- ?: Metex KS57C2016 (possibly a Samsung KS57C2016 4-bit microcontroller with custom Metex firmware?) (marking: "Metex 95D3 KS57C2016-13 013D 95D3")
- ?: 4.1856MHz crystal (?)
- ?: 14027B PBD005
- ?: 2x 0138 817B Y
- ?: OP-07 1035B JRC
- ?: Intersil ICM7555CBA (datasheet) (marking: "7555 CBA P136FAM")
- Quad analog switch/quad multiplexer: ON Semiconductor 14066B (datasheet) (marking: "14066B PBV139")
- ?: New Japan Radio (JRC) NJU4011B (marking: "NJU4011B JRC A1015H")
- Low level, True RMS-to-DC converter: Analog Devices AD636JH (datasheet) (marking: "AD 636JH 0122")
