BELLMAC-8
The MAC-8, better known today as the BELLMAC-8, is an 8-bit computing, 8-bit microprocessor designed by Bell Labs. Production began in CMOS form at Western Electric as the WE212 in 1977. The MAC-8 was used only in AT&T products, like the 4ESS. No commercial datasheet, spec sheets were published, so it is little known as a result. The best-known use, in the public, is the MAC-TUTOR computer trainer, released in 1979. The MAC-8 was designed to run high-level programming languages, in particular, Bell's own C programming language. An uncommon feature of the system is that its assembler language was deliberately written to resemble C code, including support for variables and high-level constructs like for loops. In contrast, most assemblers of the era mapped much more directly onto the low-level opcodes of the processor and lacked higher-level features. The MAC-8 was followed by the BELLMAC-80, a 32-bit system very different from the MAC-8 internally, but maintained the concept of bei ...

Bell Labs
Nokia Bell Labs, commonly referred to as ''Bell Labs'', is an American industrial research and development company owned by Finnish technology company Nokia. With headquarters located in Murray Hill, New Jersey, Murray Hill, New Jersey, the company operates several laboratories in the United States and around the world. As a former subsidiary of the American Telephone and Telegraph Company (AT&T), Bell Labs and its researchers have been credited with the development of radio astronomy, the transistor, the laser, the photovoltaic cell, the charge-coupled device (CCD), information theory, the Unix operating system, and the programming languages B (programming language), B, C (programming language), C, C++, S (programming language), S, SNOBOL, AWK, AMPL, and others, throughout the 20th century. Eleven Nobel Prizes and five Turing Awards have been awarded for work completed at Bell Laboratories. Bell Labs had its origin in the complex corporate organization of the Bell System telepho ...
