This is how the retro computer community does it. Instead of trying to keep an aging 30-40 year old floppy or hard drive working, people make all kinds of interface adapters to convert it to be able to use SD and Compact Flash cards. It's usually something like an AVR or PIC microcontroller that talks to the ancient computer on one end, and interfaces with the newer storage medium on the other, acting as a middleman.
I have a NES cart that does this with ROM files on an external card. As long as you make it speak the old protocol, you'll fool the machine into thinking it's using the same old equipment.
It's hilarious when some of these old machines install OSes like Windows 3.11 in like two seconds with a solid state upgrade.
We had one of those SNES adapter devices that would let you rip a rom from a SNES cartridge onto a floppy disk and use that to boot the game. Worked great with rentals. I wish she wouldn't have sold it when I was still young because those things were not that common (and super illegal in a lot of countries).
CF cards use the IDE protocol, just in a smaller form factor. Slap one of those bad boys in an ancient PC, and it absolutely flies!
Someone found an old 486 at work somewhere and put it in the junk pile. I pulled it out and did that swap after I accidentally killed the hard drive. It ran like the blazes. It was a little tricky to figure out how to set the CHS values in the BIOS.
Oh snap that's so geeky cool!
