Unknown french encrypted system.
Driver by Roberto Fresca.
*****************************************************************************************
Hardware Notes:
---------------
Based on chip manufacturing should be manufactured in 1998
Specs:
------
1x Zilog Z0840004PSE (4MHz Z80 CPU).
1x GI AY-3-8910 (sound).
1x LM356N (Low Voltage Audio Power Amplifier).
ROMs: 2x 27C256 Program ROMs (I, II).
3x 27C256 GFX ROMs (R, V, B).
RAMs: 1x KM62256ALP-10 (near prg ROMs).
2x CY6264-70SNC (Near GFX ROMs).
1x oscillator 18.432 MHz.
1x 8 DIP Switches bank (near ay8910).
1x Volume Pot (betweeen the audio amp and ay8910).
1x Motorola MCT1413 (High Current Darlington Transistor Array, same as ULN2003).
1x 2x28 Edge connector (pins 1-2-27-28 from component side are GND).
