Andy made a demonstration video about the BeebSID. The BeebSID is a project from Martin Barr and Tom Walker. They made a circuit board with a SID chip, that connects to the bus of a BBC Micro computer. With the BeebSID you can play SID music on a BBC Micro computer. You can also see a HcX floppy disk emulator that is used to load the SID data.
