would it be possible to ad an USB hub to the card, so you have 4 USB ports on the card?
Maybe 3 external and 1 internal.


Or better yet, do like the RaspberryPi and use a lan9512 USB hub chip that has built in Ethernet!! :)

@Chaoslord the actual hardware limit is 4gigs... The 68k can never see more than that due to the 32 address lines maximum the architecture can support (and most Amigas only had 24 address lines = 16meg limit).

Software can be patched to use larger word sizes... Hardware can't.

@ChaosLord I'm pretty sure Karlos is right here... F0-F2 are flags for memory management, you can't arbitrarily use them as bank selects. The documentation describes their function clearly.

The 040 and 060 doesn't need to flag memory management to the outside world as it has a built in MMU :)
