!? It's a Rockwell 65C102 and I'm referring to a Rockwell datasheet... 
but this addressing mode is not present?!? How does one tell, looking at 
the IC (number? revision code?) what it doesn't support relative the 
datasheet?

Would it support RMBx, SMBx, BBRx, BBSx?

Gah! Okay, I'd better fix that. :-)


Thanks for your help.

Best wishes,

Rick.
