The influential 8086 processor is 42 years old this month, so I took high-res die photos to celebrate. The 8086 is the origin of the x86 architecture still used by most desktop and server computers. Its microcode bits are visible under the microscope. https://t.co/uFoPo051BJ

Tube driven switching power supply ...
If you think switch-mode power supplies are a new thing, think again. Here's a tube-based SMPS from a 1940s teletype.
