Hardware register addresses

[DAVE_HEMPSTEAD at HP-Andover-om3.om.hp.com]

Hi,
   I've seen software listings fly by which indicate that people understand the 
contents of the hardware registers in out ECM's (for 94,95,96,97 GM ECM's).
   
   I've got the 68HC11 F1 book describing the registers in that chip, located 
from 0x1000 thru 0x105f.  What I'm missing is the hardware registers from 0x1060
through 0x1809.  Can anyone point me to descriptions for these registers?

   I also don't know what the port registers in the MCU are connected to.  I can
try to guess from the software, but, since I haven't traced out the circuit 
board so I don't really know.  Can anyone point me to descriptions of how the 
port registers are used in the 68HC11??

Thanks,
Dave Hempstead
