The Tech-Index was revised many years ago. It was re-named "Technical-Articles-List" and hugely expanded.
You will be automatically re-directed in 12 seconds to Snowbum's HomePage, from where you can scan WAY downwards & click for the very extensive Technical-Articles-List page.
You also might just be interested in seeing what is on that page, before clicking for the new Technical-Articles-List.
