I just received a "working" Tutankham board from QuarterArcade.
(they've been awesome so I'm going to assume in good faith it works as stated when purchased.)
I am using the Tutankham specific Jamma adapter from Bob Roberts.
And I'm getting this rug pattern that varies between a few colors like purplish, greenish, redish, etc. and has a few dots that move around on the screen.
Anyone familiar with what this means? (I don't have any other Konami titles to reference nor do I own schematics yet).
--i should mention that this same cab setup works fine with a multi-board and a moon patrol board/irem-jamma connector. so I'm confident the cab setup is OK.
Any insight where to start? I'm hoping it's something simple like a voltage adjustment
--switching powersupply is putting out 5.1 volts at the pins on the Konami board.
--the -5 is running to the first pin on the board, parts side nearest ribbon cable
--the +5 is running to the farthest pin on the board, parts side-farthest from ribbon cable.
Thanks.
