Chatgpt (especially deep research) is pretty good about digging up stuff like this

Thanks for that - yes, I haven’t quite gotten on the “just use AI search for everything now” bandwagon, but of course it makes a lot of sense that it’d be in there somewhere.

Guess I’m gonna go to a local service place with this PDF and the TV and see what they can do. I’m filled with anticipation for the day that I can boot up a terminal on Sony’s first TV and include it in one of my exhibits.

I do retro computing exhibits, in case you were wondering why I have all this junk… ;)
