The JVC-95 conformed to the maximum graphics specification of the MSX-2 standard. However, like the Pioneer PX-7 it also carried a sophisticated hardware interface that handled video superimposition and various interactive video processing features.

In fact, the case housed two separate electronic cards. One was purely MSX, the second was dedicated to additional video functions. Several programs were bundled with the system, they allowed pictures, graphs ot texts to be mixed with any video source.

Another interesting aspect of the HC-95 hardware was it's double prrocessor feature. User could select between the usual Z80A/3.5 MHz processor and a custom JVC processor called HD64180, running at 6 MHz.

JVC tried to sell its HC-95 in Europe with no success, probably because of the Commodore Amiga competition. The Amiga already had built-in video superimposition function (GenLock). Eventually it has been sold only in Japan.
