even thinking of designing a new 6809 board for Apple that would be similar in
concept to the PCPI Applicard just as the Mill is similar to the SoftCard. The
new card should run a 68B09 at 2 MHz, have a minimum of 128K of RAM on board,
an MMC card for mass storage and communicate with the Apple bus via a couple
of shared registers.

Since this would be a unique design not compatible with any existing hardware
it only makes sense to start it if it is clear who will write the drivers.
Even before the final hardware implementation is done we can implement such a
system on the Carte Blanche.

Boisy is most definitely the right person to ask about the intricacies of OS-9/NitrOS-9 and 6809/6309 assembly programming. He's forgotten more about it than I'll ever hope to know.

I'd love to see a minimum of 512k on such a card, and it goes without saying that I want one :-).
