What is the HP49?
The HP49G is Hewlett-Packard’s latest graphic calculator. It has 512K of RAM (split into two 256KB ports: Port 0 and Port 1) and 2MB of flash memory. 1MB of flash memory is used by the upgradeable ROM and the other 1MB is available to the user (in Port 2). It has the same 4 MHz Saturn CPU as the 48G series, but the software is rewritten to make the calculator operate more quickly. Although the screen is still 131×64, it is black instead of blue resulting in much higher contrast. The keyboard has 51 keys, but the ENTER key is now small and in the lower-right corner like the ENTER key on most other brands’ graphic calculators. The keys are rubber but they still have a tactile feel. In alpha mode, the arrow keys, numbers, and backspace key all still work without having to switch off alpha mode. The case is a metallic light blue with a translucent blue-tint slide-on cover. The calculator still fits in the HP48 soft case if you prefer. The piezo beeper and the clock are retained, fortunatel
