Others have made their guesses about what you want to do. I will make
mine.

I replaced the prom in a super serial card so that it is recognized
as a disk drive and includes code that passes all block read/write
commands through the serial port. I wrote an application on a Mac
that maintains one or more files as Prodos volumes and responds to
unit/read/write requests over the serial port. I can boot an Apple II+
from the Mac, read/write files, and everthing else you do with a
hard disk except at 19.2 kbps. Is this what you want to do?

I wrote the Mac part to give me a way to back up the hard drive on
my IIe. I fiddled with the serial card stuff as an experiment. The
II+ doesn't have a hard and I wanted to see how booting from a mac
would work. This has been abandoned for other projects but the pieces
all exist.
