As my first post as a contributor here, I’d like to point attention to the fact that MS’s Virtual PC 2007 (both desktop and server editions) is now available as freeware–good news for those running 98SE like I am, in Vista. It works in Vista, but isn’t as stable as it is in XP–still good enough though for 99% of those out there. Have fun!
