Nintendo NES RP2C02 Die Shots

Thanks to Joey Parsell in Indiana for the chips.

MOS 8501 R1 Die Shot

A new die shot!  MOS 8501 R1 from 1984.

AMD 8085 die shot and first layer images

You thought Intel was behind the 8085, so why in the world would we list an "AMD 8085?"  Back in the day, computer manufacturers would insist on having several independent producers of a chip to guarantee supply.  AMD was a second source producer of the 8085, having licensed the design from Intel.  Can you imagine an AMD or NVIDIA Core i7 today?  Things aint what they used to be.

Pavel Zima has done a great job extracting components into per-layer images.  So far, we have only metal and vias, as we'll need to delayer the chip before we can see details under the metal.

CTIA Die Shot

Here's our latest die shot:  the Atari C012295 CTIA.

We've had a die shot of the follow-on C014805 GTIA for a while, and can now compare the two nearly identical chips to find out what was improved and fixed in moving from the CTIA to the GTIA.
