How many use old browsers (e.g. =< Netscape 4 or IE 6) as their ONLY source of web content?

Thanks for all those replies, and feedback on what the test page looked like on various devices. Much appreciated. I see there are various views as expected. I guess it depends on what I want the website to do in the end. One of the reasons I'm doing this is more to make sure the pages are ok for mobile. A lot of people now use a mobile platform for their leisure browsing. On average 25% of the people looking at the site are now on a mobile platform. However, I also want it to be nicely formatted, although somewhat minimalist and clean. I also want it to be easy to maintain. I'm not interested in people seeing ads (if fact those google ads on the site at the moment are going to disappear) or whiz-bang things. I'd like to think the site might inspire people into the hobby, or get them interested in the history of personal computing, somehow. Especially younger people, or people in their 30s-40s who weren't necessarily there in the day,,,or were very young. This is why I'd like google search to index them well. So people can find them. The site doesn't offer a lot of resources in the sense of downloads to the community..the exception being the System 80 sub-section and NZ Bits and Bytes downloads (which is mirrored on achive.org anyway). At the moment the System 80 site might stay as is. It's a complex site and will probably be the last piece I tackle. Bill, can you point me to a site which covers this? What I don't want to do though is to duplicate the site, but if something can strip out everything except text, images and links on the fly if it detects a non-compliant (old) browser, it might be worth looking at. Yes. It's an "is the effort worth it" for those hardy few kind of question. Terry (Tez)
