SGI Keyboard

Keyboard: http://www.sgistuff.net/hardware/other/input.html

Protocol: https://web.archive.org/web/20151124154027/techpubs.sgi.com/library/tpl/cgi-bin/getdoc.cgi%3Fcmd=getdoc&coll=0650&db=man&fname=7%20keyboard

Connector: https://hardware.majix.org/computers/sgi/keyboards.shtml

The interface between the keyboard and the system is 600 baud asynchronous. The format used is one start bit followed by eight data bits, an odd parity bit and one stop bit, with one byte sent per key up or down transition. The MSB of the byte is a 0 for a downstroke and a 1 for an upstroke.
