I have spent the last 6 months working on various new retro products, and now I am finally getting back to updating SuperCard Pro.
I have hired a programmer through FreeLancer to write a virtual floppy driver so that disks inserted into a SuperCard Pro setup will appear as drive A: (or B:) under Windows. This will require an installation of a virtual device driver and updating the SuperCard Pro's firmware.
I am also working on a small open-source Arduino project that will turn a 3 bay DVD duplicator case into a dual drive copy station, which won't need the use of a PC at all. It will be completely portable. The SuperCard Pro hardware itself can be controlled by any device through one of its serial ports. This is something that I have intended to have since the beginning.
Also, the SupeCard Pro has a bi-directional bus setup - so, it could emulate a floppy drive much like Gotek or HxC devices do.
These are all things coming in the near future.
