This board is only found on one cart- Gauntlet. It uses a 2K RAM and a 74LS00 chip to map it in with the 2K in the NES console to produce an even 4K of nametable space. The Nintendo-made Gauntlet uses a single 8K RAM with A12 grounded to get 4K of nametable space. See Here for information about the MIMIC-1.
