I have an original printed copy of the reference manual for the 90-column version of the Univac 1004. The machine has always fascinated me. I've been toying with the idea of implementing an emulator for it, so I could try my hand at programming it.
I've seen a few references to an extremely complicated plugboard program for the 1004, called "Emulator", that effectively turned it into a stored-program computer would read a program from punched cards and run that. I can't even begin to imagine how that could be done with 31 program steps and 961 words of memory. But apparently it was very popular. People would wire up an "Emulator" plugboard, plug it in, and never need to change it ever again.
If anyone knows where the details for making an Emulator plugboard could be found, I'd appreciate it.
