A friend of mine has a Mac Plus that is is really good cosmetic condition (Next to no yellowing!) and it has the original keyboard. Unfortunately there are a few problems with his Mac Plus: 1) There is no mouse with it (a big downfall) and 2) it rattles when you move it. My questions are: 1) Is there any other device that can be used in place of a Mac Plus mouse (eg. Commodore 64 Joystick perhaps?) and 2) Is the rattle going to be detrimental to the system, and if so, what could be causing it and how could it be fixed?
