PS. TO OUR CO SUNDAY NIGHT:
The coin-op Star Wars used a 6809, along with a bit of TTL widgetry to do fast
math for the 3d vectors. From Star Wars on, Atari coin-op switched from 6502 to
6809. The Atari 400 and 800 were originally designed with 6809's but Moto
couldn't deliver on time, at least that's the scuttlebutt. Williams electronics
used 6809 from their first game (Defender). Most Japanese designed games e.g.
Pac Man were Z-80 based. Interesting to note that coin-op hardware designers
pushed the technology to the limit, no other micro applications at the time
came close to the complexity or innovation of a typical video game. Some of
them are fun to hack on. For example, QIX, by Taito America, has dual 6809's, a
6800 for sound, 64k of video ram, and, get this, a standard db-25 rs-232 port
for your terminal or host computer.
