The first Victor computers were essentially rebranded Yamaha MSX machines without SFG music module. A superimposing adapter module (HC-A602S) was sold as an option.

The HC-5 is available in two models:

  • first version is the same as the CX5 or YIS-303 but with only 16kB RAM
  • second version is the same as the CX5F or YIS-503 but with only 16kB RAM

This machine was aimed at the Japanese market. The power supply is internal.
