#98008 - does not make it current Responding to: ???'s previous message |
if you look at the code, the interface to the 8255 is bit bashed - not connected via the bus as such. So, the 8255 should work.
Ok, making the kludge even more kludged may, of course kludge it to work ndoes that make it not a kludge? notice the heading of my earlier response! You couldn't help yourself! Not an attempt to help myself, but an attempt to help the OP avoid living in antiquity. Erik |
