Can I slow down my computer to play older games?
Yes and No. Today computers are built for speed, so the hardware really won't let you slow it down. This is where software comes in. There are a couple of software packages that do exactly this. They run with your older programs and allow you to slow down your system. When you exit the program your system returns to normal.

The above sites are just 2 of the available programs that will allow you to do this, I'm sure there are more out there.
