And, with SYS, you can tell it what "drive"
to pull the system files
from, so you could stick them on another hard drive in the machine and
do SYS D: A:, and should end up with the version of them from drive D:.
You might (probably can) be able to get that to work with copying older
DOS versions.

THIS I did not know! Maybe SYS would work after all! Great tip,
