Notes:
* All chips are 20-pin 0.3" PDIP
* Register $8000 is at $8000-$BFFF
* Register $C000 is at $C000-$FFFF
* ?? is unknown input, tied to GND in all cartridges
* BF9093 is used in 64 kB / 128 kB / 256 kB NES & 256 kB Famicom singles ([[iNES Mapper 071]] [[NES 2.0 submappers#071:_0|submapper 0]])
* BF9096 is used in NES/Famicom Quattro multicarts ([[iNES Mapper 232]])
* BF9097 is used in Firehawk ([[iNES Mapper 071]] [[NES 2.0 submappers#071:_1_Fire_Hawk|submapper 1]]) and in 64 kB Famicom singles (pins 17, 16 are not wired here)
* CIC stun latches inverse of CPU A0 when writing at $E000-$FFFF
* Pinout from [http://kevtris.org/mappers/camerica/ Kevtris] is not accurate

Notes:

  • All chips are 20-pin 0.3" PDIP
  • Register $8000 is at $8000-$BFFF
  • Register $C000 is at $C000-$FFFF
  • ?? is unknown input, tied to GND in all cartridges
  • BF9093 is used in 64 kB / 128 kB / 256 kB NES & 256 kB Famicom singles (iNES Mapper 071 submapper 0)
  • BF9096 is used in NES/Famicom Quattro multicarts (iNES Mapper 232)
  • BF9097 is used in Firehawk (iNES Mapper 071 submapper 1) and in 64 kB Famicom singles (pins 17, 16 are not wired here)
  • CIC stun latches inverse of CPU A0 when writing at $E000-$FFFF
  • Pinout from Kevtris is not accurate
