Hi all,
Any ides if the keyboard and mouse needed for an SGI 4D/25 was used on
any of SGI's other models?
A machine just cropped up for free but it's got no mouse or keyboard
with it. The keyboard socket on the machine is a 9-pin D-type female
(umm a B-type in correct terminology I think) - I'm assuming the mouse
plugs into a port on the keyboard, rather than tying up one of the
serial ports on the machine?
Oh, the root password isn't known either... but I'm assuming there will
be ways around it on a machine this old.
cheers

Here are the pinouts for the DB-9 Mouse/Keyboard Connector. The connector on
the DB-9 is unique to the 4D/25 and is not replicated on any other SGI model.
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.
Pinouts:
1 N/C
2 KRCD - Keyboard receive data - input
3 N/C
4 -12V DC - Power
5 MRCD - Mouse Receive Data
6 GND
7 +12V DC - Power
8 KTXD - Keyboard transmit data - output
9 GND

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...

From "this Old Sgi"
http://www.geocities.com/SiliconValley/Pines/2258/4dfaq.html#pwrkeyboard
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
<http://www.geocities.com/SiliconValley/Pines/2258/4dfaq.html#keyboard>.
From "Chan's Pinout Page"
http://www.meadow.net/pinouts.html#sgikeydb9
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:
------
/ 5 3 \
| --- 1 |
| --- 2 |
\ 6 4 /

Pin Assignments

1 | KRCD Keyboard Receive
2 | MRCD Mouse Receive
3 | GND Ground
4 | Power +8V
5 | KTXD Keyboard Transmit
6 | Power -8v
------------------------------------------------------------------------
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:
DB15 Male DIN 6 Signal/Signal

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

You can use the Indigo keyboard. I'd modify the adapter to use a "d"
series connector instead of the mini-din the site shows. In fact there
is a guy selling assembled and tested adapters on ebay. I've had good
luck finding the Indigo keyboards in a couple of surplus stores that
deal with "PC" parts. The Sgi keyboards get thrown in the junk bins
because they don't come with a cord attached and the employee's are too
lazy to look for a din6 m-m cable. It's a good thing too, because you
will kill the keyboard plugging it into a PS2 port and since they are
untested, I usually pay under $5 for a keyboard. I haven't found a dead
one yet.
As for Indigo mice, I've bought two bulk lots of used Indigo mice from
ebay in the past few months. I paid around $15.00 for 6-8 mice in
each. Most worked. I've adopted a lot of Indigo's recently. I think
I've got 8 up and running so far.

Sweet. I think I forgot the actual site address from the original post,
so for the curious (and archies) it's here:
http://rshockley.dyndns.org/indigo.htm
Perhaps the same chap who's selling them on ebay.
I've had good luck finding the Indigo keyboards in
a couple of
surplus stores that deal with "PC" parts.
They seem to be a little more hard to come by on this side of the pond;
in fact all SGI stuff does. I remember talking to a couple of SGI
employees when I was using their machines for projects a couple of years
ago, and they were most annoyed that anything obsolete coming in as part
of upgrades etc. from customers was crushed.
Sounds like I can get things up and running with a PS/2 keyboard for
now. I'll give you a yell about the surplus mouse that you mentioned if
a suitable keyboard crops up.

If you have an IRIX 5.3 install set, you can easily boot from the install
CDROM, bypass the install, gain root control and change the root password to
anything you like. If you don't have an IRIX 5.3 install CD, you'll have to
do some serious hacking as IRIX by 5.3 was reasonably good on security. Of
course, someone may have used a simple password and made "guessing" an
option.
BTW: If you get this ol' critter running, you'll be impressed by it's graphics
capabilities considering it's vintage (especially if you have a higher end
graphics set). This is especially true for 2D - but 3D is SLOW because the
PI didn't have texture memory as on option.

AFAIK all the 4D models used the same
keyboards. Some of the later machines (4D3x, Indigo) used a PS/2 style 6 pin mini DIN
connector at the machine side.
I'm assuming the mouse plugs into a port on the
keyboard, rather
than tying up one of the serial ports on the machine?
Yes, the mouse gets pluged
into the keyboard.

I found a PI mouse at a surplus store for a buck. If you want it, reply
off list. I think I paid a buck, so you could have it for postage.
