Hello,
I recently installed an emulator 3.5 "floppy on my VFX-SD. The original drive is still operational. As VFX-SD can not handle two drives, you must install an inverter switch on the cloth (wire order No. 10 (check)) to select either the original drive or the emulator.
Emulator is installed HxC2001 Rev C. All works very well. I made some pictures, but I do not know how to send them. If you are interested, please let me know.
Best regards.
