Bill,

Indeed you would need to change the card's signature bytes just slightly
if you wanted the CFFA card to boot in the ][+. The ][+ ROM
looks for: xx, $20, xx, $00, xx, $03, xx $3c which is the sig
that a disk ][ controller has. In the //e ROM it only checks the
first 3 values instead of 4, for this so other controller card can
boot too.

If you look in the CFFA firmware source, if you set the SMARTPORT lable 
to false, it will change the last byte in the CFFA sig from a $00 to a 
$3C to look like a disk ][ to the apple ROM slot scan routine.
