Museum TV installation

Got the pinout and a minor logic error straightened out. All the buttons work and their respective LEDs light up. Except one LED which seems to be on all the time. Lots of head scratching. It was mounted backwards. These switches are supplied with the LEDs fitted but it's possible to extract them and put them in backwards. So either the switch has always been wrong or some joker at Michael Cox Electronics (these control panels are ex Cox) took the LED out and reversed it to fool some poor test engineer.

Need to sort out the standby input and the testcard/offair switch for when it's in standby.

Also need to check the feed to the router though I haven't yet made the adaptor cable to connect the router to the controller.
