We're writing a small operating system as part of our OS course, and so far
we've had to read keys from the keyboard, write to the screen, etc...
I decided it'd be neat-o-kool to have the keyboard LEDs working, so I
started playing around with blasting various values into the keyboard data
port. If anyone has a Sun 4 keyboard that uses a z8530 chip, you have to
blast the value 14 into the port, then blast a masked value corresponding to
which LED lit.
People should write better manuals that document this stuff.
