Finally, I recall seeing an article where
somebody took a pocket
calculator chip and essentially poked simulated keystrokes at it and
then decoded the LED driver output to determine the answer. It was very
slow, though, so all it saved was the space of the floating point
library code.
I remember that one. It may have been an early issue of Byte. I
also wondered at the time if any speed was gained over just running
plain old x80 code.
