I was always
puzzled about the choice (once I knew what a T11 was). Other
than that, it's a 6502 and POKEY and "other stuff" on boards of that
generation, which you would expect from Atari, but not a T11.
Hmm... Atari commonly used the 6502 as the "main" processor, then
other devices for things like the "math box" (2901-based 16-bit vector
engine) for Battlezone, Star Wars, etc., so what's the T-11 doing in
Paperboy?
Communications and I/O (via POKEY), mostly. The T11 was doing the heavy
lifting and the 6502 handled grunt work. It may have also had a role in
sound (again via POKEY) but it's been a while since I looked at how it was
laid out.
Memory is
coming back about other games -- 720 and Super Sprint were others.
This was before they went to the 68K for Xybots, Gauntlet, etc.
That's more than I would have guessed. Sounds like there was a window
in which the T-11 made more sense than the 68000, but that it was a
short window.
Relatively short, I would say no more than two or three years. Still, a
number of well-known titles used it. I don't know of any other manufacturer
that used any PDP-11 architecture in any other game other than Atari Games,
however.
