I'll change to use POSTINC0 rather than INDF0.

After that change, I'm still reading all zeros.

I have the 1302 datasheet printed out as well as my code. Time to make 
sure they 'agree'.

BTW, I did check the hardware connections, and all the ports are set 
correctly and wired correctly to the 1302.

The carry bit does not matter, as only the 8 bits in the byte are 
evaluated as they RR and reach bit 0.

Again, I don't think the carry flag would matter, as only the 8 bits of 
the byte are transferred to the B0-B6 location.
