OEP-3 V1 (UC)
2. Ribbon motor drive circuit (Take-up and supply drives)
Motor drive circuits IC609 and IC606 on the SE-539 board are controlled by the control signals at pins 95
and 96 (take-up) and pins 97 and 98 (supply) of IC5 (CPU) on the PRT-13 board. The motor is
accelerated and decelerated proportionally to the reference voltages at pins 20 and 21 of IC11 on the
PRT-13 board.
