Emulation Board for S1207 A red LED lamp D3 is provided to indicate the power on or off. A 32-pin textool U3 is provided to store 27C010 EPROM (access time 120 ns or faster). 5 green LED lamps are provided on EAC area. 5 red LED lamps are provided on EAC area. 19 push button switches for triggers are provided on EAC area. A 2x1 jumper header JP4 is provided on EAC area to accept wires to speaker. A 3x1 jumper header JP5 is provided on EAC area to decide source for K1,2,3,4 triggers. A 3x5 jumper header is provided on EAC area to select LED lamps for 5 output pins or not. To be continued on page 3/6. 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 ponents are provided on board in specific EAC (External Application ponent) area.
