Editing TRON

{{stub}}
'''TRON''' — '''The Realtime Operating Nucleus''', was a Japanese project for creating a standard open computing platform for all tiers of computing: from embedded and industrial ("ITRON") to personal/business computers ("BTRON").
It was initiated in 1984, spearheaded by Dr Ken Sakamura at Tokyo University.

Notable for BTRON was that it had a novel [[ergonomic keyboard]] and used [[graphics tablet]]s as pointing devices and for input of Kanji.
Adoption of BTRON in Japan was however effectively suppressed after pressure from the USA on the Japanese government.

The only widely adopted part is ITRON, which being a realtime OS for embedded applications has been in billions of devices, including cell phones, industrial robots and automobiles.
It is succeeded by the ''T-Kernel'' realtime operating system.

TRON also suffers from lack of documentation in other languages than Japanese, and from its name being used by other things.
