Mahidol Wittayanusorn School32 The first microprocessor chip, the Intel 4004, containing 2250 transistors on a single chip.
Mahidol Wittayanusorn School33 This is a picture of a complete general purpose computer, here about twice actual size, from the cover of Scientific American (May 1975). The computer was made by Teledyne Systems Company from chips manufactured by National Semiconductor Corporation. The two largest chips, in the center, were integrated circuits containing what at the time was the remarkable capacity of six thousand transistors each. These two chips controlled the four slightly smaller chips devoted to arithmetic and logic circuits, and the numerous other chips.
Mahidol Wittayanusorn School34 The Apple prototype (1976) —using a Mostek 6502 microprocessor, four kilobytes of memory, and a cassette recorder for storage of programs and data—can now be viewed in the Smithsonian Institution.
