Univac emulator?

[Gary]

I know there was a university working on a Univac on a chip project,
but does anyone have a software emulator for the same?

Tnx Gary

Why would you want to emulate univac? It didn't do anything other than add.
Besides, it was all hardware, from what I understand.

And,if I remember correctly, the Univac used the EXEC 8 OS.(Is this right?)

Besides, what do you think emulation is about? Resurrecting old, slow,
dead systems so we can sit at our new, fast systems and say "I remember
when...".

Mmmmm...I remember the days when a computer was installed with a crane.

I suppose you're right... I just don't "remember when" I was on a Univac,
since I wasn't born then. It's cool that it had an OS... I didn't know that.
Thanks. Guess I'm getting a little rom happy (If I can't play games on it,
it doesn't need to be emulated sort of thing.). From what I've seen, it's
pretty well documented, so it can't be too difficult, can it? It'd be even
cooler if it had a utility that can create "virtual punchcards" That you
could make yourself and try on the emu. To any potential emu-author... good
luck!

The basic mode instruction set on current model Unisys 2200-series
mainframes (and some of the Clearpath boxes) are very close to the
1108. Though MASM is a good deal better'n Sleuth. :-)

OS2200 is still called the EXEC. :-)

I would love to see such an emulation myself, since I'm curious about
the 2200's ancestor (and the 1100's ancestor for that matter, since I
used those in college and at Unisys as well as now while I'm at my
current employer).

Perhaps I should have added the Eniac or the Model 1 relay Calculator.
I tried to find old machine language instruction sets on the web, but
to no avail.

Tnx anyway Gary

I would say historical interest, and the idea that a huge amount of old
software could be found to run on such machines, usually for free.
The pdp-11, long dead, could occupy you for years with interesting
software.....

Greetings, one and all.

Univac, Eniac et al. had a contempory, built at Cambridge university
around the 1949 timeframe. Went by the name of EDSAC and supposedly was the
first to be able to store programs internally for use by the machine.
For those that may be interested, it has been emulated, though the author
refers to his program as a simulator. Much of the original software has been
preserved and is included with simulator package.
Included is a circa 1952 version of Tic tac toe, (possibly the first
computer game?). For those looking for a challenge, I would recomend it. In any
event, EDSACPC500.exe is a most interesting software package and according to
the docs, it is freeware.
It can be downloaded at:
ftp.dcs.warwick.ac.uk/people/Martin Campbell-Kelly/EDSACPC500.EXE
Thats no error, it comes as an exe file, not a zip file.
I don't have the URL at hand, but there is an associated web site that
provides history etc. That ftp site is a little fussy, it took several tries to
get on for the download.
Good Day!
