Description

The Pioneer UC-V102, also called O-THE, is a Videodisc controller for "Level 3" interactive systems. It is meant to be used in combination with a Laserdisc Player and the Pioneer SS-D1 video buffer. It was marketed in Japan, Europe and the US. The system is really an MSX2, but without the MSX logo.

Unlike most Hidden MSX systems, getting to MSX-BASIC and running MSX software on it is very easy. If you switch it on, you will not see the MSX boot logo, but you will go straight to the BASIC prompt. Disks and Cartridges can be used just like with any other MSX system.
