The 6502 is now a 30Mhz RISC chip???  I assume you mean Mhz not mhz.
I think the previous argument still applies here.  The 30Mhz RISC is on the
24bit graphics board correct?  What difference does it make if the operations
are in hardware or software, they are basically the same functions?

The above are my opinions, which NCR doesn't really care about anyway!
