58-writephi-devices
This is the technical specification. The deliverable it describes is the full 58-writephi-devices blueprint package.
Enterprise blueprint packages settle by wire transfer — their value is above any card ceiling. Request the package below and a reference number is emailed to you straight away. The package ships to you on a Blu-ray disc once the wire clears, so include the address it should be mailed to.

WritePhi Devices is a Windows-compatible product family built on the WritePhi fabrication platform (Project 57). One physical PCIe 5.0 ×8 add-in card serves two distinct Windows-driver personas — the buyer selects the persona at purchase:
Same PCIe 5.0 ×8 card. Different firmware. Different Windows driver. Persona selected at boot via strap resistors R1 / R2 on the card. Both firmware images reside in on-card NOR flash; the AutoPhi 1Z-Edge bus master reads the strap at cold power-up and loads the matching persona.
Read section 3 for $1.90Project 58 introduces the V2 package — a redesigned die-carrier architecture that makes WritePhi dies volume-manufacturable, pick-and-place-compatible, sea-freight-shippable, and field-serviceable at production sample count. Every WPD-CSD and WPD-ACCEL card uses V2 packaging. Four sub-components, each with its own specification:

Cross-language wrappers planned: Python (pywpd, ctypes), C++ (header-only RAII), C# (.NET P/Invoke), Rust (wpd-rs crate).Firmware runs on the AutoPhi 1Z-Edge bus master. Language: C. Two persona images share a common base runtime; each is stored in NOR flash and selected at boot by the persona-strap resistors.
Read section 8 for $1.90Project 58 is arms-length from Project 57 per portfolio firewall. Same architecture family (both use WritePhi dies + AutoPhi 1Z-Edge). Separate SKUs, separate contracts, separate revenue streams.
Read section 9 for $1.90The store sells downloadable engineering-package blueprints, not physical hardware. Buyer picks the specific blueprint(s) they want. Each sub-blueprint ships as its own self-contained zip.
Read section 10 for $1.90Personal + educational use only; no commercial rights.

Read section 14 for $1.90What does NOT convey (retained by the inventor at every tier):
Read section 15 for $1.90This is not a patent licence and not a patent assignment. This is a documentation + commercialisation-rights transaction.
Read section 16 for $1.90No cleanroom. No PCB rework. No soldering iron. Individual dies are user-replaceable in the field.
Read section 17 for $1.90This package ships on a single Blu-ray disc, posted to the delivery address on your order. The archive on the disc is AES-256 encrypted; the passphrase is sent separately, by email, once the disc is despatched — so the disc alone is of no use to anyone who intercepts it.
Read section 18 for $1.90Discs are despatched by tracked, signed-for post. Allow 5 business days for mastering and verification before despatch.
