Busted Confocal Laser Scanning Microscope Leica TCS 4D Motorola CPU controller

Dear all, Im Riccardo Porceddu and I work for the University of Cagliari in Italy. Im wondering if you are able in helping us for fixing our confocal scanning laser microscope TCS 4D Leica. The problem is relative to the motorola CPU controller. We are interested in any kind of solution, as reprogramming the CPU or buying some part of, or even in replacing some parts with those of a more recent microscope, if you know how to upgrade it, substituting the original motorola CPU. Thank you in advance Best regards RP
