At the dawn of home computing, schools at all levels scrambled to give their students access to this new cheaper technology. The size of such a market was enormous, and so Commodore marketing did what they could to take advantage of this demand, at the cost of their competitors. One such tactic was their "Buy 3 (or 2?) PETs, get 1 Free" promotion. When taken advantage of, the "free" PET might be one of these: the Teacher's PET.

As this promotion spanned the transition from the original chiclet-keyboard 2001-8 to the full keyboard 2001-8N models, it is possible to find "Teacher's PET"s in both varieties. This would also include variation in the screen color. While most 2001-8 models had the white phosphor screens, this one has the green screen more popular in later varieties.
