and a selection of these is presented below. Click the cassette icons next to each screenshot to download the program files.
Click images bordered in white to see detailed program information about those programs.
Unless specified otherwise, configuration switch 1 should be on, switches 2, 3 and 4 should be off, switch 6 should be on, and the state of switch 5 is not important.
