Model I machine language cassette programs will run just fine on the Model III given that the restrictions on direct hardware access mentioned are respected. For example, for my game RoundUp!, you can load the 500 baud tape version on the Model I or Model III just fine. Of course, you need to specify “L” for low rate baud of 500 at the Model III Cassette? prompt. The model I only supports 500 baud cassettes.
