I know that this is the Data East club, but is there anyone that could help me with a Sega Frankenstein issue?
It does have the same board set as Data East games and this club has way more members
If it is not okay to post this here, please ignore haha
My game only has 1 other real problem left: Frankensteins head does not work.
The head motion board does not get the correct input from the cpu board.
Connector cn3-1, cn3-8 and cn3-9 on the cpu board should give the clock, data and enable signals but they don't.
Thinking the problem might be the 6821 on 11B (closest to the connector) or a component that is an input for it.
I do have an oscilloscope and voltagemeter, but I could really use some guidance from someone as I'm stuck..
I also asked it in a Facebook group but it did not get me further a lot.
The game plays perfect 100%, except for the head.
