Is there a site or file or some such that someone can use to diagnose problems in a apple II or Plus, E, etc?
Some sort of thing that you check this thing first them goto here if this or there if that? Something kind of modern. not someting from Apple that might say 'replace main booard' if this fault occurs.
A toubleshoting guide? Something a non EE person can follow with a good general knowledge of computers, ie a long time hobbiest? For some one that dose not know what video sync is, or how to test a crystal, does not know a O-scope, just a multimeter and a soldering iron.
