Baffa-2 MSX PPI / ROM
The PPI (Programmable Peripheral Interface) is a chip used by MSX to select the current peripheral (slots, keyboard and cassette player). The Baffa-2 PPI board also includes the Rom socket which is connected to Slot0.
For the MSX2 project, the Rom IC is ignored as it is necessary to use a subsrom circuit to switch between main ROM and subrom.
