Hi Cyrille,
Thanks for info abt common line = ground. As you mentioned each of the annunciators symbols is connected to one pin of the YORKE/lcd display ... for determination if port of YORKE or display is fault, is the knowledge of the appropriate pins of the YORKE/lcd display helpful - with a scope it can be checked - its for sure easier than toggling the bits (0010B/0010Ch) with an assemblerprogram - anyway, lets hope that there is anyone in the community, who knows that ?
