Eugeny has made new versions of the IO, Video and Slot-board to solve known issues and introduce new capabilities. Some added functionalities are S-Video, dip-switch for additional settings on the video board, external power connector on the IO-board, joystick/mouse over current protection, warm boot register on the IO-board, etc.) I have ordered some PCB's and have some extra available for sale (I had to order a minimum amount of PCB's). I only sell them as a set (IO, Video and Slot-board) without the parts. The price for a set is €30 (without shipping). The bill of materials has to be obtained from Eugeny.
