The Happy Hacking Keyboard (HHKB) is a small computer keyboard produced by PFU Limited of Japan, codeveloped with Japanese computer scientist and pioneer Eiiti Wada. [1] Its reduction of keys from the common 104-key layout down to 60 keys in the professional series is the basis for it having smaller overall proportions, yet full-sized keys.
The Happy Hacking Keyboard is a small computer keyboard codeveloped with Japanese computer engineer Eiti Wada, manufactured by Fujitsu Takamisawa Component Limited, and debut in 1996. It was expensive to enter the American OEM market, so PFU released the Happy Hacking Keyboard Lite which was manufactured by Chicony Electronics .
Eiiti Wada (和田英一, 1 June 1931) [1] is a computer scientist and emeritus professor at the University of Tokyo [2] and the Research Director of Internet Initiative Japan (IIJ), a computer network technology company. [3] He is one of the creators of the Happy Hacking Keyboard.
The description below describes an all-IBM shop (a "shop" is programmer jargon for a programming site) but shops using other brands of mainframes (or minicomputers) would have similar equipment although because of cost or availability might have different manufacturer's equipment, e.g. an NCR, ICL, Hewlett-Packard (HP) or Control Data shop would have NCR, ICL, HP, or Control Data computers ...
In computing, a keyboard controller is a device that interfaces a keyboard to a computer. Its main function is to inform the computer when a key is pressed or released. When data from the keyboard arrives, the controller raises an interrupt (a keyboard interrupt ) to allow the CPU to handle the input.
Code has been included in the syllabi of post-secondary education technical courses, such as "Fundamentals of Modern Software" where it was called "a little dated, but it is a really clear and incredibly accessible presentation of how computers get from electrical currents flowing down wires to programs you can actually use" [8] and other ...
Logic external to the computer reads the screen RAM memory map segment and updates the virtual screen. If a keyboard is attached to the computer hosting the CPU emulator program, the emulator puts a 16-bit bit scan code corresponding to a key depressed during program execution into the keyboard register at RAM address 24576 (0x6000).
Hardware keyloggers are used for keystroke logging, a method of capturing and recording computer users' keystrokes, including sensitive passwords. [1] They can be implemented via BIOS-level firmware, or alternatively, via a device plugged inline between a computer keyboard and a computer. They log all keyboard activity to their internal memory.
