PData is an utility for transfering both binary and text files between
the C64/C128 and Amiga, employing a high-speed parallel cable. It's
about 25 times faster than a null modem cable -- the maximum rate in a
standard, non-expanded C64 is 2.4Kbps. Best of all, it leaves your
Amiga's serial port free for other applications; yes, this means that
while you're porting software over to the C64, you can download more! :)
Oh, and did I mention - PData's freeware, too!
