Well, seems that now is my time...
I have the oportunity of - at least - putting my dirty hands into a
SGI
indigo! :oD
My questions:
- How fast is it?
- What can I run on that?
- Does it use any kind of special memory?
- Can I use a PC mouse/keyboard with that?
- Are the monitor frequencies suitable for a modern PC monitor?
Thanks
Alexandre
(yes, in Brazil these are R A R E !)
It really depends on the version of Iris Indigo you have. They come in
various flavors from the above mentioned R3000 to an R4000 version that can
support the R4400 up to 150mhz. The R3000's do require special ram while
the R4000/4400 use standard 72 pin SIMMS. All Iris Indigo's need the
special keyboards (9500801 Indigo Keyboard (beige), 9150800 Indigo Mouse
(beige)) or the PS2 adapter you mentioned. They also came in several levels
of graphics sophistication from the LG1/2 Entry boards to the Elan with 4
Geometry Engines, 24bit video memory and a Z buffer.
The R3000 units will run Irix to 5.3 with XFS and the R4400 wil run up to
the R6.5.2x versions. Support for the Iris Indigo was dropped from Irix
above 6.5.22 as I recall. But at 6.5.22 you can run most freeware and
commercial software.
Omne thing to keep in mind, the tOD battery will probably be dead in your
Indigo. Some are soldered on the motherboard, some are plug in. The
proper part number is a Tadiran TL-5186.
If you find a keyboard and need some odd bits, let me know as I have 8 Iris
Indigo's and a couple of bins of spare parts. I also have some Sgi freeware
on my ftp server at blackcube.org.
