R > ROBOTRON > KC 87   

KC 87

The KC87 is the successor of the KC85/1. The main difference between the two systems is the built-in BASIC interpreter. Thus it was software and hardware compatible to its predecessor.

This model existed in two different versions: KC87.30 and KC87.31. Latter had the RGB option already included.
