It expands the existing two joystick ports to 4.
Connects to the user port.

Compared to the very simple adapter made for the Amiga that has only leadouts, the C64 requires slightly more complicated electronics, since the C64 user port does not have enough standard connection points.
That is why it is necessary to use a multiplexer chip, which the C64 actually switches here and there, so it queries one of the connected joysticks, then switches the multiplexer chip and reads the other one.
This does not apply to the fire button, only the 4 directions are multiplexed. The fire buttons are hardwired.
(This is the standard hardware solution for C64)
(I send it fully assembled, ready to use.)
Is 100% compatible with Protovision design.
