Ancient Web: NS32000 Die Photographs Made Forgotten Processors Visible

Part of the Ancient Web Collection.

A computer chip usually arrives as a little black or ceramic package. The interesting landscape is hidden inside, in structures measured by fractions of a millimeter.

Explore the Series 32000 die-photo gallery.

This specialist reference is devoted to National Semiconductor's Series 32000 processor family. Its main navigation separates processors, floating-point units, memory-management chips, operating systems, and the many computers that used the architecture.

The die gallery gives the silicon itself an unusual amount of attention. It compares an NS16032 with the later NS32032, discusses the location of microcode ROM and data paths, and points out changes to power pads, marking and fabrication processes. Its captions identify dimensions and explain why merely shrinking logic may not reduce an entire chip when external connections dictate its size.

Old chips contain small surprises

A photograph of the NS32532 shows the locations of cache, control logic and microcode structures. The gallery includes a remarkably large 10,560-by-8,560-pixel die image, credited to industrial photographic equipment. Another close-up reveals names left by engineers on early silicon.

Several images came from contributors. The webmaster thanks Finnish photographer Pauli Rautakorpi for permission to show his die work and credits others for unusually rare chips. The page mentions a newly photographed NS32332 in 2023, demonstrating that this is continuing historical research rather than a frozen vintage sales catalog.

The author is careful about some uncertainties. One unusual chip carries markings whose precise development role is conjectural; elsewhere the author questions a published die-size figure after studying a wafer photograph. Those doubts are part of the value. The page invites the reader into the process of identifying actual artifacts, not just copying manufacturer specifications.

Its discussion ranges from early NMOS chips to CMOS versions and a later experimental design called Swordfish, whose die contained over a million transistors according to the cited material.

The creation date of this website has not been established from the inspected page, so it belongs here as a detailed historical preservation project, not as an assumed 1990s homepage.
