Post by thread:16C64 Conversion Problems

I'm trying to convert the Parallax "Table" program from a '54 to a '64; primarily because I am going to use it as a basis for a controller that needs a 2.5 digit display (as well as a handful of other I/O; I have two of the 33 I/O lines left unused...) The (current) problem is that the '64 does not support the mov !RA,#<literal> instruction. I appear to have gotten around it by using indirect addressing, is there a more elegant way to address the registers above 80h?
