I just received an HP-38C, like new condition, boxed. The calculator has two "n" keys. It does not seen to have been opened. The former owner said that it belonged to his uncle who died. He believes that it has not been repaired. The serial number ends with B01234.
Any idea about this?
Thanks, Danton
Maybe an error during production? Upper right corner's key should be FV (future value), blue shifted Nj.
Production goof. Stuff happens.
Depending on your priorities and interest, this mfg. error produced a machine that is either annoying to use (having to recall the 2 functions names that should be visible) or rare and hence more valuable than a normal 38C. Both are true, but which matters more is up to you.
I made a label with the missing key. See picture. Now I can use it, and return to double "n" keys if I want. Thanks for comments.
