  • PRG RAM: None
  • CHR capacity: 8 KB RAM
  • CHR bank size: Not bankswitched
  • Nametable mirroring: Solder pads select vertical or horizontal mirroring
  • Subject to bus conflicts: Yes

Banks

  • CPU $8000-$BFFF: 16 KB switchable PRG ROM bank
  • CPU $C000-$FFFF: 16 KB PRG ROM bank, fixed to the last bank
