AMSDAP - CPC and MSX expansion slots for Amstrad CPC
[[File:AMSDAP42 TOP.jpg|600px]] [[File:AMSDAP setup.png|600px]]
The AMSDAP is developed in collaboration by [[Prodatron]] and TMTLOGIC.
The MSX ports #00-#ff are maped to:
* CPC: #FFxx. This makes the AMSDAP incompatible with the [[Amdrum]] expansion
* PCW: #xxB0
* Enterprise: #xx (not remaped)

NotesThe [[SID]] sound chip of the PlaySoniq soundcard is accessible on the CPC with AMSDAP (MSX ports #2A for register select and #2B to write data).
