Some notes I once wrote in a CoCo forum have been conserved here: http://www.cocopedia.com/wiki/index.php/PAL_Coco_Differences As you can see, I couldn't remember the UK vs. Australian VHF channel numbers well. For sure the Netherlands version of the CoCo 1-2B didn't have a channel switch at all (RF modulator output fixed to UHF channel 36)
