Magic Sound Board

Revision as of 17:08, 3 February 2010 by Nocash (Talk | contribs) (→‎Pictures)

The MagicSound board from Patisonic is a 4-channel DMA sound expansion for the Aleste 520EX from the same company.

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's using the additional DMA pins on the expansion port, so it works only on the Aleste, not on normal CPCs.
