What did hitting ESC do and when is the 'right time' to hit it? I was not aware of this added feature. My IIC+ only has its internal 3.5, an external 3.5, and a floppy emulator. I have not yet been able to emulate 3.5" floppies on the emulator, so it is standing in for the double 5.25 drive I also have. I got the emulator mainly to allow me to sneaker-net 5.25 floppy images to my PC/Linux machine to share.
