MITS - 88-VI/RTC
Vector Interrupt/Real Time Clock Board
This is the best picture of this
relatively rare board I could locate.
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
