I have been playing around (well attempting to anyway) with the cassette in
port. Since nothing I do seems to work I wrote a short program to grab values
from the cassette in port and write them to memory. All I get in memory is
$FF's. I have come to the conclusion that somethings broken in the cassette in
circuitry. Does anyone know how I can confirm that my cassette in is broken
and then isolate the broken part so I can replace it. I know by looking at the
schematic what items are involved, I just would rather replace one thing
instead of the whole circuit. I'd appreciate any help that anyone can give
Oh by the way, this is on an unenhanced //e in case it matters.
