Partial success tonight. If you remember the machine I have is machine B which I believe is @sunking’s old machine an early prototype.
Has the new computer running the 1.2 code, and the timebandit LEDs and is 100% playable minus the alien head.
I ordered the production alien head and tongue board from “Mats” via free-play.se.
I also acquired a jaw board from another source but it didn’t have code on it.
mavantix and I made wiring harnesses from scratch based on the sample production machine we had. Machine A.
The tongue actually works.. in ambush multiball picks up the ball and everything.. yay!
The jaw however doesn’t. One thing I noticed is that my machine’s top PCB where the xeno connections are, the 12v connector is upside down. My game constantly resets when this connector is plugged in, flipping it over doesn’t seem to do anything.
Could be I’m flashing the code wrong, the wiring harness is wrong, the jaw pcb code isn’t flashed right.. or the top PCB has some kind of deviation that makes it not work... I guess the next step is to breadboard this thing and try different variations...
