For some time now I have been trying to come up with the Port codes to
read/write sectors on my TRS-80 Model III.  The ports are X'F0-X'F4 if I'm
not mistaken, but I don't know what code I have to send to get a read/write.
I know how to turn the drive motor on and I have written a program that tells
me what track and sector the drive is working with by patching into the
keyboard routine.  Any help is greatly appreciated.
