Pin4 & Pin5: Y-Axis S/D
Pin6 & Pin7: Z-Axis S/D
Pin8 & Pin9: A-Axis S/D
Pin14 & Pin16: B-Axis S/D (Slaved, in software, to Y)
Then you have pin1 and pin17, which are outputs as well, available for whatever you like.
However, looking at the UBOB it seems that it only provides 8 "high speed" outputs and that its 'port-stretch feature' inhibits you from using the other outputs as step & direction signals for your fifth drive.... :-( You might want to check with CandCNC though!
