Ok, the JAMMA board LOOKS like maybe a Neo Geo one slot, or other motherboard + cart system board, but without any carts. If you can make out the manufacturer then I can pin it down to an exact one. (Could be Neo Geo, CPS 2, Jaleco Mega System, or Taito F3).
As for the pattern board, dunno, probably left over from a previous incarnation, OR it was a test board that came with the cabinet, since that IS a generic cabinet that you have there.
Boards aren't going to be worth too much either way, don't expect more than $20 for either one of them, especially since you can't exactly test them without spending money.
