TECH SPEC TUESDAY Olivetti Programma 101 About this machine: The Programma 101, or Perottina or P101, manufactured by Italian company, Olivetti, was one of the first programmable calculators mass produced. It was launched in 1964 for $3,200 (or around $32,700 in 2025 dollars). In addition to arithmetic functions, the Programma 101 was a true stored-program computer. It was built completely out of discrete devices like transistors and diodes since it predated integrated circuitry. NASA used the Programma 101 to plan the Apollo 11 moon landing. CPU: Custom transistor logic Memory: ~240 bytes Storage: Magnetic cards Graphics: Numerical displays Networking: None Notes: One of the first desktop programmable calculators Image credit: MIC Torino (Russel2), CC BY 3.0 https://creativecommons.org/licenses/by/3.0 , via Wikimedia Commons https://commons.wikimedia.org/wiki/File:MIC_Torino-Olivetti_P101.png vintage.computer

TECH SPEC TUESDAY Cray-1 About this machine: First installed at Los Alamos National Laboratory in 1976, the Cray 1 was a supercomputer that was designed and manufactured by Cray Research, led by Seymour Cray. It was the first supercomputer to implement a vector processor design which allowed it to perform a single operation on a large dataset. Priced from $5 million to $8 million each, Cray sold over 80 of the machines, solidifying both Seymour Cray’s and his company’s reputation for excellence and leading the supercomputing industry.
