Protocol is fairly low level and also pretty extensible in theory so you'd be able to bitbang the DVI end on a microcontroller OK I think, and probably even prototype it with an arduino and some sketches if you just shoved the video out of a serial port to get yourself started. Floppy interfaces make things a lot more complicated though because all of sudden you need power and you are dealing with 5v high current lines and 12v supply plus motor driven spikes in power consumption. Might be easier to just use floppy images on an SD
