Good luck. Vista does not run DOS graphics. Vista does not allow text
in fullscreen mode. My good old DOS text editor runs like a dead dog
in a console window... Eventually you will not have a choice. Old
stuff just won't run anymore - or emulation will extract a large
penalty in performance.

IBM has done somewhat better at supporting old systems.

Programs compiled (or assembled) for OS/360 over 40 years
ago will still run under current z/OS systems. One that
I have heard is the PL/I (F) compiler. The Fortran G
and H compilers should also run fine.

Z/OS is almost indistinguishable. I think it's 1969 every time I log on.


Rumor has it that someone on Wall Street still runs a 1401 emulator
written in 360 code!

:) In reality, Z/OS has UNIX basically, substantially embedded, so you have the "best" of both worlds. Even on VM, you can mix UNIXisms with VMisms under CMS. It's a really good environment for exploring what you like or dislike about unix or VM.
