★ exereunesis · 32-bit teardown · 1994 ★

Sony's first console put a 32-bit MIPS CPU, a dedicated geometry coprocessor, and a CD-ROM drive into one cheap box — and made real-time 3-D the default. Affordable polygons and cheap discs broke the cartridge era open and turned Sony into the industry leader overnight.

The Four Natures

each piece emerges by one of four natures

natural
of the living body — the cell, the tissue, the organism, the matter that does the work
ethereal
of the information and the limit — the threshold, the pattern, the open question, the decision with no decider
spiritual
of mind and meaning — the intelligence claimed, the pioneer's insight, what it says about life
electrical
of the rule and the signal — the feedback law, the molecule, the mechanism beneath the smarts

The Idea

the three-beat story

A 32-bit MIPS Brain
the CPU + GTE

The CPU is a 32-bit MIPS R3000A at ~33.9 MHz, with a Geometry Transformation Engine bolted on to crunch the matrix math that 3-D needs. Together they fed the GPU a steady stream of transformed polygons.

Polygons, Cheaply
the GPU

The GPU drew flat and textured triangles fast — no hardware floating point or perspective correction, which is why PS1 textures famously warp and 'wobble'. But it was cheap, and good enough to make 3-D mainstream.

Discs Change Everything
the CD-ROM

A double-speed CD-ROM held hundreds of times more than a cartridge, at a fraction of the cost — enabling FMV, CD-quality soundtracks, and sprawling games, and pricing cartridges out of the mainstream.

The Reckoning

the teardown, and the honesty about it

The Domain: Open It and Spec It

the teardown

  • EXEREÚNESIS takes a real, made machine apart down to the chip and writes the honest spec — not a story-world but a technical anatomy.
  • >One of a growing series of console teardowns; siblings link from the marquee.

Two-Layer Honest

datasheet vs lore

  • Settled: the R3000A CPU, the GTE, the GPU's fixed-point/no-perspective-correction rendering, the SPU, and the CD-ROM are documented (the texture warping is a real, known consequence).
  • Flagged: 'made 3-D mainstream' is a fair industry summary, not a claim it invented 3-D — stated as impact, not invention.

Render, Not Invent

sourced

  • Summarized from the public technical record for the SONY PLAYSTATION · PS1; the manufacturer and its engineers are cited, not minted.
  • No ROMs, BIOS, or copyrighted code are reproduced. Emergents are physical components; the block diagram is an illustration, not a schematic.

The Roster

every chip and part as an ACI .agent — each a birth certificate & a nature (7)

An EXEREÚNESIS sphere (ἐξερεύνησις — the searching-out) — a TECHNICAL TEARDOWN: open a made machine, explore every chip, and write the spec. Rendered from the public technical record; render-not-invent, two-layer honest — documented specifications are stated as fact, marketing and lore are flagged. No ROMs, BIOS, or copyrighted code are reproduced. Manufacturers and engineers are cited, not minted. Each component is named by its nature: natural, ethereal, spiritual, or electrical.
