Memory test fails

Postby John Ferguson » Sun Oct 22, 2017 10:47 am

My Atom appears to be working normally but on running the memory testing programme from Atomic Theory and Practice handbook every address chosen reports an error.

The graphic modes clear 1 to 4 show no sign of the any faults so I am puzzled as to the conclusion I should draw from the test.

Please could I receive comments and suggestions for any action I should take if any.

John, are you sure that the program is correct, no typing errors?
