Got an older Intel CPU die from ebay to look at under the microscope. Grinding/dissolving to expose a die from a CPU was too much trouble, so I found someone selling these that never made it to being packaged.
K6-2 CPU (not sure what speed), 32M ram. The actual ATSC board was a double-wide PCI board joined to an ISA board with a jumper.
Intel Pentium M 735 processor.
A central processing unit (CPU) is the electronic circuitry within a computer that carries out the instructions of a computer program by performing the basic arithmetic, logical, control and input/output (I/O) operations specified by the instructions.

Here we have 2x 186 processors and a 286. Very rare to find a 186 in a PC.
The 186 was a popular chip in other applications. Many versions have been developed in its history. Buyers could choose from CHMOS or HMOS, 8-bit or 16-bit versions, depending on what they needed. A CHMOS chip could run at twice the clock speed and at one fourth the power of the HMOS chip. In 1990, Intel came out with the Enhanced 186 family. They all shared a common core design. They had a 1-micron core design and ran at about 25MHz at 3 volts. The 80186 contained a high level of integration, with the system controller, interrupt controller, DMA controller and timing circuitry right on the CPU. Despite this, the 186 never really found itself in a personal computer.
One day whilst cleaning out my shed, I found this item. I thought is was interesting enough to take a photo of.

Photo taken with a Canon 30D in Macro mode. The lens was a 18-55 mm and a macro light was used. The item was placed into a light tent.

Part of my (some people might call it junk) vintage chip collection.
The Zilog Z80 CPU, Made from 1976 onwards. This one is probably from some time in the 80's, so probably 25'ish years old.
First Thamesway 960 N960 CPU, on route 100 leaves Basildon bus station. Monday 4th February 2002,. 441-24,.

Back in the day when I was a regular hardware hacker type, I had a spare ceramic 68000 CPU on my bench, a few years old and no longer state of the art by any means. For some reason, my soldering iron was turned up to 800F. With an evil gleam in my eye, I dropped some solder on the gold lid of the case and heated it until the thing smoked. The lid - much to my surprise - suddenly slid off. I kept it all these years, and this is a scan taken with an Epson 4870 scanner. If you have noticed the scratch at the bottom of the chip, all I can say is I didn't say I kept it carefully...
