I'll finish your sentence ;) No, a Space Duel board is one socket short
- hence the daughterboard on the original Lunar Battle board. Space Duel
*does* have open spaces for the additional RAM and other sundry bits
that are needed for the scaling. Aside from a few jumper wires, the
addition of a DAC08 and changing a few TTL chips it looks to be a
straight-forward conversion. If someone wants to pour over the
schematics (Gravitar and Space Duel) and give it a try, lemme know.

You will see the Lunar Battle ROMs up on my Atari Vector Rom Archive
shortly :) Just need to make some more readme files. Scott E. owns the
game now and I understand he gave his blessing for the ROMs to be used
in MAME, so...
