Initial Plus/4 Release

Here's the first release of this project. It is completely untested, so use at your own risk.

Enjoy!

EDIT: This will NOT work, do not use.

Alternative C64 Version

Since most of the non-functional modifications I had in mind could also be useful for the C64 version of this board, I started out with them, before doing the changes that would adapt it to the Plus/4.

The outcome is this board for the C64, which should be functionally equivalent to the original one but which features:

• A jumper that selects whether the ESP should be powered by the rectified +9VAC or by the 5V rail (NOTE: There is no ferrite on the 5V rail, so this might introduce noise).
• 0805 resistor footprints for easier hand solderability.

These changes required the rerouting of some tracks but the board keeps exactly the same size and major component layout, so all enclosures should still be usable.

It is completely untested, so use at your own risk.

Enjoy!
