Does it say 1982 anywhere except the pricing table and the submission title here? Is it possible that the brochure is actually newer?

At the very bottom right there is a reference to 0782100M

Googling that returns below which also says (maybe infers?) the brochure is from 1982.

I had considered that, but noticed the price and as classichasclass points out in a reply to me (https://news.ycombinator.com/item?id=43949843), $595 was the intro price. They're also comparing against the Atari 800 instead of the 800XL, so that's another piece of evidence. The 800XL was released in 1983.
