How many old UNIVAC weenies read this group?
Jim McCullars
Greetings!
I just ran across this newsgroup (again) and noticed a little OS1100
discussion going on. Those were the days! My site left that platform
about a year and a half ago, and I do indeed miss it.
Since we're trolling for old Univac weenies, can anyone here tell me
what a "flip-flop" was? At least that's what we called them when I was
at the University of Alabama (Tuscaloosa) many years ago. In fact, I still
have one.

JK flip-flop?????? Ask a UAH CS professor. Is Dr. Sajjan G. Shiva
still there? Still CS chair? The text he wrote and that we used at
the time "Computer Design and Architecture" went into great detail on
various types of flip-flops.
There are still several hundred OS1100 users (if not more) being
supported. ClearPath has extended the 1100 line once again. It is
only some political groups that would like it to die in favor of other
unproven technologies. OS1100 is alive and well and integrates with
CS and the WWW very well. Of course the politics of the Huntsville
area, government, and contractors made OS1100 a common commercial
enemy. There was and is nothing old-hat about the architecture other
than others have something else that they would like sell in its
place.
I am sorry to hear that UAH is no longer an OS1100 site. As a CS
alumni, I have fond memories of long evening sessions with UNISCOPE
terminals in the terminal room and TTY dialin sessions. Please e-mail
me so that I might ask after about a couple dozen CS faculty and
staff.
Also, I used to work at the NASA Comp Lab on Sperry equipment. I
imagine some of the old crew are still there, just new contractor
masters. A great deal of communications, OS, Exec, FORTRAN, and
assembler work.
Are the University and NASA and the state still using a LAN'ed Cray
"supercomputer"?
Warm ragards.

Though I hate to consider myself old (the standard definition is anyone
20 years or more older than you is old), I have been around 1100 (or the
power of 2 version - 2200) since the late 1960s. There are other
experienced (isn't that a better word than old) Univac people who
occasionally appear on this group. Maybe the old machines are so grooved
and working so well that no one has any questions (or maybe they believe
that there aren't any answers). I for one would love a version of SSG
that ran on the PC, but then again I am known as an SSG fan.
Also, if anyone has questions about the Year 2000 and ways to attack the
problem, I will be gald to participate in those threads (up to a point,
since thats where I make my living nowadays). If anyone wants some ideas
on this problem they can visit my web site (www.sol2k.com) or if you are
there I will be at talking at the Spring UNITE next week.

Well while I think the world of OS1100 as a batch and transaction
oriented OS, they were still a bit behind the power curve in terms of

Controller. We used DDP1100 a bit, but it just wasn't there yet.

I imagine, but I really don't know any of them. You may have worked
with Ken Chaviers, I think he is still out at NASA. We have two former
Unisys CE's working for us at UAH - Larry Morphew and Clifford Gaines. We
also have a guy named Dale Dean who worked with the old defense group that
used to be on Church Street. Dale has come full circle, since his first
job with Unisys was as a computer operator for the Univac service center
that used to be here at UAH (he started in about 1966, I think).

They still use a Cray, but it's not the one that was originally installed
in 1988. And the Alabama Supercomputer Network (which is now called the
Alabama Research and Educational Network) has grown by leaps and bounds.
Thanks for the reply and for the memories.

I guess I count also. Started on an 1106 in '74. I support a 2200 or
actually I ignore it while I support and curse UNIX.

I guess I also belong to this group. I started with an 1108 262K, 2
FH432, 1xFH 1782 1Xf2 and some tapes 7track and 9trk. The symbiont was
Univac 9200.This was in 1970. One of my first projects was a feasibility
study to see if Demand processing had any benefits over Batch.
This was the start. I have stayed with the 1100/2200 till this day and I
still feel sorry for those poor guys that have to work with other
equipment.

Ummm... define "old". I'm only 38, but I got started on EXEC 8, Level
28 (with lots of local code), on 1108's (and one 1110) back at
NASA/JSC in 1978 (lots of 8's in there, hmmm?).

Well, I have been lurking on this newsgroup for about 6 months now and
this thread has prompted me to speak up. I haven't worked on an 1100
since 1986 and I sure miss it! My first 1100 was an 1108A; I
fondly (?) remember remote 1004s, card readers, 432 drums and all that
neat old stuff. My first exec was level 27 and the last one I worked
on was 39r1. The 1100 was pulled in 1985 and replaced with an IBM
3090. Since then it was been unix for me and now windows nt. I sure
do miss working on an 1100; have they changed much since '85/'86?

I remember doing (but can't recall which buttons) stopping the 1108 at
the maintenance panel, clearing a hung I/O channel, and then restarting
the machine. I almost cried when we replaced the 1108 with the 1100/81
and the maintenance panel went away; loved those lights!

Joe, the financial apps at NASA/jsc now run on a 2200/435 at 43R8 with
an HLC. All the DCP/40s on that system are "retired", and the DCP/30s
went to STSOC. I'm not up to date on the systems that run the
simulators - that's a different contract.

Greetings from Microsoft Internet Explorer 4.0 land.
Just putting IE 4.0 through the paces.
Mainframe stuff is nice, but editing on a big box is not the main
attraction. I started with the 1108 stuff when I was in eight grade on
MECC (when it wasn't a commercial company).
Give me a 1100/2200 as a data source backstore for Web frontends, Now

Since no one answered this one, maybe it *was* just a local name we
had for them. Remember the "EXEC 8 Hardware/Software Summary" (UP-7824)?
They were about 8.5" long and 3.5" wide, and were bound at the top. Since
they were top-bound (mine had three metal rings), you "flipped" the pages
rather than "turning" them, hence the name "flip-flop".
No one else used that name?

Not a comfortable feeling. There are some things that Unix
doesn't do so wonderfully. Exec-8 has its own strengths, and
the hardware provides for some *serious* single thread performance-
something the smaller boxen don't do as well.

I started out on an 1100/82 back in '79, working w/ the GCS and
studying the DCP (and later, DCP/40) for use as a front end.
I then worked on the rear-ends- The DataWest Array Processing
System for the 1100/80- for the Sperry-UNIVAC Energy Branch;
I did a fair amount of microcoding of special-purpose primitives
for the APS as well as constructing an optimized panel-i/o
subroutine to optimize the 3D FFTs we were running (1024 element
traces, 256 elements per panel, 64 panels).
Finally, I was dealing w/ 1100s supporting transaction processing,
talking to Collins Front-Ends using MACCOM (yuck!). It was there
that I actually dealt w/ a DCP/20 (on an 1100/60) and noticed that
a half duplex channel works better than a pseudo full-duplex one
(everybody was complaining about terminal responsiveness until I
tried this out between TELCON and CMS-1100; The DCP/20 just went
supersonic and complaints kinda vanished...).
After that, I moved on to Unix systems, still dealing w/ system
issues.
Things I Miss:
- Buffered terminals (I wrote an @FSED in 1980 while at
the energy branch) (though X windowing makes up for a
lot here) (oh, yes, 327x CRTs need not apply)
- @SSG, SymStream, etc (awk isn't so bad, but it took a while
to get comfortable) and the correction file mechanisms
- @MASM (it's nice to cough up a cross assembler in a single
afternoon)
- @OSAM, SIP, @PAR (sar, while useful, isn't as detailed as
SIP/PAR, and I miss the internal dynaprobes of the 1100/60)
Things I DO NOT Miss:
- the qualifier*filename file structure
- fastrand format
- SDF (especially the PRTCN variety- I had to write a pgm
to translate these to ANSI)
- @QUOTA - It was tough to understand it.
There are some things that a mainframe (such as the 1100) excels
at. Remember, @SORT, no matter how you work it, is single threaded
*somewhere*. Many folks don't realize that some things you cannot
throw a sh*tload of CPUs at...

Hey, some of the editors in OS2200land aren't half bad. UEDIT has
split-window editing and can juggle a reasonably large number of files
concurrently. And since I put a simple CSHELL interface in, I can
literally live in the thing for a week (I just type in various CSHELL
aliases a/o kick off various processors from the UEDIT command line,
and since UEDIT saves the entire editing environment on an error FIN,
I do that intentionally when I leave, and simple do a UEDIT,A in the
morning to restore it all and go back to work, bookmarks and everything
all completely intact <g>).
I also find that I'm regularly creating text files on the 2200, then
FTPing them up to my Mac so I can cut-and-paste them into PROFS (sorry,
OV) -- I can't stand BBEdit or any of the other Mac text editors I've
tried. :-)

Inspired, I went home and dug through an *old* box in a closet.
Found it, along with the 1106 Programmer Reference Manual, a
Pascal compiler written on cards, and a 1/2" tape (no doubt
1600 bpi and in @COPY,G format). I don't have the slightest
idea what's on that tape anymore! This is almost like going on

Yep - me too! I modified mine with the little gummy circles to keep the pages
in and gummy tabs at the bottom to index into it. I also have an old UNIVAC
1110 instruction Reference Card that has a nice ascii/field data/octal
character conversion chart on the front.

Mike, I presume that you know that you're asking for something that's
standard product when you say that? We have Web servers native on the
2200, or COTS servers like IIS or Netscape running in the Intel half of
a ClearPath HMP/IX. These can rather easily access either heritage data
& applications, or newly-created databases just for the Web.

Gee, I have a whole pile of them in various flavors. I really like the old
ones with the instruction timings for the 1106 and 1108. Never had the
heart to throw them out. I'm really sorry I tossed one of my old TIP
manuals that was about 50 pages, most of which were instructions for the
AAA screen handler.
I'm really not THAT old, but I did start on a 1401, moving to an 1106 with
channel connected 1004's, F2, 1782 and 432 drums (no disk). (No, they
weren't named, ONLINEFAST2A, ONLINED1782A, and ONLINE0432A).

John Walker, is not just "at AutoCAD"; he is the founder of AutoDesk, the
publisher of AutoCAD. I think he's now living a life of leisure in
Switzerland. Other early principals of the company which the Univac community
might remember were Duff Kurland and Kern Sibbald.

One fellow at AT&T told me that QLP "is as end-user oriented
as FLIT" when I queried him on it's usability.
FLIT = "Fault Location via Interpretive Testing".
FLIT, BTW, was used to format system dumps into a (readable?)
form that an Exec internalist could follow.
CCRs were fun, too.

I still hve my SNOFLAKE and SNOBOL manuals around somewhere.
I think I may even have the compiler on a tape somewhere.
Wonder if the tape will crack if I try to unwind it?
I wonder if I can find a servo to mount it on?.

Anybody else here run on Exec II? We started my first project here
(RALPH, aka RFOR) on a remote 1004 link to NBS in the summer of '67,
about 4 months before our 1108A was delivered, with Exec 15.3 and
Fortran. Then used Exec II ONLY to generate Exec 8 until the sysgen
process worked natively (L19?).

Checking my desk drawer, I find
1) Exec 8 HW/SW reference, both sidebound and ringy-dingy (top)
versions
2) Univac 1108 Operator Guide, for Exec II
3) 1108 (MultiProcessor System) COBOL under Exec 8 Reference Card
[never used :-)]
4) Univac 1108 Multiprocessor System Reference Card
5) Univac Exec 8 Reference Card (Univac Marketing Education)
6) Univac 1110 Marketing Education Reference Card
7) FLIT Level 4R1 Summary (UP-8937)
8) CTS 8R1 Summary (the only other place I've seen Perl's syntax of
'<action> if <condition>')
9) COMUS Level 4R1 Summary
But the real (reel?) find came from a closet upstairs when the
directors office moved: eight reels of 16mm film entitled "Univac
Executive Eight" (Aug 69), Twin Cities TV. Anybody still have a 16mm
projector?
Our last 1100 left around 92, and I do miss it. There were times when
I might have traded some important body parts for the SIL reports from
COMUS; at least I would have known who installed what where on these
little Un*x boxes...

One of the first machines I ever used was the 1108A at the NBS in the
summer of '69. I was a summer intern at the Corps of Engineers, working
with a group whose goal was to maximize the benefit of flood control
allocations. I took the pool car out each day from Forrestal. I have
fond memories of those days.

Sigh... the closest I came to Exec II was when I started as a co-op at
NASA/JSC. They had some engineering programs that hadn't been
upgraded / converted / whatever to run on Exec 8, so they ran one of
the 1108's on Exec 2 for 8-12 hours a day until the conversion was
complete.

Wasn't there some aspect of COMUS/COSMIC than ran under a run-id of AIDS
for a brief while? What did that acronym stand for?

ISTR it was "Automated Installation and Development System" or some

Then AIDS disappeared, the excuse being the "unfortunate" acronym, and
COMUS II came out. We installed it, and found it was a combination of
the two procucts:
- from AIDS: the functionality
- from COMUS: the name.

I don't remember "COSMIC"--might have been before my time.
Seems like the one of the US shops (Roseville? Blue Bell?) made a product
(tool?) sort of like modern-day-COMUS called "COMUS". My recollection is
that it was an unqualified disaster--most of us refused to use it if we
had either (A) tried it once, or (B) talked to somebody who had.
I disremember what the "CO" was for, but I am pretty sure the "MUS" was
"Maintenace (of) UNIVAC software.
At the same time, the folk in the UK developed a similar gadget called
"AIDS" (no recall at all of the meaning. . . . Automatic Installation and
Distribution of Software?) that (legend has it) actually worked pretty well.
AIDS was (my recollection continues) imported and combined with COMUS
(the name was the only thing of importance from the US product, I think,
that made it through the "combination process).
Now. How about "PLUS"?

Charlie,
that wasn't a typo - I did really *mean* COTS (pseudo-standard acronym
for Commercial Off The Shelf), not CTOS (Convergent Technology Operating
Systems, if I remember correctly). I agree CTOS was great in its day
(unfortunately we can't stand up to Microsoft's NT marketing, and NT can
now nearly do everything that CTOS could do 10 years ago), but I'm
talking about something entirely different, I'm afraid.

You must mean Programming Language for Univac Systems (I think I
remember the acronym correctly.) I was at Roseville in the Exec group
when the shift from assembly language to PLUS began. Left before it
penetrated very far, but it looked like most other late 70's ALGOL-like
languages then. I remember that people were into VERY long variable
names in their PLUS programs, then; it sort of gave me the shivers.
I recall that there was a good bit of skepticism among the old hands
that they'd be able to do an Exec in PLUS. Since I've been away from
Exec internals for about 15 years, anybody have an estimate on the
percentage between assembly & other languages?

Russell,
last time I heard, most of it was in PLUS, but they were starting to
switch away from PLUS to c. There's still a bit of MASM here and there,
though. No doubt someone will give you some more accurate estimates.
Colin
TLB
Don't know about lately, but there was about 30% BM/EM masm when I left
Unisys (jumped ship :) in 93 -- the rest was in plus. Some things will
remain in assembler where instructions *really* matter (dispatcher, etc).

Nope....
a rough measure
Symbiont and Facilities inventory are plus (symbiont from 38 and facilities
from the 39 rewrite). Some of the security is in plus; the new xio is in
plus and the AFCB is in pls. Most everything else is in MASM still.
Exec is big and most of the build time is still in MASM. All of the plus
still is imbedded in the third leg of the split and the times still work out
about the same.
The EXEC itself does not have any C but many of the OSG products such as
ELMS are written in C
CMS is written mostly in PLUS with a bit of MASM
(WE just got through going to 45R1B)

I have never heard of a flip flop in relation to the 1100 serie computers.
however flip flop is (as i know it) an electronic term for two coupled
transistors.
the term flip flop refers to the state two transsistors had. one is "on"
and the other is "off"
(high voltage and low). then when a signal comes the two change from state,
and the one in high goes low and the other one goes from low voltage to
high.
I was when i heared about boolean algebra (as venn diagrams) for the first
time.
in the old days the were no chips... !
its predecessor was a flat box of about 4 x 2 x 0,5 centimeter painted in
blue.
these things were made around 1965 by Philips (Netherlands), and they saw a
very big market then.
But the next step was micro-electronics, the chip was invented, so it
flopped.
oke?
h a n s
Jerry Isaacson
A flip flop was in common use back when I did some logic design and
field engineering on the SS90 computer. It wa a board that had a
circuit that , if I remember correctly, maintained one of two states and
