Your CFFA3000 version might be slightly larger than 50 bytes. ;-)  You 
can review the Apple /// driver for the API calls required to 
interrogate the card's configuration of Smartport devices.  Of course 
you can't take anything for granted like 32meg-ness, and you probably 
want to respond to disk switched error codes (not sure if ProDOS 
inherited those from SOS or not...).

Here's the project page:
