Re: Get the ZFDC controller to format a disk...

Hello John,
i notice while testing, that the ZFDCDIAG program subroutines 11 & 12 (R/W tests) only uses one side of the disk.
On the screen the side changed between A & B, but not on the hardware.
The read tests 0E & 0F are working with two sides.
Is there a reason for?
