Hi
When you obtain any Amiga the user-startup file probably should be your first port of call to try and work out the history of the computer and see just how the previous user used their machine. Also Tool Types can be edited and various scripts written. Customization is the great strength of the Amiga, but can be a touch puzzling when machine and peripherals become severed.
Hope that makes sense.
