Run Older OSes in Mac OS X

System 1 is a so old version that won't run on any computer (PC and Mac) now because its architecture isn't supported. Also, it can't be virtualized, but even virtualized, you won't be able to use it. In conclusion, it's impossible to use System 1

Why free, isn't it worth anything?

Not going to happen. Your best best is buying a vintage system.

System 1? From the mid 1980's? The best you can do is System 7.5.

Hey maybe the guy has a Motorola 68000 processor.
