AMSDAP - CPC and MSX expansion slots for Amstrad CPC

The AMSDAP is developed in collaboration by Prodatron and TMTLOGIC.

With this board, it is possible to use MSX hardware on the CPC computer. This only applies to hardware that uses the IO bus of the Z80. Hardware that uses memory functions is not supported.

On the board is a DC / DC converter that provides the +/- 12v of the MSX. The maximum current is 84mA.

Technical information

The address range of the MSX can be found at &FFxx

MSX hardware supported

SymbOS makes use of:

• the graphics cards based on the Yamaha V9990 graphics chip V9990 Datasheet V9990 Application Manual
• the MP3 hardware player soundcards MP3 Player Specification VS1011 Datasheet
• the soundcards based on the Yamaha OPL4 sound chip OPL4 Datasheet OPL4 Application Manual DAC Datasheet

Note: The OPL4 chip combines an FM synthesizer (same as OPL3) and a Wavetable synthesizer (like the Gravis Ultrasound). Paired with the YRW801 ROM chip and a software translation layer, the OPL4 can do Wavetable General MIDI. YRW801 Wave ROM Datasheet
