Depending on the MPU you have on your machines, I believe the Hot SHOT All About the Money will work on any MPU. The 15 Reel version with the Blazing 7 theme really requies the 1Ghz mpu to work without stuttering. I also believe the hot shot frenzy version will work with at least the 512MB MPU.
The Clear card depends on your OS version. If you look up your bios version and do a search on this site, you will find the information.
