simplified CIA and substitute for the WD1770/WD1772, but with a
different programming model... *grmph*

This resulted in the 1571 equivalent inside of the 128DCR ("1571CR")
being almost completely incompatible with the 1571, because almost all
locations in the area $8000-$BFFF are different.

Whoever came out with this should have been fired...  or promoted, it
Commodore really wanted to make it cheaper. ;(

Regards,
Spiro.
