Many of the first generation of programs were written with software timeing loops. Faster CPUs made these programs unusable. The C robots game would be over before you could even see what the contestants were doing. The turbo button made these programs more useful. Even today, this is a handy "cheat mode" with some games. Mark Browne <Snip - sad tale> I pressed the turbo button, the turbo light came on, and my server sprang back to life. A whole week of head scratching and it came down to this: when I moved the server, I bumped the turbo button. Apparently this button turns a 486 into an 8086. So I ask, where did the turbo button come from and what is its intended purpose? -Brian
