Raspberry Pi Virtual Floppy for ISA (PC XT/AT) Computers

I was tired of carrying media back and forth to my homebuilt XT computer, so I used dual-ported RAM to build a virtual floppy replacement that serves floppy images up from a raspberry pi. A small BIOS extension loaded into the dual-ported RAM simulates a floppy disk drive. Requests are made by the ISA PC, and served by the raspberry pi.
