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: You can think of the OPL4 chip as an OPL3 and a Gravis Ultrasound ducktaped together. And coupled with the YRW801 ROM chip and a software translation layer, the OPL4 can do Wavetable General MIDI. YRW801 Wave ROM Datasheet
