CompuPro - System Support 2 Board
The System Support 2 board was essentially an improvement on the CompuPro System Support 1 board.

CompuPro System Support 2

This board provided the system with sophisticated control of bus interrupts, independent interval timers, a "real time" clock/calendar that provides BCD hours/minutes/seconds /month/day/year with battery backup, and full RS-232 serial channels which included full handshaking.
