caption_attribution_description: English: The MIT TX-0 Transistorized computer used 3600 Philco surface-barrier transistors in its circuitry. These transistors were encapsulated in plug-in vacuum tubes, which made it easier for testing, evaluation, and replacement.
context_page_description: The TX-0, for Transistorized Experimental computer zero, but affectionately referred to as tixo, was an early fully transistorized computer and contained a then-huge 64K of 18-bit words of magnetic core memory. Construction of the TX-0 began in 1955 and ended in 1956. It was used continually through the 1960s at MIT. The TX-0 incorporated around 3600 Philco high-frequency surface-barrier transistors, the first transistor suitable for high-speed computers. The TX-0 and its direct descendant, the original PDP-1, were platforms for pioneering computer research and the development of what would later be called computer "hacker" culture.
