Correct reaction of READY signal upon MTR request (DD floppy in drive DF0) and expected rotation speed of 300RPMs (index pulses period 200ms):
Correct reaction of READY signal upon MTR request (HD floppy in drive DF0) and expected rotation speed of 150RPMs (index pulses period 400ms):
Please note that the DF0: in the photo above is indicating "(DS-DD 80)", just because I did not re-check the DriveID's by exiting and entering floppy drive test in ATK.
HD floppy read test:
Proper RPM control for DD (300RPMs) and HD (150RPMs) floppies:
