MITS - 88-VI/RTC
Vector Interrupt/Real Time Clock Board
This is the best picture of this
relatively rare board I could locate. If you have a better one and would
like to share it please let me know.
The clock was really primitive.
The board was really a priority interrupt controller the clock/time function was
obtained either from the S-100 bus 2MHz signal (pin 49) or the 60HZ from the
power line. Time date etc had to be calculated in hardware.
The manual for this board can be
obtained here.
