In System 6, you use the Control Panel under the Apple Menu to adjust functions like mouse-tracking speed. These settings are stored in a chip on the logic board of your computer in a dedicated place called Parameter RAM (PRAM).
You can reset your computer's PRAM in System 6 by holding down the Shift-Option-Command(Apple) keys simultaneously while selecting Control Panels under the Apple Menu. The computer will present you with a dialog box informing you that you are about to reset the Parameter RAM. The Date and Time settings are actually read out of PRAM before it is zapped, then written back in afterwards. The next time you restart your computer the Control Panel will be set as follows:
