Elsewhere in RCA docs, ASCII is already being referred to, with <> listed, but [] or {} not available. Interesting!
And the teletype console seems to have only () and maybe <>? What a mess! I might not get anywhere here.
I was so eager to scan this after it came because it was months before one appeared on eBay!
This is a manual for a popular Compugraphic typesetter, with a very different approach to markup that’s more similar to control characters in e.g. WordStar.
Everything is based on specialized keys, and displayed with special characters, shade, and underline.
Imagine a version of HTML where you’d need a keyboard with a key for each tag!
