Dosius,

I was thinking, if you ever want to add just one more card into [N]Dapple, 
you might be able to combine the softcard and the mouse card into one slot.

Since the softcard contains no ROM, and is activated by a write to Cx00 
space of the slot the card is in, and because CP/M detects the card by 
simply writing to every Cx00 space until the Z80 starts, you can probably 
just look for writes to any slot, no matter what ROM it contains.

I'm not aware of any other cards that use the Cx00 (not counting C800 space) 
for I/O, and I'm sure the mouse card doesn't.

Be worth a try if you ever wanted to emulate a smartport in slot 5, so that 
you can have direct access to a 1.44 MB ProDOS-formatted floppy.
