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. The unique 56-pin cartridge slot has 6 special pins named abcdef: a, b and d are shield, c is sound in, e and f are slotselect.
Pins -12V and +12V of the cartridge connectors are not connected.
Yamaha produced a slot expander for the SX-100 called the SX-101 Expansion box (launch price: ¥26,800), designed to be placed underneath the monitor. It is compatible with the Victor HC-30. This one delivers the -/+12V from its slots.
