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.
