I've heard rumor that a new generation of CFFA cards is under development.
I believe the old "inCider" magazine had an article on a cool Disk ][ Mod.
It used a bi-color LED that was wired to light up 'green' when reading from a disk,
and it would light up 'red' when writing to a disk. The LED was Red when forward-biases,
and Green when reverse-biased, if I recall correctly.
If the reading and writing were roughly in balance, the LED would glow Yellow due to
the alternating Red and Green colors.
I think this would be much more impressive on a computer's front-panel LED display, but
that's a project for another day.
