An article by Allan Myers entitled 'What is a Crest & Seal Chip?' (first published 1999) has been added to my website. Link is near the bottom of the index page. This part of my site will soon be altered to provide a page per author as the good Doctor (for one) has more to offer!
Many thanks for your contribution Allan
