Hardware based on auction picture:
ES-9104 PCB:
Z80A: Two Z80A CPUs frequency unknown (3MHz? 12MHz/4) (CPU2 used mainly for sound effects)
YM2203: frequency unknown (music + sound effects + video scrolling access)
ES8712: frequency unknown (samples)
OSC: 12.000MHz
other: 8-position dipswitch x 4, 3.6v battery + reset push button
Standard 8-liner harness connectors.
This is so far what could be reverse-engineered from the code.
BEWARE : these are only suppositions, not facts.
Featured hardware
2xZ80 ; frequency unknown (CPU2 used mainly for sound effects)
2xYM2203 (or compatible?) ; frequency unknown (music + sound effects + video scrolling access)
1xES8712 ; frequency unknown (samples)
