Technological Arts' Adapt812 is a modular implementation of the 68HC812A4, in single-
chip mode, which includes all essential support circuitry for the microcontroller. A well
designed connector scheme groups the dedicated I/O lines on one standard 50-pin con-
nector, while routing the dual-purpose I/O lines to a second 50-pin connector, to form the
address and data bus for use in expanded memory modes.
