Keyboard and Mouse
The Power Series family uses a DB15 serial keyboard connector with the
same specifications as the Professional Series family. Indeed, by
wiring up an appropriate adaptor cable, you can use any of the SGI
proprietary keyboards (SGI #950-0801-xxx) with the Professional,
Power, Personal IRIS and Indigo series machines. The same goes for the
mouse, which simply daisychains off of the keyboard. For more
information, check the chapter in the /*Professional Series*/ section
of this document entitled Keyboard and Mouse

Mini-DIN-6 keyboard connectors are found on Indigo,
Indigo2, Indy, O2,
Octane, and Onyx systems. This pinout is for Indigo systems which _is
not_ P/S2 compatible. The pin assignments for the Indigo keyboard
connector are shown in the following table:

Older SGI systems used a DB15 connector for the keyboard and mouse,
with either a DIN6 or DB9 connector at the keyboard end. Here's the
pinouts for the DB15-DIN6 cable:

And here's the pinouts for the DB15-DB9 keyboard cable:

SGI P/S2 Keyboard and Mouse to RJ45 plug, using (2) mini-din6
connectors to (1) RJ45 plug.
Use to extend mouse & keyboard connections with RJ45 cable. ONLY for
SGI systems that have P/S 2 compatible ports (Indy, Indigo2, O2, etc).
This is a "Y" cable; two mini-din6 connectors are wired to one RJ45
plug. A pair of adaptors is needed, one mini-din6 female set, and one
mini-din6 male set. Custom made by Anixter 408/435-1212, but SGI I/S
stocks them internally- contact alex(a)csd.sgi.com. $20.75 each, so pair
is $41.50. Mark Aubin aubin(a)asd.sgi.com

However, by making a conversion cable you can use
any sgi -/+12V keyboard/
mouse using an EIA-232 interface. I've done this for my 4D/25 and it works
great. Any of the Single Tower, Twin Tower or Predator (Case types)
keyboard/mouses will work; i.e., Crimson, etc.
Interesting. I've only worked with Origin 200/2000 SGI machines so don't
know much about any of the older systems or the desktops.
Any idea if an Indigo keyboard is compatible? Reason I ask is that the
guy who's disposing of the machine has found a website describing a
convertor to allow a stock PS/2 keyboard and mouse to be used with an
Indigo.
If the 4D can use an Indigo keyboard then it should work with this
convertor, which would be a start...
cheers!
