The 3193A is a support chip in the NES. The die is very small, and our images below are not reduced in size after stitching. We'll provide a die size measurement soon.
The die shot is stitched from many separate microscope shots taken with a Nikon LV150 using an LU Plan Fluor 20x objective. The images were corrected and stitched automatically by Christian Sattler in the UK, using
and custom code. The map of stitched images is shown on the right.
If you enjoy these images and our work, please consider a donation to further this work. We're a small group of enthusiasts who devote our free time and money to preserve computer technology. Your support is a valuable contribution to computer history and to preserving classic computer hardware in the public domain.
