Wanted: null modem serial cable for Apple //c

["John J. Boia" <fourbears@tidalwave.net>]

I'm planning to resurrect my old Apple //c and
use Apple Disk Transfer (ADT) to use my old
software with an emulator on my PC.  Does anyone
know who makes a reliable, inexpensive null modem
serial cable (DIN5M to DB9F) that suits my needs?
Also, any tips on doing the disk image transfers?
I've read about the //c serial port problem (mine
is one of the oldest //c's).  Any advice would be
appreciated.
