yep same goal it seems hunt will be hard for us three
. polderarcade has been speeding to successfully find 6 carts , it's litteraly like buying the whole world stock
. took me about 2 years to source only 2 motherboards !!
. i saw months ago (with the sega number) a triacs board on ebay. .. at glance i would have never figured it was that ! (because the fans were missing..)
the only electronics parts in the cockpit visually are : triacs, drive board, 5volts card, sound card and the small things & ribbons around psu's.
i tried few times to increase the 5V, but it didnt help my machine to go good..
