Notice

*1 : External PAL is needed.

*2 : External wavetable synthesizer (ex.OPL4-ML/ML2) is mixed as analog signal using external DAC.

*3 : Clock module (ex.MK1420) is used to generate the clock for OPL4-ML/ML2 and it will be mixed analog signal by having an additional DAC.

*4 : External TTLs (ex.LS138) is needed.

See section 1-2 and 1-3 for implementation detail.
