diarmaid,
HobbyCNC used to use the Sanken/Allegro SLA7062M 21 pin driver chips in their original 4AUPC kits. Checking up on your pin count, I just went to their website to investigate the HobbyCNC Pro kits and your right, the new chips that they are using are 23 pins.
Can you post the information printed on the new chips so we can tell what they are or is the information sanded off like in the pictures posted on their website? It's nice to have that information so that another (hopefully local) source can be found for the chips in case the chip packaging isn't sufficient to contain the magic smoke that makes them work.
