This led to writing a machine code routine to simulate a TV display when no channel is selected-- i.e. "TV Static". Static Demo includes a short BASIC program which starts up things up and lets you choose whether to begin by blanking the screen. StaticDemoDSK.zip is a bootable DOS 3.3 disk image which runs the program. There is a listing of the machine code routine in a Text file on the disk. StaticDemo.shk is a ShrinkIt file with the program files and listing of the machine code routine in a Text file. Rubywand
