A closeup of the edge of the 486 showing bond pads with bond wires attached. Note the complex I/O driver block next to each bond pad. The pads in the center (without drivers) are two of the power and ground supplies. Note the thick vertical lines distributing power/ground to the chip.

@gsuberland It was supposed to be 7155x10870 :(
I edited the post to add a Google Drive link; hopefully that's better.

@kenshirriff ah yeah your server will have resized it then. weird final resolution though, I guess it limited based on compressed JPEG size?
