18 songs played by an IBM 7090 computer with a digital-to-sound transducer, using punch cards. This recording contains the first songs composed and played on a computer. The songs, composed by Max Matthews and John Pierce, were recorded by Bruce Strasser at Bell Laboratories.

Two-sided long-playing phonograph record containing recordings of music by Johann Sebastian Bach played on an IBM 704.

This volume contains a mix of brief notes on the status of experimental wafers together with extended disclosures of process and design ideas that were used as the basis for patent filings. Specific entries include: "Method of protecting exposed p-n junctions at the surface of silicon transistors by oxide masking techniques" (pp. 3-4) this was his first expression of the planar process – U.S. patent 3025589; "Effect of gold-doping on lifetimes in transistors" (pp. 7-11) – U.S. patent 3108914; “Use of selective control on electron and hole lifetimes in semiconductor devices” (pp. 12-15) – U.S. patent 3184347; “PNP planar transistors” (pp. 17-18); “On the application of the Merck growing technique to device structures;” “Observations on the impact and applications of epitaxial films” (pp. 23-24); “Logic using unipolar transistors” proposes a practical method of implementing the ideas of Walmark at RCA (pp. 26–28).

<p>The Altair 8800 kit was introduced as the cover story on the January 1975 edition of Popular Electronics. Though 'home-brew' experimental systems existed well before the Altair, none had the Altair's wide- reaching popularity. Word length: 8 bits. CPU Circuitry: Intel 8080. Prymary Memory: 256 Bytes. Price: $ 397. The Altair inspired Bill Gates, then at Harvard University, to write a BASIC interpreter so that users could easily program the machine. This was the start of Microsoft. MITS was sold to Pertec and the Altair line did not last long. Paper tape was signed by Bill Gates during his appearance at the museum on Oct. 1, 2004 (acid free pen used for signature). The insrciption reads "Bill Gates Paul Allen MITS Altair 2 Mar 75."</p>

<p>Package had various price sticker labels in yen: "3980" and "4179". Sticker was removed and plastic packaging was discarded.</p>
