[MAME]

Grand Tour
IGS, 1993

This game probably runs on the same board as IGS's IQ Block.
Two of the PALs are labelled GRAND3 and GRAND4. However, there may be other 
games that run on this same PCB also, since three of the PALs are 
labelled AF1, AF2 and AF3, meaning the main/first game to run on this 
hardware was called A-something F-something.
