Hello and thanks a lot for the links. Ididn't know about such a Japanese cooperation of HP. Do you have any more information about this joint venture ?

Kind regards




From back in 2003...David Smith said:

"I know a lot of the Yokogawa calculators were just regular HP calculators with Japanese labels. Mike Davis had Yokogawa HP65 last year."


I saw one when I was in the house of a japanese friend of mine in Tokyo back in the early 90's. If I am correct it was a 35.


Yokogama - HP Link


Great. Something more to collect!


The HP for the HP calculator collector who has everything !

Out of my reach, however. Run run !!


One thing I have noticed about Yokogawa calculators... they all have had very poor condition labels.
