Hello Katie

I actually wanted to quote not your text but your icon. Can any moderator tell how this is done?

Anyway, I found another HP hommage to itself in the woodstock series.

The segment driver chips are able to show only the 10 numbers and five letters. In the HP-21 calculator the letters H and P are coded and could be displayed, but they never appear.

In the HP-25 the segment driver was changed, because they wanted to show the "OF" message when overflow occured, and replaced the letter H by F, much to the displeasure of Mr. Hewlett.

Later in the HP-97 They needed another letter C for displaying "Crd", made again a redesign of the segment driver, and sacrificed the letter P, which now Mr.Packard maybe should have disliked.

So gradually and calmly, the engineers removed their masters from their products.
