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.
That same PIC could potentially serve as a timer with a period in
centuries without any external components--something an 555 could not
do.
