MetaComCo (MCC) was a computer systems software company started in 1981 and based in Bristol, England by Peter Mackeonis and Derek Budge. A division of Tenchstar, Ltd.
MetaComCo's first product was an MBASIC compatible interpreter for IBM PCs, which was licensed by Peter Mackeonis to Digital Research in 1982, and issued as the Digital Research Personal Basic, running under CP/M. Other computer languages followed, also licensed by Digital Research and MetaComCo established an office in Pacific Grove, California, to service their United States customers.
In 1984 Dr. Tim King joined the company, bringing with him a version of the operating system TRIPOS for the Motorola 68000 processor which he had previously worked on whilst a researcher at the University of Cambridge.
This operating system was used as the basis of AmigaDOS (file-related functions of AmigaOS); MetaComCo won the contract from Commodore because the original planned Amiga disk operating system called Commodore Amiga Operating System (CAOS) was behind schedule; timescales were incredibly tight and TRIPOS provided a head start for a replacement system.
MetaComCo also developed ABasiC for the Amiga, the first BASIC interpreter provided with Amigas. MetaComCo also worked with Atari Corporation to produce the BASIC initially provided with the Atari ST in 1985: ST BASIC.
The company also sold the Lattice C compiler for the Sinclair QL and the Atari ST and range of other languages (e.g. Pascal, BCPL) for m68k-based computers. MetaComCo also represented LISP and REDUCE software from the RAND Corporation.
Several of the team at MetaComCo went on to found Perihelion Software. Mackeonis founded Triangle Publishing, the software publishing company responsible for creating the ST Organizer for the Atari ST and PC Organizer and Counterpoint (a GUI system) for Amstrad Computers and GoldStar computers.
MetaComCo BASIC was available on the Singapore Teleview videotext receiver.
MetaComCo was disestablished in 1988

The mkdir (make directory) command in the Unix, DOS, DR FlexOS, IBM OS/2, Microsoft Windows, and ReactOS operating systems is used to make a new directory. It is also available in the EFI shell and in the PHP scripting language. In DOS, OS/2, Windows and ReactOS, the command is often abbreviated to md. The command is analogous to the Stratus OpenVOS create_dir command. MetaComCo TRIPOS and AmigaDOS provide a similar MakeDir command to create new directories. The numerical computing environments MATLAB and GNU Octave include an mkdir function with similar functionality.
TRIPOS (Trivial Portable Operating System) is a computer operating system. Development started in 1976 at the Computer Laboratory of Cambridge University and it was headed by Dr. Martin Richards. The first version appeared in January 1978 and it originally ran on a PDP-11. Later it was ported to the Computer Automation LSI4 and the Data General Nova. Work on a Motorola 68000 version started in 1981 at the University of Bath. MetaComCo acquired the rights to the 68000 version and continued development until TRIPOS was chosen by Commodore in March 1985 to form part of an operating system for their new Amiga computer; it was also used at Cambridge as part of the Cambridge Distributed Computing System. Students in the Computer Science department at Cambridge affectionately refer to TRIPOS as the Terribly Reliable, Incredibly Portable Operating System. The name TRIPOS also refers to the Tripos system of undergraduate courses and examinations, which is unique to Cambridge University.
Perihelion Software Limited was a United Kingdom company founded in 1986 by Dr. Tim King along with a number of colleagues who had all worked together at MetaComCo on AmigaOS and written compilers for both the Amiga and the Atari ST. Perihelion Software produced an operating system for the INMOS Transputer called HeliOS. This was a system that looked like Unix but which could pass messages to processes running on either the same processor or another one. This was used in the Atari Transputer Workstation, among other places. Later HeliOS was ported to other processors including the ARM architecture. Perihelion Software also produced an in-memory database system called Polyhedra. The group responsible for this product was set up as a subsidiary, Perihelion Technology Limited (PTL), which did a management buyout in 1994. PTL later changed its name to Polyhedra plc in 1995, and in 2001 was acquired by a Swedish company called ENEA.
Before the 1921 destruction of Tulsa’s Greenwood District, Black residents had created a remarkable center of business and community life. The district included stores, professional offices, entertainment venues and homes owned by Black citizens. Understanding Greenwood means learning what was built—not only what was burned.
