The KIM-1, short for Keyboard Input Monitor, is a small 6502-based single-board computer developed and produced by MOS Technology, Inc. and launched in 1976. It was very successful in that period, due to its low price (thanks to the inexpensive 6502 microprocessor) and easy-access expandability.

For example, 1280×1024 (5:4) or 1360×1024 (≈4:3) in 16 colours at 60 Hz, 1056×400 [14h] Text Mode (132×50 characters); 800×600 in 256 or 64k colours; and even as high as 1600×1200 (at a reduced 50 Hz scan rate) with a high-quality multisync monitor (or an otherwise non-standard 960×720 at 60 Hz on a lower-end one capable of high ...
In 1984, IBM's EGA added a second resolution which necessitated the use of a monitor supporting two scan rates, the original CGA rate as well as a second scan rate for the new video modes. [5] This monitor as well as others that could be manually switched between these two sync rates were known as dual-scan displays.
A further complication is that a device traditionally considered an input device, e.g., card reader, keyboard, may accept control commands to, e.g., select stacker, display keyboard lights, while a device traditionally considered as an output device may provide status data (e.g., low toner, out of paper, paper jam).
On the 84-key AT keyboard these were largely a subset of set 3, with some differences caused by the revised layout (for example, the position and scancodes of the function keys changed). Keys added since the PC AT often have different scancodes in set 2 and set 3, and in set 2 frequently have an E0 or E1 prefix.
At the conclusion of its seventh and penultimate rate-setting policy meeting of 2024 on November 7, 2024, the Federal Reserve announced it was lowering the federal funds target interest rate by 25 ...
In computing, the USB human interface device class (USB HID class) is a part of the USB specification for computer peripherals: it specifies a device class (a type of computer hardware) for human interface devices such as keyboards, mice, touchscreen, game controllers and alphanumeric display devices.
