Well, I've got technical documentation on ProDOS (the ProDOS Technical
Reference Manual from about '84), I haven't gotten ahold of any technical
docs on the FocusDrive. I sent Mr. Diaz two emails over the past ~2 weeks,
but have not gotten a reply. In the mean time, I've been disassembling the
ROM on the FocusDrive and trying to figure out how it works.

So at this point, everything is going to be done via ProDOS.

I haven't gotten to that stage of development yet. I've read up on it, and
there's overhead involved. I'll need to do further research to find out if
that's acceptable or not.

Yes, that's the plan.
