Ok, the code for the basic simulator is now available at:
http://www.ljw.me.uk/ibm360/vhdl/
If you have a Digilent S3 board then you can download the "bit" or
"mcs"
files to program it directly.
I haven't yet documented the external switch wiring, but if you run it
as is you can use the onboard switches for Reset, Start and Stop.
Have fun!

Sorry about the lack of video quality, but I'm sure you'll get the idea.
If you want to know more, you can get the FETOM Y24-3360-1 from
Bitsavers (or a mirror!) There is a front-panel layout on p6-2 of this
manual, which may help in deciphering the panel lamps.
The program being run is The "Indian" Problem on p73 of the Introduction
to System/360 Assembler Language manual SC20-1646-6, also on Bitsavers.
It is loaded at address 100.
I am in the process of readying the VHDL files for release - tidying up
and adding GPL headers at the moment. They should be available within
the next week or two.
