Software by D'Zign released the Surveying Pac software for the HP49g+ calculator, which runs on a 75 Mhz ARM9 CPU at approximately 15 times the speed of the outmoded HP48 model. D'Zign's Surveying Pac is sold on 32 Mb cards with 30 Mb of that available for the user, but may be removed after the software has been installed, allowing the user to increase the expansion memory to suit his or her needs.
