MetaComCo
The portable TRIPOS operating system kernel, originally developed at Cambridge University and written in BCPL , was commercially available by Tim King through MetaComCo, Ltd. (Bristol, England).
The DOS component of the AmigaOS emerged from this . MetaComCo also developed the BASIC interpreter ABasiC for this platform, but it was of no practical importance, as did various tools (editor, assembler ) and compiler (BCPL, C, Pascal).
Later King, who is also known as the father of the Atari-ST - BASIC ( ST BASIC ), developed transputer operating systems ( HeliOS , HOS) at Perihelion Software Ltd.
