Intel Allows Release of Full 4004 Chip-Set Details

Posted by timothy on from the cool-move-from-the-valley dept.

mcpublic writes "When a small team of reverse engineers receives the blessing of a big corporate legal department, it is cause for celebration. For the 38th anniversary of Intel's groundbreaking 4004 microprocessor, the company is allowing us to release new details of their historic MCS-4 chip family announced on November 15, 1971. For the first time, the complete set of schematics and artwork for the 4001 ROM, 4002 RAM, 4003 I/O Expander, and 4004 Microprocessor is available to teachers, students, historians, and other non-commercial users. To their credit, the Intel Corporate Archives gave us access to the original 4004 schematics, along with the 4002, 4003, and 4004 mask proofs, but the rest of the schematics and the elusive 4001 masks were lost until just weeks ago when Lajos Kintli finished reverse-engineering the 4001 ROM from photomicrographs and improving the circuit-extraction software that helped him draw and verify the missing schematics. His interactive software can simulate an ensemble of 400x chips, and even lets you trace a wire or click on a transistor in the chip artwork window and see exactly where it is on the circuit diagram (and vice-versa)."

    When we get the Core i7 details, will it seem as quaint as the 4004 does now?

      I mean with the 4004 everything was realy, realy basic. It had a design team consisting of four people. Nowadays it takes a whole team to improve it all.

      Yes, one person for each bit. Nowadays you need 64 or 128 person teams.

    ...run Linux?

    j/k

    This should actually be quite cool. I can see garage-based tinkerers messing with this chip, the registry and even coming up with a retro User Group.

      Can you compile a Linux kernel into 2048 bytes?

    4004 - chip not found.

  4. Non commercial use? by serviscope_minor · · Score: 3, Funny

    Available for non commercial use? Are they even entertaining the possibility that somoent might try to profit from the design?
