Thanks to my friends for cluing me in. Apparently I don't know how github works or how Web search works (anymore). But I got no online help on searching about this thing. It's tedious to explain how I don't know something, this amounts to "proving a negative" by showing where something is NOT. But the developer did not leave a "signature", which boggles my mind. I made an effort. The link given to me in this thread, led to the result (demonstration) and not the project (source) page - I must not know how to change "grantmestrength.github.io/S100/" to "github.com/GrantMeStrength". Other references that search found to this product, also were a single link to a demonstration and nothing more. No mention of a person. Github, by the way, has changed a lot since Microsoft bought it a few years ago. I don't have content on github myself, I browse content from there, so I don't keep up with recent ways to use it, as in github.io vs github.com. When I've tried to search github.com on-site, it "chokes" and tells me it thinks I'm scraping content (like an AI would). I am less than happy about using github. The S-100 Google group has no local-search responses to "givemestrength". But when I search for "kennedy", I find a recent post by John T Kennedy of May 9th which has the link to the working emulator (which includes the string givemestrength). That says something lacking in Google group searching. I also find quite some history of Kennedy's posts in the Google group (when searching by his name), so that confirms Geff's response. I'm not very active in that Google group, that's not a negative for it from me. I know something about S-100, I have a Web presence about S-100 that's been findable. But I'm not an active participant in every discussion group about S-100 things. I can imagine people with less experiences than mine, maybe some with more experience, may also have some difficulty in finding out anything about the origins of this bit of code. I can also imagine github developers rolling their eyes at my situation. I have a point. All this may have been avoided, if Mr. Kennedy had included some reference to his github source page in his browser-based github demonstrator. There was no "help-me", no "about", no active click-on link, no signature with his name or github-source link. The oldest programs I know of, have some creation information associated with them. I don't know the lessons learned here. I think it will be easy for people to dismiss my ignorance based on my age or disposition or limitations. But I did some plausible things and got no responses; so I assumed there was nothing to respond to. Who would create content but not put their name on it? Not leave a clear trail? "Clear" depends on your experiences, my experiences are ultimately limited by my age. That's a lesson. Regards Herb Johnson
