Apple //gs ROM 03 burn-in mode



I don't know if this is documented or not but I discovered while examining the diagnostic source code that if you press ctrl-oa-ca-reset to run the diagnostics then hold down the oa and ca keys it will do a continuous burn-in loop through diagnostics !!! There is a debug mode that can be enabled too involving port $C046 with some kind of jumper/connector but cannot reproduce that yet especially in emulation. The debug mode enables software control of the diagnostics.
