Identify this PCB?

I was thinking that it might be a bootleg something.. I have 5 of these boards that are very similar. All have no identification numbers whatsoever..
 
The thing is, that board looks almost identical to a Galaxian board - although the daughter card is different, and there is no solder mask. It might not even be Galaxian - it might be one of the numerous other bootleg games that ran on the same hardware.

If you have a ROM burner, you can read in one of the ROM chips and use RomIdent to figure out what it is (provided it's in the database).

I would double check to be sure the power matches up with Galaxian, and if so, I'd say it's reasonable to assume it matches the Galaxian pinout, and try it out.

Looks like it also has the circuitry for 7 volts AC power input (which is converted to DC) so you may need to carry out an AC to DC mod if powering it with a standard DC PSU (assuming it hasn't already been modded). There's various ways to do this, everything from a simple wire jumper to removing diodes and bridging their locations with wire jumpers. A Google search for 'Galaxian AC DC mod' will give you the relevant info.
