              HD38882PA06

      I think HD38880 is a CPU/MCU, because the game just sends it a sound command (0-0x1a)

      couriersud:
         The chips above are speech synthesis chips. HD38880 is the main chip
         whereas HD38882 is an eprom interface. PARCOR based.
         http://www.freepatentsonline.com/4435832.html
         Datasheet lists no parcor coefficients

 About GotYa (from the board owner)

 I believe it is a prototype for several reasons.
 There were quite a few jumpers on the board, hand written labels with
 the dates on them. I also have the manual, the game name is clearly Got-Ya
 and is a Game-A-Tron game.  The game itself had a few flyers from GAT inside
 so I have a hard time believing it was a bootleg.

----

 so despite the fact that 'gotya' might look like its a bootleg of thehand,
 its more likely just a prototype / alternate version, its hard to tell
