I can imagine. I'll try moving a stick of ram from one to another since they're all the same model hopefully they have the same brand/specs ram.It's going to be rough.
You'll want at least 2gb I think. I'm using 1gb at the moment with the NXT client. Not sure if Java would be better or not. NXT is supposed to better optimized for low performance machines, but my friend plays on a potato and gets better frames on Java compared to NXT. Anyway, yea ff you can swing 2gbs that'd be the best thing.
