CyberMaster was a small subtheme of LEGO TECHNIC. It was seen in 1998, and came with an RF operated programmable brick giving it better range and less directional issues than the IR based RCX. The sets came with a unique technic figure - part cyborg. The lead set of the theme, the 8482/8483 Cybermaster set came with a PC CD-ROM with the software to program the brick and communicate via the included RF tower which connected to a PC's serial port. The CD had games and instructions for the set.
