HP Forums

Found on the Adafruit website: links to interesting articles by Jean-Louis Gassée:

Part 1: Leading

Part2: Decomposing

(edit: links corrected; thanks to Albert)

Thanks for the links.
However, it does not work. This is the fix:

Part 1: When HP Led

Part 2: Why HP Fell

Interesting articles, but the links seem to be broken. A quick search locates them though.

The HP35 was sold in retail outlets and university bookstores.
