Unexpected floppy behavior...

[Steve Thatcher]

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.

best regards, Steve Thatcher

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?
