: 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.

I just tried it in the setup I have that it works in,
and although it tries to boot, it says:
"Unable To Load ProDOS".

: 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.

Yes, I remembered seeing that, but that won't matter unless
you are trying to boot it in a II or II+. Even the IIe with
the 6502 can boot a SMARTPORT device, no?
