This is in my opinion the best A500+ reproduction board. It has extras such as:
ESD protection diodes on the mouse/ joystick ports if you disconnect those whilst the computer is still powered on! 🤦🏻♂️ These are installed already by me.
RGB signal boost to give a cleaner picture which certainly monitors. This is not a scan-doubler. These are installed already by me.
HDD activity pin that can be connected to expansion boards like PiStorm or Terrible Fire etc.
