Intel 8008 The Intel 8008 (""eight-thousand-eight"" or ""eighty-oh-eight"") is an early byte-oriented microprocessor designed and manufactured by Intel and introduced in April 1972. It was an 8-bit CPU with an external 14-bit address bus that could address 16 KB of memory. Originally known as the 1201, the chip was commissioned by Computer Terminal Corporation (CTC) to implement an instruction set of their design for their Datapoint 2200 programmable terminal. As the chip was delayed and did not meet CTC's performance goals, the 2200 ended up using CTC's own TTL-based CPU instead. An agreement permitted Intel to market the chip to other customers after Seiko expressed an interest in using it for a calculator.

IBM System/34 The IBM System/34 was an IBM midrange computer introduced in 1977. It was withdrawn from marketing in February, 1984. It was a multi-user, multi-tasking successor to the single-user System/32. Most notably, it included two very different processors, one based on System/32 and the second based on older System/3. Like the System/32 and the System/3, the System/34 was primarily programmed in the RPG II language. One of the machine's interesting features was an off-line storage mechanism that utilized "magazines" - boxes of 8-inch floppies that the machine could load and eject in a nonsequential fashion. Borrowing mainframe features such as programmable job queues and priority levels, the System/34 ran on 64K of memory.

Sony SMC-70 The SMC-70 is a computer produced by Sony from 1982. Although it resembles a home computer, it was designed for professional video generation, for example in Cable television applications, and digital video effect generation. It was the first computer that used the just invented (also by Sony) 3.5" micro floppy disk drive that later became industry standard. It had a few distinctive aspects that set it aside from many of it contemporary systems. For example, it did not use a version of Microsoft BASIC, but its own Sony developed BASIC, and it could handle and display kanji characters.

TX-0 The TX-0, for Transistorized Experimental computer zero, but affectionately referred to as tixo (pronounced "tix oh"), was an early fully transistorized computer and contained a then-huge 64K of 18-bit words of magnetic core memory. The TX-0 was built in 1955 and went online in 1956 and was used continually through the 1960s at MIT. The transistorized TX-0 computer used 3600 transistors in its computer's circuitry and had also used the Philco high-frequency surface-barrier transistors in its design. In 1953, Philco had developed the world's first high frequency surface-barrier transistor, which was also the first transistor that was 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.
