-sharing system used on the Infonet 1100s throughout
the 1970s. Commercial time-sharing networks were widespread during the
1960s and 1970s.

EXEC II is a discontinued operating system developed for the UNIVAC 1107
by Computer Sciences Corporation (CSC) while under contract to UNIVAC
to develop the machine's COBOL compiler. They developed EXEC II because
Univac's EXEC I operating system development was late. . .
EXEC II is a batch processing operating system that supports a
single job stream with concurrent spooling.

I have reason to believe that my very first exposure to digital
computers (in the spring of 1969, at a high school in northern
Delaware taking advantage of a Federal grant to equip a room
with some teletype machines and acoustic couplers) was to
"Conversational Fortran V" running on a Univac 1108 at Computer
Sciences Corporation. Presumably the operating system was CSC's
own modified version of Exec II (CSCX) rather than Exec 8,
but I believe the Fortran V language processor would have been the
same in either case. That taste of high-end timesharing was a
luxurious experience, never to be repeated -- the following year,
those same teletype machines were connected to an overloaded
IBM 1130 at the University of Delaware running BASIC.

For you Fortran folks, I need to explain Fortran V.
Based on Fortran IV, Fortran V was implemented on Univac 1100-series
hardware (and probably other Univac systems such as the 494) by
Computer Sciences Corporation in the late 1960s. It extended Fortran
to include parameter statements?basically a way to define constants,
conditional compilation, and statement functions?basically macros
that produced in-line code.
In 1970, I went to work for Computer Sciences Corporation working
on systems testing of a new timesharing system they were developing
called CSTS. While some of my work was done in assembly language,
the majority was done in Fortran V. For me, it was the "best scripting language"
I had available. (It was also the only language I had available on CSTS
itself for a while.)

Does anyone have any information on Infonet, which was a timesharing
which CSC put out?? I've got some info that it had a timesharing service
called CSTS and would like info on that.
I've got info on the original version of the Pick system which IP was
owned by TRW and was called GIM.? The CSTS Infonet service provided
access in some way to IGIM, which is in a manual I just obtained.
So I want to know if there is any CSTS manuals or documents (ideally)
anyone may have.
Secondly it looks like rather than IBM mainframes for timeshare, the
systems that Infonet shared were Univac 1108s.? So looking for verifying
that.
Especially if the systems were all Univac was IGIM running on the 1108.
The time frame for the manual is 1974.? GIM dates from 69 to 70 from a
TRW contract.? Actual product was obviously running in one form in
1974.? There is information that it ran on PDP 11s as well in another form.
While searching for information with Google, I found some court
proceedings, including a precedent related to RICO charges on
individuals in Infonet.? If anyone finds the original indictment, or can
get to it on pacer, I'd appreciate a copy to read, or send message, I'll
supply the citation.? A better source like Pacer probably will retrieve
the original indictment.? I only find a decision which was reversed
related to the indictment.? I suspect there would be a lot of history in
the indictment around the 1980 ish timeframe of the indictment about how
CSC ran Infonet.
Short story on what you will find online a lot of spots is a precedent
set by the 4th Circuit of Appeals which resolved a technicality about
whether individuals and corporations were the same WRT charges.? The
ruling that RICO applied to individuals and not corporations was filed
by a trial court.? But the appeals court said that the actions if they
constituted RICO by individuals could be go back on the corporation they
operated in was the precedent. Obviously not a good one for corporations.
Thanks,
Jim
Is it classic enough to ask about on this list?
A friend of mine finds himself in the awkward position of being asked to
take on some RPG programming, but knows nothing about it.
Can anyone here suggest some good resources for a crash course in RPG?
Yes, any web search engine will throw up a lot of hits, but I'm hoping
someone here can help select the most useful ones.
Hi,
Would anyone happen to have or know the whereabouts of a technical manual and/or schematics for a Zetaco SCZ-2 controller?
Or the same for any other Zetaco SCZ (hoping that they all used the same back-plane presentation :) )
Many thanks

To continue validating modem functionality, I think it makes sense to
set up a closed loop phone system in my lab that will function well
enough to allow modems to connect to each other (dial tone, ringing,
busy signal, etc.).
I know I can probably whip something up with a 9 v battery and a piece
of cable with rj11s, but I think that will fall short.
That said, I went out to eBay to see if I could source a 2-8 line
something to help, and got smacked around with my lack of telephone
system knowledge.
So, any ideas (or links to eBay auctions) of brands/models/etc. I should
focus on?
Also, if anyone has any modems lying around gathering dust, I probably
should source a few more models. tcpser handles Hayes "+++" spec
correctly, but I should probably support TIES as well, to cite one example.
