The Pioneer PX-V7 is a MSX1 computer, aimed at the Japanese market. It was meant for attaching to a LaserDisc player, and as such has Superimpose capabilities.

The PX-V7 was available in silver with Lilac keyboard keys.

Help needed
This machine seems to be identical to the PX-7, It is unclear if it was meant for a different market segment, or released later as part of a re-branding exercise. It is however quite a bit more rare than the PX-7. If you have a PX-V7, we would appreciate your assistance to understand what the differences are. It would be especially helpful if you could dump the ROMs so they can be compared to the ones from the PX-7. If your able and willing to assist, please let it be known in the forums.
