Actually, Jamma is 6 pins with a break (key), then 21 pins.

It may well be a Jamma bootleg as they are customarily unkeyed. The fact that there is no brand name on the board supports this view.
Sega System 16 PCB's also have a 28 pin full row, but original boards do have the brand name silkscreened on them. All the System 16 bootlegs I've seen had a jammatized edge connector though.
