YEs it does! It requires the components on the floppy drive logic board.
More seriosuly, how do you drive the Ready/ pin on the itneface
conenctor? Can the microcontroller sink enough current? and how do you
gate it with the drive select? If you're doing it i nthe microcontroller,
i can see problems with some controllers that poll the drivses repeatedly
looking for a change of state of the ready/ line.
There is no Application jou can just build out of
a 555 nor there is
one that only uses a micro. So what?
Is that true? I routinely use an 8-pin PIC to develop a READY/
signal from the INDEX/ signal on a floppy drive. Other than +5 for
power supply, it requires no components. I could have done the same thing with a 555 or two, but I'd have to add R and
C to make it work.
Unless you stick a copy of the PCI source code ot every drive chassis, I
know which I'd rather be faced with...
