This is VERY important.
So far I've come across 5 different types of Saturn boards, and there may well be more out there.
This project documents the modification that will work on the 2 most popuplar Saturn boards - the VA-7 and the VA-9.
These are generally found inside the newer Saturns which have:-
No disk access light and 2 round, grey buttons for power and reset.

 
  If your Saturn is different to this, or is outwardly identical but the board is not marked VA-7 or VA-9, you must not use these instructions to modify your Saturn

Unfourtunately the location of the jumpers you need varies widely between the boards, more importantly the 'common pads' on jumpers also vary.

Even more dangerous is the fact that the power supply also varies between board types.

These instructions can be used as a basis for modding any Saturn,
but if it does not match the Saturn shown - you'll have to
take the principles behind the mod and adapt them for the particular
Saturn board you're working on.
