The PS/2 keyboard port is electrically and logically identical to the IBM AT keyboard port, differing only in the type of electrical connector used. The PS/2 platform introduced a second port with the same design as the keyboard port for use to connect a mouse; thus the PS/2-style keyboard and mouse interfaces are electrically similar and ...

For the keyboard and mouse connectors introduced with this system, see PS/2 port. For other uses, see PS2 (disambiguation). The Personal System/2 or PS/2 is IBM 's second generation [1][2] of personal computers. Released in 1987, it officially replaced the IBM PC, XT, AT, and PC Convertible in IBM's lineup.

Model M keyboards are a group of computer keyboards designed and manufactured by IBM starting in 1985, and later by Lexmark International, Maxi Switch, and Unicomp. The keyboard's different variations have their own distinct characteristics, with the vast majority having a buckling-spring key design and uniform profile, swappable keycaps.

Jul 20, 2016 · If the IBM Model M keyboard is one of the ones that uses the AT protocol, you may be able to use a passive 5-pin to PS/2 adapter, chained with an active PS/2 to USB converter such as the Belkin F5U119.

Jan 23, 2019 · I got got hold of an old IBM Model M (Model 1391403, to be precise). Unfortunately, the fixed cable was cut off by an unknown person, probably to sell it for copper. Does anyone know what kind of connector (I assume PS/2?) was supposed to be at the other end, and what pins the colors correspond to?

2 days ago · The PS/2 (Personal System/2) port, also called the mouse port or keyboard port, was developed by IBM. It is used to connect a computer mouse or keyboard to an IBM compatible computer. The PS/2 port is a mini DIN plug containing six pins and is still sometimes found on all IBM compatible computers.

USB keyboard - Latest keyboard supported by all new computers (Macintosh and IBM/compatible). These are relatively complicated to interface and are not covered in this article. IBM/compatible keyboards - Also known as "AT keyboards" or "PS/2 keyboards", all modern PCs support this device.

Mar 11, 2021 · [Ben Eater] walks us through the PS/2 hall of fame by reverse-engineering the protocol. This is a clocked data protocol, so a waveform is generated on the data pin for each key pressed that can be...

The PS/2 Keyboard and Mouse Interface – p. 10/ ?? Using a PS/2 Port Add lines in the .UCF file about PS2C and PS2D: NET "PS2D" LOC=m15; # Data NET "PS2C" LOC=m16; # Clock Add these ports in the “add cores” dialog. Make the clock pin a falling-edge-sensitive interrupt. In the .MHS file, this appears as PORT PS2D = ps2io_GPIO_in, DIR = IN

The 5-pin DIN keyboard connector used with the first IBM PC (1981) and second-generation IBM AT (1984). It was subsequently replaced with the smaller 6-pin Mini-DIN connector on the IBM PS/2 in...
