With that said it was designed for a technically challenged technican. The tests other than memory are go/no-go tests. They really don't even provide a good description of what the tests do to test functionality. They just provide pass/fail as an output. If you want to trouble shoot based on the failure its tuff when you don't know how the test functions. All in all I find the atari card quite useful but the DiagROM will provide additional abilities which I am planning to try. It will be an advantage to add tests and know exactly what those tests are doing. Believe I'll try a cart version first. If execution can't make it to the cart there's a good chance the code won't be able to hit the serial chip registers either. Looks like a nice tool.
