This is sort of off-the-wall, but does anyone know if there are any emulators extant for my other favorite 36-bit machines - the Univac 1100 series? Yet another one I might try to work on an emulator for, assuming I ever retrieve my docs from my mother's house ... Of course, I don't have a copy of OS1100, so I don't know what I could do with such a thing.... (And, you can still buy a lot of this documentation, too - it's still listed as available, and purchasable on-line, on Unisys's web site...). --Pat.
