Old electronic module EPSON BIOS extract gold 3 black buttons ic chip

Today I found an old electronic module of EPSON BIOS. I'm not sure what it's used for. I'll take it apart to see if it can be used to extract gold. Are there any parts that contain gold? Let's see from what we've taken apart. You can see that it has 3 black dots of IC chip. Inside, there are a lot of gold wires. I might use this part to extract gold later. But today, we'll take it apart to see what's inside and what's interesting.
