Specifications

The HC-30 is a MSX1 with a Z80A from Sharp (LH0080A), a Yamaha YM2220 VDP and a Yamaha S3527 MSX-Engine.

The power supply (9V, + at center) is external.

Yamaha produced a slot expander for the SX-100 called the SX-101 Expansion box (official price: ¥26,800), designed to be placed underneath the monitor. It is compatible with the Victor HC-30.
