A directly connected FDC controller as Dave suggested would certainly be easier.

Easily fast enough for floppy.

Hi

Floppy Disks were a great enhancement to the QL in 1990s with a Trim card and 4 Double Density drives, then the Gold Card and Super Gold card gave access to High Density disks made the QL an excellent computer.

But over 30 years on, a 1.44Mb or 3.2Mb disk has some limitations on size and access.

I mentioned a USB Floppy just an idea on what to connect the Q68 Expansion port.

Maybe a RPI 2W could have WIFI implemented on the Q68, but the Q68 has Ethernet, QL NETwok access to other QL, QXL and QL emulators via QLUB and the Spectrum Next QL Joy2Net adapter.

Much faster as easy to setup than floppy disks.


Regards, Derek
