Oberon-2
Yup, I'm sure. I run it on Win95 every day, along with Java on Sun
workstations. It's been out for weeks. I do my Java development on the Sun,
though.
The last I heard a Linux version exists, but it's very very unstable and needs
a lot of work. (That's from the guy who was doing the port). I'm really
anxious to see that port too.
