== Technical ==
Connects between Z80 CPU and mainboard. Uses a 1.8432MHz oscillator, MC14411P bit rate generator, a 6850 ACIA, a MAX232 voltage converter, and 74LS04 and 74LS08 logic chips. See CPCI description for details on the 6850 chip. Port addresses, schematics, and differences between versions I-III are unknown (the AMSSIO webpage doesn't exist anymore).
