yeah, i know they're just simple logic chips, but my strength lies in higher 
languages, so i didnt think too much of reworking the design ... at least not

i bought a programmer on ebay (managed to get lucky) but i'd like to get the 
documents you refer to ... i can post them on the linuxdc site under the
