I have a Flicker Magic which consists of two boards and a VGA output. Its this:

In any case, the one you got on ebay has the 2 missing chips, so my guess is its a Scan Magic. Since the seller described it as a flicker fixer, either he bought it and never tried it and turned around and sold it without knowing what it is, or you got ripped off by a dishonest ebayer.
