That "splains" it then. Thanks!

Ah, yes, in each of my tests, the unpowered drive
was set for
DS2 (drive B) and TM (termination) and was at the end of the
cable. But, I thought that the termination was to ground?
termination is 150 ohms (for 5.25" floppy drives) to +5vdc... one
of the reasons that one drive only can be terminated otherwise
the output drives can't handle the current and if there is no
termination then there is not a valid logic high level.
