I wonder if there are any Commodore people out here who could tell me what practical differences would result from using a Gotek-type flash-memory-based floppy emulator in place of the C1581's mechanism, vs. using Jim Brain's uIEC-SD or similar. I don't know if the thing would even work in a 1581 case, or if Commodore DOS or JiffyDOS would work with it; but if so, I wonder if the DOS would work slightly more like the real thing, because it would be actual C=/JiffyDOS running on an actual 6502, instead of something new running on a microcontroller. I understand that you wouldn't get any of the directory-changing commands et al. from the SD2IEC firmware. -- Eric Christopherson
