Anyone Have schematics for the memory boards?? I Have swapped the big ribbon cable 180* and still nothing. I took an eraser to the contacts on the boards to clean them and nothing. I can get it to say load master but it has a funny symbol after master and a small rectangle in the lower right side of crt but it wont load the master.
One thing the last program that was ran was a very long G-code program and then it was shut down and the buffer was not emptied is that anything??
