The Tech:

Quite interesting. This board uses Tengen's MIMIC-1, but in a shrink-DIP package instead of Tengen's usual full size DIP. It's also an odd .4" wide. You don't see many chips with this spacing. Other than that, the pinout is the same as the MIMIC-1 and it functions the same. The 2K of RAM and 74LS00 are used to generate the 4-screen mirroring that this game uses.

See the Tengen 800002 page for info on the MIMIC-1.
