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.

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.
