U0>M1 on the 1571

Date: 2001-10-16 11:44:18

Hi All,

Does anyone know what the 1571 drive does "electrically" when this command
is issued?

From what I can tell (without wiring up a Oscilliscope - which I don't have)
it seems to hold all lines (ATN, CLK and DATA) low whilst it does some sort
of reset of the chips etc (goes to 2MHz etc)... Is this so? and is it the
same regardless of whether the is a disk, no disk, single or double sided
