I seem to vaguely recall reading about RCA or someone marketing a
NAPLPS decoder *chip*. Anybody know anything about this?

I figure that if it *was* done, and wasn't too expensive, it might be
possible to create a board that plugs into the VGA feature connector
and provide *fast* NAPLPS with a simple driver. Since there's a lot
of talk about reviving NAPLPS as a graphics standard, I'd think such
a board would sell if it wasn't too expensive.
