Nice work! Great collection, enhanced by the knowledge of owning every model in the collection. I also love the included "analog" calculators, slide rule and abacus. I look forward to further additions to the collection. Do you accept donations?
I am saddened by the absence of anything HP, but I can see there is no need to duplicate the Museum of HP Calculators, so it would be nice to add that one to the Other Calculator Sites page.
