OK, here's something:

Jim Rothwell (see the gallery image and enlarge it) was supposed to release something called Ace of Aces for the Ultimax, it seems, IIUC.

I didn't know about the Ultimax until 5 minutes ago.

EDIT: Here's the image link:

I don't know anything about the Ace of Aces pictured, but it's definitely not the Artech/Accolade one. $595 was the 1982 introductory price for the C64, so this pamphlet almost certainly dates from then.

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.
