Appears all logic boards are good and passes initial bootup self-test. But when do some DOS command to drives (HEADER command, for example) the motor of R/W head are not move forward. Appears looks like move but don't rotate properly. Appears something wrong about steppermotor sequence? Thanks for advance I have an 8050 dual disk drive for CBM 8032SK.
