I've received from a friend a MARS II chip that looks like it could be a clone. It was purchased in the Middle East and thus I can't get hold of the supplier. The markings on the chip are as follows "MARS II" and below, "M320-L8". The component layout is different to the Mars II diagrams on the 'net. The connection layout is the same. Does anyone know if it uses the same wiring as a Mars II M302? Will it be able to work with V7-V10 consoles?
