Wow, nice project and the MP3s on the site are fantastic! – “SIDman is a portable SID music playing device. If you don’t know what SID music is, then get thee to here now. The SIDman was an experiment to see if a PIC microcontroller could emulate another processor in real time, and still carry out other functions. It seems to have been a success :-). There are still a couple rough edges here and there, but it seems to handle most tunes fine.” Thanks Johan! Link.
