  • The Semi-Virtual Disk — a project you can buy or build yourself, that plugs into a standard floppy socket… to your computer it looks just like a floppy disk, but all the data is stored in RAM onboard!  So then you can plug the same device into another computer of an entirely different variety and read/write the data.  I haven’t tested one but it sounds pretty amazing.
