Inverted the logic of the power and FDD LEDs: the firmware pulls the lines now to GND, if we want the LEDs to be ON. Reason: The original Commodore 65 prototype keyboard has a very strange 12V LED circuit, which cannot be driven by the STM32 on the DM65PIC, so we needed to do some hardware hacks. This firmware revision is compatible with these hardware hacks.
You might want to stick to firmware revision #2, if you're keyboard has LEDs that behave "normally" or if you just don't care about the LEDs.
