I still look at games like Twilight Zone, Indy Jones Widebody and think they did a hellof a job with the techology they were working with in the earlier times..alot of innovation and special care went into that era...still makes me proud when i look at most dmd machines from that time....just a whole lotta fun stuck on 4 x silver or black legs really !

Its still the same technology Cavey. The technology at the time was very common place... we werent in the dark ages. Problem is that the games you mention are still the same as the games churned out now. DMD was new at the time and was an innovation... its no longer an innovation, it is in fact a poor way to display graphics in todays market.
As for the game itself.. coils, micro switches etc, this has hardly changed in 100 years.. the micro replaced the leaf switch, optos negated the need for a protruding switch etc.
Hardly anything has changed since IJ and TZ
