systems. Very good at DC servos for max acceleration and deceleration with a
gentle touch. Very impressive. RCA stuck with the old AC motor drivers for
everything just about and that made for a very rubbery control of reel servos
and belt drive. On the 1” machines, the ability to grab a reel and move it to
jog the tape by hand. Nice touch. <o:p></o:p></span></p>
