Indigo2s

NB: I will be unable to process item requests from 03/Jun until 18/Jul.

Last Change: 07/Jun/2022

NOTE: I can provide hardware support and parts/spares for STOLL SIRIX systems!
I have numerous Indigo2s available, far too many to list individually, so here are some example configurations. Choose the one closest to your needs, then add on any extras or discounts as required. See after the table for full details.

NOTE: XL24/SolidIMPACT use 1 slot,
      XZ/Elan/HighIMPACT use 2 slots,
      Extreme/MaxIMPACT use 3 slots.

NOTES:

#1: An example number-crunching system, ie. best possible CPU, good RAM with
    room for expansion, reasonable disk, but cheapest possible graphics.
#2: R8K systems are not as fast as R10K systems for integer tasks, but are good for certain
    fp tasks and are fascinating to work with. Ideal for compiler fans.
    The max RAM for an R8K system is 640MB, whereas the max for an R10K system is 1GB.
#3: XL24 is good for 2D tasks (much higher 2D fill rate than the non-IMPACT 3D
    options), eg. for use with Indigo2Video, CosmoCompress, etc. Also good for
    better expansion, eg. dual-head XL24, 10/100, video option, etc. The XL24
    board PN is 030-8202-004.
#4: The R4600SC/133 has the same integer performance as the R4400SC/175 and thus is much faster
    than an R4400SC/100. It is though also a very rare CPU, hence the cost.
#5: This config is present just to show that using 128MB kits in R8K/R10K Indigo2s is not optimal,
    because a single 256MB kit is cheaper than two 128MB kits (the latter are more expensive
    per MB because they are the best possible kit for Indy, and thus distorted by Indy demand).

These configurations are not fixed. I can upgrade/downgrade as required.
Use the upgrade pricing tables below or price differences above to calculate
other combinations, or feel free to email me if you're interested
in a configuration not shown.

For an extra disk with sled, select the required SCA disk from the SCSI Disks Table and add
the cost of a sled (original SGI sled recommended, the 3rd party types are not very good).
Indigo2 can have two internal disks, though it's possible to fit a third using a CDROM sled.

For a full list of available upgrades/extras, please see the Parts/Spares page, including having better condition top lids, etc.

Please see my 2nd-hand Indigo2 Buyers Guide for complete background information on Indigo2.

See the shipping costs page for details of postage charges to the UK, mainland Europe and beyond..

All systems have some degree of scratching on the top lid, but are always fully intact (no broken catches, etc.) If cosmetics are important though, then I can fit a system with a good condition lid for extra, or indeed I could do a discount if you don't mind a top lid with a broken catch, etc. Note though that just now I do not have any good condition purple top lids.

All Extreme systems have an Extreme badge, all IMPACT systems have an IMPACT badge, and all R10K systems have a 10000 badge. Any complete teal system valued more than 500 UKP comes with teal footstands for free.

All Indigo2s include a metal locking bar and power cable (assuming I have the right type of power cable). Original SGI keyboards/mice are available separately, or I can include a new generic black PS2 kybd/mouse set for +20. Any 6.2/6.5 system valued at more than 500 UKP also comes with my custom SGI Nekoware and Gifts CDs. See the IRIX CDs page for details of these CDs. Alternatively, I can include a full 6.5.22 CD set for +80, or +65 for non-IMPACT systems (email for details). Monitors and monitor cables are also available - see the monitor section.

By default, all systems with at least 256MB RAM come with a full IRIX 6.5.22m installation - the last version of IRIX released for Indigo2. My installation includes lots of extras such as Blender, BMRT, Ayam3D, mplayer, OpenOffice, Freeware/Nekoware, Quake, Quake2, etc. Adobe Premiere 4.2 is also installed on IMPACT systems, plus many other items, including a good custom desktop layout. A typical installed software list in Software Manager looks like this. Note that I can install 6.5.22 on a system with less than 256MB RAM, but it won't run quite so well (128MB is viable if one isn't doing heavy tasks, but really it should be 256MB or more for smooth running). I can install 6.2 or 5.3 if prefered though and it's certainly true that 6.2 on (say) an R4K/200 Extreme will feel a lot snappier than 6.5.22m (one would of course just be limited by the older versions of various programs for 6.2).

All systems with less than 256MB RAM by default have a good IRIX 6.2 installation, including the patch updates and Y2K fixes. Such systems come with the May 2001 Freeware CDs included (the last freeware release which fully supported 6.2) and my May 2001 Gifts CD. Alternatively, I can include a full 6.2 CD set for +40, email me for details).

Lastly, not everyone wants to have the latest OS, or perhaps an earlier version is needed anyway. Thus, if required I can also install older releases such as 5.3 with XFS, 5.2, etc. on any configuration that can take it.



Graphics Comparison Summary

For full details on Indigo2 graphics options, see my 2nd-hand Indigo2 Buyers Guide. The following description is just a summary.

GR2-XZ graphics (2 Geometry Engines [GEs] and 1 Raster Engine [RE]) is generally half the speed of Elan graphics, although it can actually be very similar if the bottleneck is pixel fill instead of geometry processing. Elan is half the speed of Extreme, ie. Indigo2 Elan graphics is the same speed as 'Indy XZ', which is also the same as Elan for IRIS Indigo (4 GEs and 1 RE).

Extreme graphics, with 8 GEs and 2 REs, is about the same speed for shaded/wireframe/points tasks (ie. anything non-textured) as an R5000SC/180 O2 and is thus quite good for using animation packages such as Blender. Here is a comparison table:

                                        Lit Gouraud Z
           GEs    REs     MFLOPS (**)   Triangles/sec     No. Slots Used
           ^^^    ^^^     ^^^^^^^^^^    ^^^^^^^^^^^^^     ^^^^^^^^^^^^^^

Extreme:    8      2         256            405M                 3
Elan:       4      1         128            181M                 2
GR2-XZ:     2      1          64            100M                 2

(**) Available MFLOPS processing power for accelerating
geometry/lighting calculations (32MFLOPS per GE).

For precise real-world examples, see my Inventor benchmark results. Compared to the original XZ/Elan/Extreme graphics, IMPACT options use later GE and RE designs such that SolidIMPACT (with 1 GE and 1 RE), is up to twice as fast as Extreme, can do 32bit colour (Extreme cannot) and only uses one slot (Extreme uses three), although Extreme is quite strong for wireframe tasks (IMPACT focused more on improving shaded performance and adding hardware texturing). SolidIMPACT is good for non-textured tasks, and has other benefits and improvments compared to Extreme.

HighIMPACT graphics is the same as SolidIMPACT for non-textured tasks, but it includes hardware texture mapping with either 1MB or 4MB texture memory (TRAM) and so is much faster for textured tasks (typically 20X to 50X faster - the more complicated the scene, the better the speedup compared to software texturing). A 1MB TRAM system is limited to 16bit colour, while a 4MB TRAM system can do 32bit RGBA double-buffered or even 36bit RGB for high quality imaging. IMPACT graphics also supports higher resolutions than the older graphics. There is a rare version of HighIMPACT called HighIMPACT/AA - this has 2 GEs but still 1 RE, but note it is the same speed as ordinary HighIMPACT - the AA version merely used a temporary alternate GE design. HighIMPACT is a good entry choice for playing games such as Quake, Certain IMPACT, Mekton, etc. properly (definitely best with 4MB TRAM), but also offers hardware accelerated 2D imaging and other benefits.

MaxIMPACT is up to twice as fast as HighIMPACT for everything (2 GEs and 2 REs), supports even more resolutions, and also has either 1MB or 4MB TRAM. See the Inventor 3D results for High/Max comparison examples - examine the data for the Underwater Camera, Huge Engine and Chromeskins models. NOTE: these tests only use one texture, mapped onto a whole model (environment mapping). A model which consisted of lots of separate textures mapped in the normal way would show a larger difference between High and Max, and a similarly larger difference between software and hardware texturing.
