so i received my conversion board from billtronix (awesome piece btw) , and took out my space duel pcb to throw the mh pcb in to test. i bought it "untested" so i was assuming it would be dead, but in fact it did boot.
here is some of the screens that i was greeted too. i cannot identify any errors on self-test, as i cannot read them. i did swap the avg from my working space duel pcb, and vice versa...both had no effect, but the mh avg did play space duel fine. all socketed chips were cleaned thoroughly.
the game does play, and all the sounds work. it is just a garbled mess.
