Die PS/2-Schnittstelle
Seminar : EinChip Computer von Grégory Catellani (2007)
Eine Tastatur ist eine Matrix von Tasten. Diese werden von einem integrierten Keyboard-Encoder überwacht. Dieser registriert welche Tasten gedrückt oder losgelassen wurden und sendet diese Informationen entweder sofort an den Host, oder er speichert sie in seinem 16Kbyte großen Puffer zwischen. Auf der Host-Seite muss sich ein Decoder befinden, der die gesendeten Daten empfängt und verarbeitet. Für die Übertragung der Tastaturbefehle wird ein IBM-Protokoll benutzt. ...

Interfacing a PC/AT-compatible Keyboard by Lee Davison
The connector on the top left of the diagram is from my own 6502 boards and is as it is for two reasons. It's easy to wire on a stripboard layout and I have a lot of 26 way ribbon, headers and plugs. All the signals are directly from the 6502 except /SEL0 and /SEL1 which are used to select the block $F1xx with /SEL0 = 1 and /SEL1 = 0. The 5 pin DIN socket is shown looking at the holes of the socket. ...
