I stumbled upon this magazine archive. And it holds quite a few XJS related articles, so that will keep you busy untill I pick up my activities again:

I have to say they made quite a job of it. The articles are available in scans (click and then double click to enlarge it) but they also converted them in clear text which makes the reading quite easy.
