I realize there is still ongoing discussion about the "next generation" OS for the RCX, but it appears there are two immovable camps. One camp wants to do the minimum work possible and come up with an incremental upgrade to the existing firmware. (...) (26 years ago, 6-May-99, to lugnet.robotics)

Oh, I guess I should say hello first. Hello. I've been lurking for months now, but haven't joined in because school has been kicking my butt timewise, hence an inability to build. Wicked, evil university. Anyways, the semester ends next week (...) (26 years ago, 6-May-99, to lugnet.robotics)

After thinking about it some more, I think it was silly to develop the OS and the JVM port simultaneously. The initial step should be to get it running under legOS, perhaps single-threaded without GC. After that is working, we can replace the OS (...) (26 years ago, 6-May-99, to lugnet.robotics)

(...) - I agree there will be two projects - if both projects get off the ground in the first place - Partly I disagree with your characterization of the other project; I do not think the goals are quite as stated. The other group wants to (I think) (...) (26 years ago, 6-May-99, to lugnet.robotics)

BTW, we need to thank a LOT of people, people who gave time to reverse engineer stuff.. This is all due to HARD work by a lot of people.. lets not loose sight of how this all was made possible.. Excuse me if this sounded like rambling.. Cause that's (...) (26 years ago, 6-May-99, to lugnet.robotics)

This sounds reasonable. I imagine we'll be using the EmbeddedJava API for this, as this allows us to implement only the parts of Java we need or can support in the RCX. I'm a bit disappointed with the minimal info that java.sun.com provides on what (...) (26 years ago, 7-May-99, to lugnet.robotics)

(...) Actually, we can't do EmbeddedJava since that requires a full JVM including long and double, the Security manager, etc. We aren't going to be able to call it Java, since it won't pass the compatibility suite (we can say it implements a subset (...) (26 years ago, 7-May-99, to lugnet.robotics)

Aaah, good points. Do we have a preliminary list of packages that we'll need? Actually, it's easier to pick things that aren't needed and then complement it. java.awt is right out, as is java.applet. The same thing can be said for java.beans, (...) (26 years ago, 7-May-99, to lugnet.robotics)

(...) Actually, there are some things in java.math that should be there. I would expect we would have two sets of classes -- those which are built into the JVM port (ie, those required for operation like Object, Thread, etc) and those which can be (...) (26 years ago, 7-May-99, to lugnet.robotics)

I was merely ruminating on packages that might provide interesting interfaces/classes, and packages that we can toss out of hand. I wasn't trying to imply (although my post did seem that way) that we should implement ALL of java.io, just that parts (...) (26 years ago, 7-May-99, to lugnet.robotics)
