I did NOT knew anything about sound generation, so obviously, I decided to make an ASIC for sound!

I made a replica 8-bit classic SN 76498 from Sega Master System & BBC Micro.

Thanks to @matthewvenn and #TinyTapeout I am going to have my chip on 130nm!

Image The chip is quite simple - it has 4 channels: 3 square tones and noise. The replica is less than 1500 logic gates and 64 chips like that could fit in 1 mm^2.

And it fits on a single #TinyTapeout tile.

Curiously, total wire length is 46 mm! Image
