I love this idea... Easy way to find inputs and outputs. I do know where power and groung comes in. I can test them being driven by the original equipament without much trouble. > chances are some lines are data and one's a clock line, once you find > the clock line you can systematically try different values on the other > input lines and see what happens. a logic pulser might also be nice, > but not essential. The clock line exists only if the display is serial, right ? If parallel I should get something like a /CS line, right ? Thanks a lot for the information. I will find enough time someday to really try this out and put these little creaters to work again.. best regards, Alexandre Guimaraes -- http://www.piclist.com#nomail Going offline?
