Hewlett Packard - HP 33E


Brand: Hewlett Packard
Model: HP 33E
Type: Programmable scientific calculator
Picture: HP 33e
Batteries: Battery pack
Lifetime: Introduced: 1979
Terminated: 1983
Notes: The HP 33E has a twin brother, the HP 33C. The difference between these two calculators is that this one (the 33E) doesn't have constant memory, whilst the 33C does. This calculator is quite a basic programmable calculator (conform HP's standards), quite similar to the earlier HP 25. It does have some extra functions however.
