Sellam, I've got a manual which could be scanned - It has one of those plastic comb bindings (Acco?) which needs replacing anyway. I think it is original since the cover is the typical Tektronix type with the cutout window that shows the title page. I can make a copy, or possibly loan it to someone local (Sacramento|Bay Area) for scanning. I was planning to bring the calculator and manuals (operating+statistics) to VCF to look for an interesting trade. Russ
