Idris (operating system)

Idris is an operating system. White Smiths Ltd. from Westford (Massachusetts ) was published. The product was commercially available from 1979 until 1988.

Background

Originally Idris was written by PJ Plauger and was a unixoides real-time system for the DEC PDP - 11th Plauger began his work on Idris in August 1978. Idris was binary compatible with UNIX V6 on the PDP -11, but it was also on systems without a memory management (DEC LSI -11 or PDP-11/23 ) work. The kernel required 31 kB of RAM, and the C compiler was similar.

Ports

Later, it was also ported to other platforms, such as VAX, Motorola 68000, Intel System/370 and 8086th

In 1986, Atari ordered the company Computer Tools International to port Idris on the Atari ST.

A special version of Idris ( CoIdris ) was a. Com file under MS -DOS and DOS used for I / O services. Idris was ported to the Apple Macintosh by John O'Brien ( White Smiths Australia) and was until the early 1990s available.
