Dual SN76489 is supported on Game Blaster or the TexElec SAAYM though.
well, i gathered some information about SAAYM. i found it's two SAA1099 on SAAYM instead of two sn76489 and i didn't find any information about Game Blaster. so, which sound card support dual sn76489 and do you have any resource about these cards? i'm tring to integrate these cards on my board such as AdLib which i have got schematic diagram of RadLib.
by the way, i didn't notice the frequency of clock which is driving the chip is from a fourfold frequency divider, so my clk freq is 14.31MHz / 3 = 4.77MHz
