Hewlett Packard introduced in August with the HP 30b Business Professional a financial calculator centered between the HP 10bII and HP 17bII. At first glance the HP 30b seems to compete with the BA II PLUS Professional available since 2004 but it obviously offers much more bang for the bucks:
|• 15 digit calculator
precision versus 13 digits
• Calculating with exponents up to ±499 versus ±99
• Two-line display with 12 numerical digits versus one-line display with 10 numerical digits
• 7 regression models versus 4 regression models
• Programming capability
Dismantling the Hewlett Packard 30b Business Professional is different from most other calculators. The battery cover extends over 80% of the calculator surface and allows access to three screws. The remaining 2 screws are hidden under two rubber feet. Inside we located a pretty common construction with a single printed circuit board (PCB). The PCB hides the single-chip calculating circuit under a small protection blob of black epoxy and drives the graphing display with a heat sealed fine-pitch connector.
