Early microcomputers

Thomas Eugene Kurtz (born February 22, 1928) is a retired Dartmouth professor of mathematics and computer scientist, who along with his colleague John G. Kemeny set in motion the then revolutionary concept of making computers as freely available to college students as library books were, by implementing the concept of time-sharing at Dartmouth College. In his mission to allow non-expert users to interact with the computer, he co-developed the BASIC programming language (Beginners All-purpose Symbolic Instruction Code) and the Dartmouth Time Sharing System during 1963 to 1964.

The Telmac TMC-600 is a Finnish microcomputer introduced in 1982 by Telercas Oy, a Finnish importer of RCA microchips.

The educational computer LC80 was a single-board computer manufactured in the German Democratic Republic (GDR) and intended for teaching purposes. It was the first computer that retail customers could buy in the GDR.

The Grundy NewBrain was a line of microcomputers launched in 1982 by Grundy Business Systems Ltd of Teddington and Cambridge, England. A contemporary of the ZX80 and BBC Micro, the NewBrain was mostly used in business settings. It is notable for its chicklet keyboard and models that featured a one-line display, allowing them to be used as a portable computer, in addition to television output. Another unique feature of the system was NewBrain BASIC, a BASIC programming language that featured an on-the-fly compiler.

The Compukit UK101 microcomputer (1979) is a kit clone of the Ohio Scientific Superboard II single-board computer, with a few enhancements for the UK market - notably replacing the 24×24 (add guardband kit to give 32×32) screen display with a more useful 48×16 layout working at UK video frequencies. The video output is black and white with 256 semigraphic characters generated by a two kilobyte ROM. It has no bit-mapped graphics capability. The video is output through a UHF modulator, designed to connect to a TV set.

The MCM/70 is a pioneering microcomputer first built in 1973 in Toronto, Ontario, Canada and released the next year. This makes it one of the first microcomputers in the world, the second to be shipped in completed form, and the first portable computer. The MCM/70 was the product of Micro Computer Machines, one of three related companies set up in Toronto in 1971 by Mers Kutt. It is considered by some historians to be the first usable personal microcomputer system.

Z-2 is a series of microcomputers made by Cromemco, Inc. which were introduced to the market in the middle to late 1970s. They were S-100 bus machines powered by the Zilog Z80 processor and typically ran on the CP/M operating system.

The Sol-20 was the first fully assembled microcomputer with a built-in keyboard and television output, what would later be known as a home computer. The design was the integration of an Intel 8080-based motherboard, a VDM-1 graphics card, the 3P+S I/O card to drive a keyboard, and circuitry to connect to a cassette deck for program storage. Additional expansion was available via five S-100 bus slots inside the machine. It also included swappable ROMs that the manufacturer called 'personality modules', containing a rudimentary operating system.

The TK-80 (μCOM Training Kit TK-80) was an 8080-based single-board computer kit developed by Nippon Electric Company (NEC) in 1976. It was originally developed for engineers who considered using the μCOM-80 family in their product. It was successful among hobbyists in late 1970s in Japan, due to its reasonable price and an expensive computer terminal not being required.
