Probably the most noticeable difference between the System 2 and System 1 games was the fact that the System 2 used higher-resolution graphics. The video resolution was 512x384 and as such a medium-resolution monitor was used (System 1 used low resolution).

The hardware was similar to its predecessor in the fact that it used two main circuit boards. In this case it used a "CPU board" and a "Video Board". The EPROMs were split between both boards.
