Casio E15 gpio definition (2002/03/18)
======================================
This document is the result of my investigations
about Casio Cassiopeia hardware definitions.
Feel free to append any informations about E15 that
you think useful.
François Leblanc <fra...@ce...>
This informations are no officials since Casio cie
never transmit me any informations of this device
although I ask them many times.
<<I advice anybody to not buy casio devices for future
use unless they don't need linux on it. Casio don't
care of open source developpers and don't give any
informations of any kinds about theirs products. I
had to spend a lot of my time life to get this
informations available althought device is quite
old... I don't think that device schematics are
still secret, perhaps they use it on nuclear weapons? :-).>>
Sorry, it's for my nerves because they get on my nerves...
due to this I prefer add below:
