LOL! I actually like trying out different OSes. I have a VM that I can load them into, test them out, and keep or discard. I'm currently working on creating a DVD image that boots into a menu that contains multiple Live CDs. At the moment, I have 8 distros, and have only filled half the DVD.
I thought CP/M might be a cool addition to that.
Do you have Minix and Plan 9? 8^)
