Re: Decapping more Genesis chips

Hello again.
Despite all the horror that is happening in the world, we continue the decapping project of Sega Megadrive/Genesis chips.
Today I'll show you some quick previews at 10x magnifying level.
315-5364
TA-04
315-5309
TA-05
Unfortunately, we don't have now unbroken 315-5313 chip but we have TA-06W (315-5313A) one.
TA-06W
As you can see, the TA-xx chipset is a superclone but made on the thinner norms.
Also we have some MegaCD chips.
315-5540 (Fujitsu 2C31) which on the connection board.
315-5476A
315-5477 (Fujitsu 2C45)
Also we will recapture the YM2612.
YM2612
At the first look the 315-xx chipset uses standard CAD CELLs. So we need to remove metal to reach the polysilicon.
