Magic Sound Board
From CPCWiki - THE Amstrad CPC encyclopedia!
The MagicSound board from Patisonic is a sound expansion for the Aleste 520EX.
The Aleste 520EX is a rare CPC clone with 512Kbyte RAM, its expansion port includes some additional pins allowing external hardware to access the 512K RAM via DMA.
The MagicSound board is probably even rarer. It is using the additional DMA pins on the Aleste expansion port, so it works only on the Aleste, not on normal CPCs.
