Remove the DSP according to the following procedures. 1. Prepare isopropyl alcohol and a flat IC desoldering machine (Spot Heater HS-600). 2. Apply plenty of the alcohol to the adhesive tape from the reverse side of the main PCB. (Fig. 1) There is a hole on the PCB just under the LSI, and the adhesive tape can be seen through the hole. 3. Leave it more than one minute so that the alcohol weaken adhesive power fully. 4. Using a proper size of nozzle, apply heat to leads of the LSI with the desoldering machine. 5. Grasp the LSI with tweezers, and using gentle force vibrate the tweezers to feel melting solder. (Fig.2) 6. Remove the LSI after meltingsolder at every leads wholly.

The CPU then initializes its internal circuit and clears data in the working strage RAM. Power ON reset When the power switch is pressed, the CPU receives a low pulse of POWER signal. The CPU first raises APO signal to +5V to generat DVDD voltage, then raises RESET signal to +5V. During this period the gate array, the DSP and the key touch LSI initializes their internal circuit. CPU (HD6433298A18P) The 16-bit CPU contains a 32k-bit ROM, a 1k-bit RAM, seven 8-bit I/O ports, an A/D convertor and serial interfaces. The CPU accesses to the working strage RAM, the DSP and the key touch LSI. The CPU also controls buttons, LEDs, bender input and MIDI input/output.

Controlled by APO) (Button scan / LED drive signal) Digital Signal Processor (HG51A115A01FD) Upon receipt of note numbers and their velocities, the DSP reads sound and velocity data from the sound source ROM in accordance with the selected tone; the DSP can read rhythm data simultaneously when a rythm pattern is selected. Then it provides 16-bit serial signals containing data of the melody, chord, bass, and percussion to the DAC. The DSP also adds the selected effect to the sound data using a 256k-bit RAM.
