For a uC based solution I'd suggest probably a PIC or AVR and some
industrial flash chips soldered on the board or a consumer grade flash
slot, like MMC/SD/CF.
Since we're not addressing the flash directly, consumer grade flash is
probably the way to go.
A simple cheap serial flash reader/writer would be useful to a lot of
vintage hardware users as permanent storage.
