While I would identify as Wikipedia inclusionist [1], I find this article quite problematic.
It is (quite) impossible for a reader to verify any of the claims made in the article.
Five years ago, someone (probably Ken Dakin) wrote this article and no other person on the whole planet earth has apparently been able or willing to add information or support the claims of the article.
For all that we know, the WRS might just be an elaborate hoax [2] or part of a plot by someone who hates VisiCalc.
(A quick Google search turned up some further sources that suggest that at least someone calling himself Ken Dakin actually exists and claims to have worked on WRS [3].)
