Welcome to the new HP Collection:

HP-Collection shows vintage Hewlett Packard calculators and their accessories. There is no forum on my site, because there is a frequently used one on the MoHPC. site. So my page is not a competitive product, but it´s an addendum to Dave´s site. I will especially focus on the accessories of the calculators.

Note: This is an online documentation and not a physical collection.
