Was there Cyrillic text visible on Intel 386 chips after decapping?

There was Cyrillic text on some Intel 386 chips, but you had to do something special to see it.

Imagine you have a toy car that’s really tiny inside, like the size of a grain of sand. To see what's inside, you need to take off its shell, like peeling back a sticker from a candy bar. This process is called decapping. When someone did this to an Intel 386 chip, they found little letters written in Cyrillic, which is the alphabet used in countries like Russia.

These letters weren’t just for show, they helped engineers know where they were on the chip while working on it.

Sometimes people use Cyrillic instead of Latin letters when writing on tiny things. It's like using a different kind of label, maybe one that’s easier to read under a microscope or fits better in a small space.

So, if you had a magnifying glass (or even a really powerful one), and you peeled back the shell of an Intel 386 chip, you might see some Cyrillic text hiding inside!
