Agreement between Intel & NCM

The following document is a transcription of the Agreement signed by Dr. Robert Norton Noyce of Intel and Mr. Yoshio Kojima of Nippon Calculating Machine Corporation (NCM) in February of 1970 for the manufacture of a set of chips for NCM's Busicom calculators.

This historical project eventually lead to the development of the Intel 4004 and the invention of the microprocessor.

AGREEMENT

This Agreement entered into as of February 6, 1970, by and between Intel Corporation, a corporation organized under the laws of the State of California, U.S.A. whose head office is located at 365 Middlefield Road, Mountain View, California, U.S.A. (hereafter referred to as Intel) on one part and Nippon Calculating Machine Sales Corporation whose head office is located at 15-4, Uchikanda 2-chome, Chiyoda-ku, Tokyo, Japan, Nippon Calculating Machine Corporation whose head office is located at 27 komatsubara-cho, Kita-ku, Osaka, Japan and ElectroTechnical Industries Corporation whose head office is located at 7 Kanda-Mitoshiro-cho, Chiyoda-ku, Tokyo, Japan, corporations organized under the laws of Japan (hereafter collectively referred to as NCM) on the other part.

Witnesseth

Whereas: NCM is a manufacturer of various units of equipment known as Busicom Desk-Top Electronic Calculators and desirous of developing and manufacturing new type electronic calculators using large scale integrated circuits, and

Whereas: INTEL is engaged in designing electronic devices and desirous of manufacturing large scale integrated circuits for NCM to be used for Desk-Top Electronic Calculators (hereafter to be referred to as Products), and

Whereas: NCM desires to purchase "Products" manufactured by Intel upon terms and conditions hereafter set forth. Now, therefore, in consideration of the mutual convenants and obligations herein contained, it is hereby agreed by and between Intel and NCM as follows.

Article I

Products are defined as integrated circuits for read-only-memory-oriented-systems, jointly designed by Intel and NCM during the course of this agreement, now envisioned to include four circuits namely the NCM-ARU, NCM-ROM, NCM-RAM, and NCM-SHR including NCM variations of bit patterns for the NCM-ROM. The above mentioned NCM-ARU, NCM-ROM, NCM-RAM, NCM-SHR shall be equipped with the following capabilities.

NCM-ARU: The NCM-ARU is a single chip which implements and interprets all microinstructions. The NCM-ARU contains 16 general purpose 4-bit registers, a set of 12 bit registers used as a push-down stack, a 4-bit accumulator with a 1 bit carry/link stage, an operation register and instruction decoder.

The NCM-ARU provides a 4 bit data port for communication with the NCM-ROM and NCM-RAM. The NCM-ARU generates a synchronizing signal which indicates the start of an instruction cycle. The NCM-ARU also generates command signals used to control NCM-RAM and NCM-ROM operations. These signal lines can control up to 4 groups of NCM-ROM's and NCM-RAM's. A group consists of up to 16 NCM-ROM's and 4 NCM-RAM's.

The NCM-ARU implements a decimal adjust accumulator instruction so that decimal arithmetic may be easily realized.

NCM-ROM: The NCM-ROM holds 256 8-bit words of read only memory, and communicates with the NCM-ARU over the 4-bit data path. In addition to the data path, a timing and a command signal are received by the NCM-ROM from the NCM-ARU. During one instruction cycle, the NCM-ROM receives 12 bits of address information from the NCM-ARU via the 4-bit data path, and delivers 8-bits of information to the NCM-ARU over this path.

In addition to the read only storage, a 4 bit register is realized on the NCM-ROM chip. This register is provided with 4 external connections and an external control lead so that it may be used as a general purpose input/output register.

NCW-RAM: The NCM-RAM random-access read-write memory realizes 4 registers, each of which stores up to 20 four-bit characters. Of the 20 characters in each register, 4 are status characters which are directly addressed and 16 are data characters which are addressed indirectly. The NCM-RAM communicates with the NCM-ARU via the same 4-bit data path as does the NCM-ROM, and receives the same command and timing signals as do other NCM-ROM's and NCM-RAM's within the same group.

In addition to the random access memory, a 4-bit output register with 4 external terminals is also realized on the chip.

NCM-SHR: The NCM-SHR is a 10-bit static shift register to be used with NCM-ARU, NCM-ROM, and NCM-RAM as an output device. Inputs include a single data line, a single clock line, and an enable line. Ten data outputs are provided and are present only when enabled. An output which is not controlled by the enable input is provided from the last stage of the shift register so that the shift registers may be cascaded.

Intel shall supply to NCM 30 kits of production samples and NCM shall attempt to perform and complete testing of these samples within 30 days, but in no event longer than 60 days, after NCM's receipt of the samples, according to the evaluation test technique approved by Intel. The above mentioned evaluation test technique shall be decided 1 month before the delivery of production samples. If the test result is satisfactory NCM shall place a follow-on order for 3 months out of the delivery schedule decided separately. NCM's obligation to pay the development charge shall start on satisfactory completion of the test of the production samples. NCM shall submit the evaluation test report to Intel. If the result of the evaluation test is unsatisfactory, Intel and NCM shall make an effort to find the cause within 30 days based on the test report.

If the cause can not be fixed, Intel and NCM shall consult for one month in order to find the solution method with a view to smoothly starting NCM's production according to the separate arrangement provided in Article 8. If a satisfactory conclusion can not be found, the parties will go to arbitration as provided in Article 22 for solution.

Article 11 (Incoming Test of Product)

  1. Intel shall supply to NCM Product in full compliance with the acceptance test specifications decided after consultation by the two parties.
  2. The acceptance test of Product shall be applied to the entire delivery and shall be performed within 30 days after NCM'S receipt thereof.
