The first sign of HP-35’s ln(2.02) bug

[teenix]

I read the fascinating document "Remembering The HP-35A" by Richard J. Nelson and this is a bit of what he had to say...

"Exactly when the bug was found I don’t remember or have, at this time, documentation to determine the date."

There are a couple of scans of the HP explanation and voluntary recall documents included but no dates.

I found a mention of a Red Dot model being repaired on May 4 1973.

cheers
