I was looking for info on a quite old Toshiba calculator and Serge Devidts's CalcMuseum had no information about it. Instead I found some data and much more at Dentaku Museum.
The website is in Japanese and you will need the help of Google Translate to go past pictures, dates and prices in the text. There is a whole new world behind the language barrier.
I do not own enough calculators to open a whatsoever museum (23 items at the moment). I had planned to show them at work on my desk, but with the 2020 pandemic that idea has been put on hold.
