Im retrofitting my 720 all modern electronics motors with decoders and run with a control center as big as a matchbox ! Fed by my laptop ! So all electric parts , Fanuc motors,transformers switch gear etc , display and screen contoller complete and all cables plugs ,boards etc , tell me what you need and I will try and supply you .It all works ,except one encoder , just started on this journey as it takes for ever to get a specialist to to turn up and he walks through the door and says hello €850 please !! I thought thats it , find it yourself , then I asked my nerd mate and he said rip it all out I will convert it and then we/you can repair it yourself .And by starting this adventure tested an encoder and sure enough oil on the glass !! But no more stupid , lets face it , old kit to play with anymore . So if i can help drop me an E , all the best Harry
