He’s had great luck with the IBSYS distribution from Paul Pierce; in particular, he was able to get the code compiled by the Fortran II compiler to execute.
It turns out the Fortran II compiler writes out intermediate files to tape as individual records not followed by the customary tape mark; it was necessary to tweak the simulator to handle this the way the original hardware did.
Rich’s enthusiasm inspired me to finally obtain a copy of the Smithsonian’s Fortran II listing — this is a version for the IBM 704, which does not have I/O channel — it is the machine for which the original Fortran I compiler was written.

I migrated the IBM 7094 simulator running IBSYS to a new machine and it is now available again with a new URL.
The IBM 7094 simulator running IBSYS, which was mentioned several posts ago, will be going down for a little bit while I move it off a shared hosting plan to my own server.
As I mentioned in a previous post, with some tweaks to the do_ibsys.txt file it is possible to run IBSYS on the SIMH IBM 7094 simulator.
The IBSYSoperating system was a more comprehensive monitor that could run many different software packages depending on the needs of the current job.
If an IBM 1301 disc drive or a 7320 drum storage unit was available, then IBSYS could operate with only four drives.

7094 Emulator(Site not responding. Last check: 2007-10-19)
The emulator can load and start the IBM 7094 operating system"IBSYS", allowing some simple commands to be executed, but more complex jobs such as the compilers do not yet work.
Operation of the emulator is quite straightforward, all items on the form have decriptive hints/tooltips.
The emulator incorporates a scripting system which will run a small demonstration, making it very easy to see some activity straight out of the box.

When we first got the 7090, government surplus (from the David Taylor Model Basin), all we had, in the way of peripherals, was the card reader and the printer.
The tape drives were donated by Columbia Records with an entire IBM 7074 system which was cannibalized for parts.
The IBSYS nucleus has been assembled with this version and run under the s709 simulator.

If you have an extra or unwanted copy of any official manuals or documentation on this operating system, please send them to: Milo, POB 1361, Tustin, CA 92781, USA.
Note: I am looking for a fan of IBSYS who has the time to check this web site for completeness and accuracy regarding IBSYS.
Just check through the site about once a week or so and report back with any information (including the URL of the web page you are reporting).
