# 1.4
## 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.
## Layout Changes
For a brighter LED, you have the option to choose
# 1.3.2
Move External LED connector closer to edge to clear cable plugged in to J1.
