HP67 Calculator

Full emulation of the classic and ground breaking HP-67 calculator produced back in the early 70's. An amazing device developed by Hewlett Packard which is still very useful.

Note: newer Galaxy 8 Plus (and similar phones) have "full screen" modes that you can change in Settings/Screen/Full Screen that can be changed on per-app basis. Insure this mode is disabled for the HP-67 app. It will fix issues with button presses being offset from buttons.

经典与突破HP-67计算器的全仿真制作早在70年代初。惠普公司开发的一种神奇的装置，这仍然是非常有用的。

注：新银河8加（以及类似的电话）有“全屏”模式，你可以在可以在每个应用的基础上改变设置/屏幕/全屏改变。确保这种模式专门针对HP-67应用程序禁用。这将解决与按键操作的问题，从按钮被抵消。
