    The pattern is fairly easy to understand, just grab an old keyboard,
unassemble it and see how it works ;o) But in MY setup, I used first the
buttombox from Leif (http://w1.132.telia.com/~u13205992/buttonbox/) which
can be reprogrammed from a PC (note: You CAN use it without a keyboard
connected, but I wasn't able to reprogram it thru the puter) and later did
my own design with BASCOM and the optional keyboard lib.

    If you are looking to a simple-no-frills-code to just burn an 90S2313
and use your keys, drop me a mail and I can program it in BASCOM and send
you the hex/source
