I've commented along this before, but it still still seems like an obvious and relatively easy thing, to me.
I've yet to see a point-by-point feature comparison between the two editions of ROS.
This strikes me as an ideal starting point for an effort to bring them up to some kind of parity. It could also be a cooperative project - do it on Wikipedia, for instance.
Starting with the highest common baseline, whatever that is. RO5 didn't start from RO4, did it? That was finished and put on the market by ROLtd. So what is the last common ancestor? RO3.7? Some unreleased Acorn test version of RO4?
Identify that, and then start compiling a list of the new features, in 3 columns:
- features shared by RO5 and ROL's Select/Adjust/RO6
- enhancements only in RO5
- enhancements only in S/A/6
Initially, it doesn't need to be a super-detailed programmmers' reference, just a guide for users.
I have seen dozens of beginners' guides to RO, which seem rather pointless to me in 2007 when there can be few newcomers to RO. Let's see a guide to the new stuff for people who last used RO3. Given 2 of these - a guide to the new stuff in RO5, and a guide to the new stuff in ROL's versions, then a comparison shouldn't be hard, should it?
