The HP 33s (F2216A) was a scientific calculator marketed by Hewlett-Packard. It was introduced in 2003 as the successor to the HP 32SII,[1] and discontinued on the introduction of its successor the HP 35s in 2007.
Features
[edit]Its main features are:
- RPN or traditional semi-algebraic (infix data/algebraic operator entry/postfix one-number function entry), user-selectable
- Two-line LCD display
- Full scientific/engineering mathematical features
- Keystroke-programmable with full boolean and program-control command sets and line edit, insert and delete
- HP "equation list" equation editor (fully algebraic) in both the stand-alone list as well as in keystroke programs
- HP Solver feature (solves equations and functions for one unknown)
- Function integration feature
- All mathematical operations and features fully functional in all modes
- Unit conversion and constants
- 31 KB of random-access user memory (equivalent to about 7 KB on earlier HP programmable models)
The main differences from the HP 32SII are:
- A radical difference in keypad layout and appearance
- Memory is expanded from 2 KB to 32 KB
- Faster processor
- More functions
- Algebraic entry mode as well as RPN
- The display has two lines
- The length of an equation was now restricted to 255 characters (no arbitrary limit in the 32SII)[1]
The HP 33s was co-designed and manufactured by Kinpo Electronics of Taiwan.[2]
Reception
[edit]The 33s is generally considered to have fewer logic bugs than the HP 35s. However, the unconventional chevron-styled keypad has been regarded by reviewers as bizarre and difficult to use compared to other HP professional calculators.[3][1]
Revisions
[edit]The 33s went through numerous revisions that have solved two of the most pervasive issues people had with the early models (namely poor screen quality and bad keypad responsiveness).
