TRIPOS
The
TRIPOS operating system was developed in
1978 at the Computer Laboratory in
Cambridge University.
Most of Tripos was implemented in
BCPL. The
kernel and device drivers were implemented in
Assembly language.
Tripos was ported to a number of machines, including the Data General Nova 2, the Computer Automation LSI4, plus
Motorola 68000 and
Intel 8086 based hardware, and included support for the
Cambridge Ring local area network. More recently, Martin Richards (Tripos' originator) produced a port of Tripos to run under
Linux, using BCPL Intcode.
Tripos provided features such as pre-emptive multi-tasking (using a simple highest priority free-to-run scheduler), a hierarchical file system and multiple command line interpreters.
It formed the basis for much of the code of early versions of the AmigaOS.
Compare with the much older meaning of "tripos", as in "Natural Sciences Tripos".
