Hi,
for PORTOS you should contact OMS directly; my private library contains
some prints dating from 1997 with the following URL:
www.oberon.ch/portos/index.htm
with the titles:
- Portos
- A hard real time operating system
paper by C. Pfister and D. Dietz, appeared in the Proceedings of the 2nd
Component User's Conference , July 14-18, 1997, Munich, Germany
and
1998 with the following URL:
www.oberon.ch/rtos/rts/index.htm
with the titles:
- JBED Next Generation Run-Time System ...
- JBED White Paper
The real background for all this is a RTOS named XOberon, developed by
Roberto Brega and Sur Vestli at the Institute of Robotics (Institut für
Robotik) at ETH, Zürich, from which Portos and later JBED have been
derived. It was/is written in Oberon-2; and may be the sources (they were
public, I saw some part of them at that time) are still opensource. This
system still is existing, maintained and developed, you can find further
information at
http://www.ifr.mavt.ethz.ch/research/xoberon/
Regards
Harro
