Debugging the IEEE-488 bus functions
The bus driver for the IEEE-488 data bus lines was connected directly to the MCU at the old petSD. At the new petSD-duo on the other side, they're connected via a port expander that is attached via SPI to the MCU. The serial transfer over SPI takes of course some time and this broke everything! Had a hard time while debugging but things look good now :)
