Not yet. Probably the "cleanest" way to do that is to take advantage of the
user switch in the S3 dip switch; if you connect a push button to the pins
10 and 11 of S3, you will be able to see the pressions by reading a byte
from the PCF8574A mapped at 0x39. In the same byte there are also three
signals named as "spare IO", but they go directly into the CPLD and I
haven't checked if/how they are handled.

Cheers, Lorenzo
