The only one I have is a Ti-30X II, bought on eBay in 2007. It is also made by the company "The Educator" and looks very similar to your HP 30S. Mine works, at least it worked when I put it in a box together with other uninteresting calcualtors ca. 15 years ago. Haven't seen it since. I also have not seen an overhead projector in 20 years.
