## Component Changes
|
|
|
|
### Replace 12v aux power with 5v
|
|
|
|
This change is for two reasons:
|
|
|
|
1) The 7805 regulator is wasteful, especially when the IIgs only has 2.5a on the 12v rail
|
|
2) The Apple IIe doesn't have a fan connector
|
|
|
|
The fix for this will be to get 5v directly from the Game IO (Paddle) Port, a direct tap on the 5V power supply wire, or from a card slot.
|
|
|
|
This 5v will be used directly via an IC that performs reverse current and over-current protection.
