Today we'll look at TEDMON, which is a machine language monitor built into the Commodore Plus/4. But it has almost everything in common with monitors from throughout the Commodore 8-bit family, from SuperMon on the PET, to the Commodore 128's built-in monitor, to the machine code monitors in the Commodore 64's Action Replay and Super Snapshot. We'll go through every single command with examples of how they can be used, along with some insights into the relatively rare Plus/4. This video is made in conjunction with retroCombs' video series walking through the entire Plus/4 manual, check out the playlist link in the video description.
