I have no idea what the Clock Mod. is, and the only useful pod there is the Z80, it is worth $100+US...if working...

The Clock Module is used for signature analysis. It has Start, Stop, Clock, Enable and Ground lines on it. I'm not sure that it can be used on the 9010 though, I'll have to check my documentation tonight. I have one on my 9100 and it goes to a dedicated connector which I don't remember seeing on the 9010. -Chris
