I have a round calculator the size of a CD about an inch thick and has a padded top, with sqrt, percent and memory keys. The lid swings to the side and the base allows the calc to spin in random circles. Lid marked hp Invent and base has china sticker. Anyone know what the promotion was? I assume its a promotional item.


Hmm, I've never heard of or seen such a calculator from HP. Do you have a picture of it?

I can email a photo if I have your address.

It sounds like a promotional hand-out.

Would you care at all if I posted the photo for others to see?


Do you have any idea of the purpose of the padded lid or the swivel base?
