I have an MK11 printset, but it has an M8159 schematic which has been superceeded by the M8164 board (which I have). I don't have a schematic for the M8164 board, which I presume is different than the M8159. So, I am looking for scans of the M8164 board schematics... Also, if someone has schematics for the M8728-AC/AF board that would be nice to have as well. --tnx --tom
