Description
By storing digitized sound data and options into 27C010 and inserting it onto U3, this MSM9026 board
emulates the function of S1207 chip and its derivatives. The file for 27C010 content should be prepared by
running program 9026pack.exe. The demanded external components are provided on board in specific EAC
(External Application Component) area.
