That is my preferred route, though if this turns out to be a later model, they started using surface-mount teeny-tiny components.. Which may scupper me. - Not had a lot of luck with 'recovering' SM components to date.ntpntpntp said:When I chipped my 66, I turned the LEDs round on the mounting pcb and re-wired to make them work common-positive as required by the decoder. I abandoned the main board PIC controller for the lighting and made a new stripboard with resistors etc. to route decoder functions to lights.
