Carte Blanche II has a comprehensive 5V bus interface that is capable of accommodating both data and clocking services.
The bus interface supports both 3.3V and 5V bidirectional logic and has a single bus isolation control bit that can put the bus into a tri-state. Power to the interface consists of +5V, -5V, +12V and -12V.

Adaptors are available for changing the physical interface, allowing CBII to be used in other platforms.
The CBII Commodore C64 to Apple II adaptor board allows CBII to interface with C64 computers. The CBIIC64 adaptor board plugs into the C64's 44 pin expansion port and provides a 50 pin port for CBII to plug into.
