Commodore drives can be controlled on Apple II serial!



Apple II and PC have problems sharing disks because one uses
GCR encoding and one uses MFM.  People want to share data
downloaded on a PC with the Apple II.  What to do?  I have been
asking some questions about the Commodore 1571 5.25" floppy
drive on comp.sys.cbm and discovered that it is an intelligent
serial device that can be controlled in ANY computer with the right
driver.  This drive can read and write MFM encoded MS-DOS
disks, besides GCR encoded Commodore disks.

Commodore drives are very plentiful.  They are at least as plentiful
as Apple II 5.25" floppy drives.  They have their own 6502 brain
and RAM.  The computers talk to them using an RS-232 serial
connection and download the files from disk like they would from
a modem.

Can a driver be written for the GS to control these serial MFM disk
drives?  This would make sharing data on 5.25" disks with a PC a
snap.  More importantly, can a ProDOS 8 program be written to
read and write data from a Commodore 1571 disk drive connected
to a Super Serial Card?  Apple IIe and IIc users can then transfer
data from their PC units to their hearts' content.  Disk transfer is
much faster than null-modem or modem transfer, right?

Comp.sys.cbm has several times the traffic of csa2 and hardware
like the 1571 floppy drive, the main drive of the Commodore 128,
looks very plentiful...

If you think I am crazy, you should know that there are two DOS
programs that can run Commodore serial disk drives from PC
COM ports.
