The Widgetboard (DM65pic) is the breakout-board for connecting commodore keyboards, joysticks an hopefully someday diskdives and expansioncards to a Nexys A7 - based MEGA65.
The DM65pic is completely open source, so it can be built and developed further by everyone.
Schematics and all other information is available on github.
