      Correction, there is no native mode on the 64180. That''s a feature on the Hitachi 6309\
      A 6 MHz 64180 is supposed to be twice as fast as a 4 MHz Z80\
      BYTE magazine published a design for a CP/M compatible 64180 system in the Sept/Oct 1985 issues

      The HD64180 was manufactured by Hitachi. Zilog now sells the same thing as the Z180 but with minor differences in the buss signals.

      The 64180/Z180 add a native mode which executes code 20$ faster once enabled, new instructions allow smaller more efficient code, an MMU allows addressing up to 1MB of memory, illegal opcodes are trapped, etc...

The JVC-95 conformed to the maximum graphics specification of the [MSX-2](/museum/msx-2/) standard. However, like the [Pioneer PX-7](/museum/pioneer-palcom-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](/museum/commodore-amiga-1000/) competition. The Amiga already had built-in video superimposition function (GenLock). Eventually it has been sold only in Japan.
