I'm wondering if it can be done in software with a new keyboard driver.  
I believe the physical interface is just one of the UARTs built into the 
main board.  I don't remember if it's the one in the 68070 itself or the 
68901.  But without looking into it too deeply, it would appear that 
re-writing the keyboard driver would be sufficient to work with AT-type 
scancodes.  Or am I missing something?
