Thanks for the notification Matteo.
A question, does the MSX Palcom LD is a standard (like the standard '3DO' for instance)? Or is it a *standalone* system?
The Palcom system was a MSX computer released by Pioneer in the 80s. It was a MSX 1 compatible computer with some add ons by Pioneer to allow interfacing with a laserdisc player. It had a genlock and a serial custom port dedicated to the communication with the LDP, with extra MSX commands to access to laserdisc software. More on this system can be found

What is the difference with this 'system' for example?
The system in this picture in the Pioneer LaserActive system, released as home system in the first part of 90s. This is more of a console style platform rather than a computer. It had a slot in which you could put a so called "pack" to enable interactivity, otherwise it was just a standard NTSC laserdisc player (the CLD-A100 model). Depending on the pack, it could become a Sega Genesis or a NEC Turbografx, with full CD-ROM and LD support. It could also be controlled by an external computer or become a karaoke system with two more different packs. This has nothing to do with the Palcom system. More on this can be found
