Re: Apple IIc external HD

["Jose Ricci" <jricci@entelchile.net>]

Quite a few years back it took me a week or so to write a PRODOS driver and
connect my //c to a PC through a serial cable at 9600 bps. It also had a
clock driver.
It worked well. It is really slow, but it works. My //c can't do 19200
reliably (maybe the cable wasn't well insulated).
I don't have the program now (it vanished with others in an old disk), but
it was a short machine language program I wrote using the PRODOS Technical
Reference Manual and Inside PRODOS books (this one has a terminal program in
assembler from where I took the comm routines). On the PC side I wrote a
simple program in TurboPascal 6.0 (also using an example from a book). It
was made to emulate a 32Mb hard disk.
