Hi Dave, >I been messing with taking the ALDL into a laptop SOUND RECORDER and >decyphering the WAV format to grab the bits and convert them to >bytes. Interesting concept, just a quick question... How do you send commands to the ALDL? Can you generate .wav files and send them out the sound card, via the headphone/speaker jack and then into the ALDL. Would that work? Just a thought Paul Blackmore
