Are you sure. Link232 works fine without the 7474
(http://www.jbrain.com/vicug/gallery/hs232). If needed, one IC is easy
to add, but the 6551 works fine without it, as far as I know.

I don't have any of those, but I do have a CMD HD, so if no one has a
CMD HD and can test, let me know and I'll see what I can do.

No worries. My day job includes thinking about all of this stuff; I
just don't have the time to implement it all.

Just thinking about ways to keep as much of CBM DOS intact (layout as
well), but offer larger disk sizes.

I don't know enough about it to state whether it is harder or simpler.
FAT is simple, yes, but LFN support and other features make it kludgy.
Still, the closer you can keep the FS to CBM specs, I think the better.
