Old processor's die

An old chip that i opened to see what's inside.

 

It's an Intel 8742, a 8-bit microcontroller that includes a CPU running at 12 MHz, 128 bytes of RAM, 2048 byte of EPROM, and I/O in the same chip.

 

See the official doc (pdf) on the intel's website, or see a shot of the whole thing.

 

Thank you to kingey1971 for the identification !
