Frank was more likely thinking along the lines of "Bud Light" so he
can put the savings towards a box of replacement ROM boards.

Thanks for confirming the two middle layers as ground and power.

I am getting my 6-layer version of Eagle CAD tomorrow, so I can trace everything in. Once we have this, we can figure out the missing parts on the back of the ROM card (12MB Flash RAM for everyone for a few bucks!), and we can even make new ROM cards with better chips (4 ROMs in one, reflash your firmware, adding features...).
