Almost certainly the biggest player in the Epson QX-10-specific software world was Rising Star Industries, the creators of Valdocs and its various successors. Valdocs is an integrated software suite that (as I understand it) was generally packaged with Epson QX-10 machines. RSI pretty much tied its future to the QX-10 (and to the QX-16) with Valdocs, and when the QX-10 lost favor with the public, RSI went down with it. But in its heyday, they produced a newsletter called The Rising Star, with some articles on the background of the company, tips and tricks in Valdocs, new versions, etc.
I have gotten ahold of four of these. I don’t know if there are others out there anymore, but here are the ones I have:
- The Rising Star, v1n4, Fall 1984
- The Rising Star, v2n2, Feb 1985
- The Rising Star, v2n4, Nov 1985
- The Rising Star, v3n1, Jan-Feb 1986
