GPI Game Interface
GPI Game Processor card, front
GPI Game Processor card, back
These two cards are believed to have been used in A2000 based video gaming machines manufactured by Kenilworth Systems. The first card which is Zorro II, appears to be the primary interace whilst the second card which is ISA (probably uses the ISA slot for power) is the processor board containing a Z80 CPU, some memory and possibily some ROMs for holding the firmware. It is likely the interface board also connects to the processor board.
