About two years ago I rescued an old AIM/65 with its original documents and many papers. Recently I took a look at those papers and found some interesting information. Comelta not only imported and distributed the AIM/65 in Spain: over time their "expansions" for it became part of a stand-alone computer mounted in a backplane. Prior to the release of "Drac-1" ("Dragon-1" in Catalan), they called it CR-System and apparently its boards were sold apart. While some of the boards are known, I found more board references which can help in making a more comprehensive list. I also found some prices and a release date for some of the boards. My backplane pinout document is slightly different from the only other source I found (mine has a battery supply line). Additionally it is also headlined with "Development Laboratory".
Unfortunately, there are no schematics but simple descriptions for many of the boards. I uploaded the scans here.
