Hi all, I'd like to add a third drive, which would be an external 3.5", to my TRS-80 4P. The 4P never came with an external floppy connector like the TRS-80 Model 4, but the 4P floppy controller apparently does support four drives and some folks have successfully modified them to use external drives. Any ideas on how to do this? I'm thinking maybe just set the 3.5" drive select jumper to DS2 (there's DS0, DS1, and DS2)... connect enough straight floppy cable and connectors for everything to the internal controller jack... and see if the 4P recognizes the 3.5" drive as :3. Thanks, Steve P.
