Thanks for the reply. I was beginning to think my post was written with invisible ink.
I've been searching to the far reaches of the internet and ebay for a manual, but so far have been unsuccessful.
I got the cab basically complete except for the monitors. It is a dual sit-down cab. I could power it on and hear the music and sound, hear it respond to the buttons, pedals, etc. I just had no monitors in it to test the picture. I actually only wanted one of the steering wheels, but decided to use the parts to make an xbox driving cab. I'm pulling everything i don't need out of the cabinet, including the small boards above. I want to know what they are so I can decide if they are useful for hacks, mame cabs, etc. Or, if I decide to put them on Ebay, i'll at least know what they are.
Thanks for the suggestion on the other forums. I'll try posting there or contacting the other byoac member.
Thanks,
Hatrick
