Re: IDE and CF on CFFA

[Rich <***rich@dwave.net***>]

Hi Guys,

I have sucessfully installed and used Glen Bredon's DOS Master awhile 
back. It was a little tricky to get right, but it did work better than
I thought it would.

But what I was thinking about for DOS 3.3 support would be to gut the 
CFFA firmware of all of the prodos specific stuff, and just keep the 
core sector read write routines. Then add the code to interface that 
code to DOS 3.3. The other key would be to rewrite that much simplified 
firmware it so that it worked with the 6502 and therefore the Apple II, 
II+, IIe.

I guess what is stopping me is the time needed to reverse engineer 
DOS3.3 enough, even  given there are good references on the subject. It 
would still suck up a large number of weekends that I don't have right 
now.

If someone has done that already, and actually still remembers anything 
about it, and could lay it out for me, I would be very tempted to jump 
in.
