I have a Lodge&Shipley Profiturn 40 with the GE1050 control,with the old software tapes.The diagnostic software loads fine and looks like all the boards are ok.However,the executive and MSD tapes dont want to load properly.It might stop loading at any odd spot.According to the manual,the screen should be giving messages,etc.while loading,but nothing comes on,even though the the screen functions properly when I run the diagnostic tape.If I restart the loading of the executive&MSD tape and finally get it all loaded,the"processor error"light comes on,still no display.I havent found a solution for this in the manual,other tha cleaning the reader,etc.Thanks in advance for any advice!!
