Poster: beattidp Subject: Re: WD1793 Floppy Disk Controller I want to read all my 5-inch floppies, using Sprinter. These were created on TRS-80 Model 4, and have 256-byte sectors. What is the I/O port address for 1793, and what is I/O port address for "drive-select" for A and B drives? (I wish to use a 5-inch diskette for drive B). How is interrupt provided to the CPU from WD1793 (e.g. NMI or other INT)?
