Only problem is, the AEK will look too new next to that thing...
Put a USB keyboard controller on an Apple //e's keyboard (which uses a key matrix, and even has Open Apple (Command) and Closed Apple (Option) keys,) though. Then it'll look right.
Even if the computer is actually in the floppy drive, not the computer itself.
All that leaves is adapting the Mini's output to composite, but that's not a problem. Hook it up to an Apple Color Composite Monitor for maximum win.
