The following components made me suspect that there is some sort of
TX-RX circuitry to connect with an external device for unknown purposes.
Maybe a kind of device to trigger remote credits...
1x TBA820 ; 2 Watt Audio Amplifier.
1x HEF4528BP ; Dual Monostable Multivibrator 3/15V.
1x MM53200N ; Encoder/Decoder. Digital Code Transmitter-Receiver System.
1x L200C ; 2.8 -> 36V. Voltage Regulator.
1x SN94501N ; Unknown... No Data.
1x BC237B ; NPN transistor.
