Thanks for the pointers and the sentiments. Will need to get a disk emulator to move forward. I am locked in 1980's hardware at this point. I have a //e, 2x //c, and a IIgs.
Nice. ADTPro with the IIc works great (easy to make a serial cable, just need floppies) - but they're also great emulators now, Floppy Emu, Fujinet, wDrive...
