===== History and Trivia =====

"KC" stands for "KleinComputer", which could be translated to "Small Computer".

The KC 85/3 was the successor of the KC 85/2. Improvements over the old system were more free RAM for programs (30 Kb instead of 18 Kb), a larger ROM (16 Kb over 4 Kb), which included the Basic interpreter (with the KC85/2, you had to load it from tape).

Both CAOS and Basic interpreter also had some new commands, especially for graphics management but the Basic remains fully compatible with the 85/2 version.
