Hello! This is #nakeddiefriday and it's the last one this year! What better way to end it than putting out something classic. And today I got just that: the 6502 by MOS! There is really no need to write more on what this chip was and what impact it had. Enjoy scrolling around the full-resolution image!

I would like to thank @root42 for supplying this particular sample!

I wish you all merry holidays and hope to see you next year for more high-quality die shots.

Hello! Hello. It's #nakeddiefriday today, and I wanted to show you one of the older works. This is an automotive ASIC fabbed for Toyota, part number DF028. I do not know the function of this particular device.

And hey, since the weather is absolutely abysmal today, I will treat you to another die shot as an extension of #nakeddiefriday.

This is КР1810ВМ86, an otherwise identical clone of Intel 8086 made by Soviets at an unknown plant.

The 8086 was extensively reverse-engineered by @kenshirriff -- give his blog a read!

Hi there! This is #nakeddiefriday again!

Today I'd like to present you one of frequent sources of pain for C64 owners, the infamous PLA. This is MOS 7700R2. They failed way too often, and considering this is custom silicon, the only option was to get another one of the same.

Many thanks to @root42 for providing this sample!

Happy #nakeddiefriday to everyone! Let's get this ball rolling.

Today we have a real classic, the MC6845 by Motorola. This is a CRT controller chip used in quite a few video adapters back in the day.

Thanks to @gloriouscow for suggesting this one! We'll do a short thread looking around.

Yo all, it is Friday now where I am, so might as well get the #nakeddiefriday thing going.

Today's guest is the famous NES PPU chip, RP2C07A by Ricoh. What's interesting about this particular sample is that it's very very dead. Many thanks to @root42 for supplying it!

As always, a short thread follows. Why not give this one a boost while you're here? :D

Note the die is oriented the same way Visual 2C02 has it: https://www.nesdev.org/wiki/Visual_2C02
