Description

VHD BASIC is an extension provided by

  • the Victor IF-7510 interface that can connect the MSX1 HC5 computer with a VHD (Video High Density) player
  • the Victor IF-7900 interface that can connect the MSX1 HC-7, HC-6 and HC-60 computers with a VHD (Video High Density) player
  • the Victor IF-C9C interface that can connect the MSX2 HC-90 and HC-95 computers with a VHD (Video High Density) player
  • also the Victor IF-C9D interface, but in a downgraded version for a specific using. It does not implement the CALL VHD interpreter instruction, only the CALL VP instruction. It can be used to play VHD games that have game code on cassette.

Note that the HC5, HC-6 and HC-60 machines need to be extended with the superimposing adaptor module HC-A602S.

Instructions

VHD BASIC adds at least two new instructions. Other instructions are unknown, the ROM containing also the VHD interpreter has not yet been dumped.

Note: CALL can be replaced by the character underscore (_). A space is not required after this character. See CALL for more info.

Instruction Generation Function
CALL VHD MSX1 Starts VHD interpreter
CALL VP MSX1 Gives commands towards VHD player or inquires from VHD player
