hi all there,
i am really new to the list, so forgive me if the question is silly.
i read the thread, and :
would it be usable to have a 8255 (24 io pins) in the parallel port???
i have studied electrical engineering, and had to do this as a lab project. not
too difficult.
of course the software to drive the pins will be _slightly_ more complex.
or the software U use would not be configureable to support this?
