Why not buffer to an SRAM? The data wouldn't need to remain after power
goes off if you're just using it for a buffer.

On a side note I doubt a floppy interface would be practical at all.
The HP-48 has one and it costs nearly $300, and its just not worth it.
If you want a small portable way to carry around programs, buy an E2.
Floppy drivers require too much power, are too heavy, and are too
hard to interface.
