Processor Die Photos by Christoph Morlinghaus

I recently had the pleasure of helping noted photographer Christoph Morlinghaus with a die photo project.  Christoph takes photos with a large format 8×10 film camera, and wanted to do some of processor dies, so the museum sent him off a box of chips. After a lot of work decapping and cleaning the chips, as well as finding ones with the most interesting dies, Christoph was able to take some stunning shots, no easy feat with the long exposure times required for such a camera.  Exposure times for these shots can run into the minutes, and even something as minor as a truck driving by can create enough vibration to ruin the shot.  Dies also had to be selected to show a variety of detail, colors, and be big enough to take a picture of, ideally a half inch on a side or better.  You can view the results here on Morlinghaus.com. Some very large format prints are currently on display at the Snap! Gallery in Orlando Florida as well.

Christoph did 7 total die shots of a variety of processors spanning 15 years of computing.  Dies included are: Intel 186, 486 and Pentium (P54CS), Motorola MC68020 and MC68030 as well as a Cyrix Media GXm and Cx486DX2. A 17″x22″print of each was donated to the CPU Shack, which are now framed and hanging, where they make a very nice display, as well as truly artistic pieces.

Motorola 68020 Processor die shots and description

1985 production 68020 'XC' denotes a not fully qualified device.

1985 production 68020 ‘XC’ denotes a not fully qualified device.

In 1979 Motorola wow’d the world with the introduction of the MC68000 MACSS (Motorola Advanced Computer System on Silicon).  One of the first single chip 32-bit processors.  In 1982 the design was upgraded and revised, and released as the 68010.  Performance wasn’t that much better then the original 68k so it saw much smaller adoption.

In 1984 Motorola continued the 68k line with the 68020.  Speed was greatly improved, up to 33MHz.  It was originally made on a 2 micron HCMOS process, allowing the design to use 200,000 transistors and integrate additional addressing modes, co-processor support, and multi-processor support.

The Swedish Computer archeology blog Ehliar has a nice article and die shots on its architecture and design.  Check it out.
