71B Diagnostic ROM image
As part of my recent adventure updating my new FRAM71 to 1MB I spent some time with the diagnostic image checking out my work. When the diagnostics start up they first test the CPU and display the CPU speed and then prompt for a command, pressing the 'H' key will give you a quick list of the tests available. The description of the 'M' key might lead you to think it will do multiple passes but what it actually does is run all the tests in sequence. The 'A' key (Auto) is the one that loops tests, and I am sure that anyone who has played with the diagnostics will have already discovered this. When looping a test with the 'A' key you can halt it by holding the orange 'f' shift key down until the diagnostic cycle completes. The one really new thing that I discovered by accident is the 'C' key, which will display the last error code reported and after exiting a looped diag it also display the number of passes executed.
