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.
Chicklet keyboard, QWERTZ-Layout, 64 keys. 6 function keys (F1-F6), cursor keys. Keyboard connected to the UC through a mono audio-jack.
