attiny 85, any pointers?/

Using Arduino Microcontrollers
57

Right, right. Wait, since I manually commented it out and forced the pin definitions to be for the 84, wouldn't it work already?
I changed

#if defined( __AVR_ATtinyX4__ )
const static uint8_t SS   = PA7;
const static uint8_t MOSI = PA5;
const static uint8_t MISO = PA6;
const static uint8_t SCK  = PA4;
#endif

To:

//#if defined( __AVR_ATtinyX4__ )
const static uint8_t SS   = PA7;
const static uint8_t MOSI = PA5;
const static uint8_t MISO = PA6;
const static uint8_t SCK  = PA4;
//#endif

So the pins are definitely correct, I think.
