I don't know if this is on your list, but I know for a fact that the Nintendo 64 system (or N64) has a 64-bit architecture.
Explanation:
To move substances against a concentration or electrochemical gradient, the cell must utilize energy in the form of ATP during active transport. Primary active transport, which is directly dependent on ATP, moves ions across a membrane and creates a difference in charge across that membrane.
