The collected works of PowerGraphics

I have an Indy R4400 200MHz 32MB RAM IRIX 6.5.22 , with an HD 1Gb , and would fit in place of the HD, a memory card 4GB connected using a USB adapter on the SCSI connector that plugs right into HD .

A SCSI to USB adapter is possible? What adapter would be recommended ?

The SCSI rear back of Indy is equivalent to the SCSI connector connected directly to HD ? If I plug a SCSI adapter on the back of Indy would mean the same ?

I would like to install all the software on the card , by the Indy manager software because the HD is full limit with the operating system installed , and every time I need to install other software , I have to uninstall another program .
I have a Indy R4400 200Mhz 8bit XL graphics, 1GB HD, Irix 6.5.22.

I am analyzing the Xservers file in the /var /X11 /xdm, made the change indicated for systems with 24bit video of the original:

:0 secure /usr/bin/X11/X -bs -nobitscale -c -pseudomap 4sight -solidroot sgilightblue -cursorFG red -cursorBG white

changing this line to:

:0 secure /usr/bin/X11/X -bs -nobitscale -c -solidroot sgilightblue -cursorFG red -cursorBG white -depth 24 -class TrueColor

But the result is not being as expected, that is, the colors are still making dithered.

When using the program xli the result appears to be correct, but I intend to get a result in all full desktop system.

An important note: is that I got an excellent result doing something similar using irix 5.3 in more than 15 years ago, but lost the configuration file, and I can not remember exactly what was done.

Curiosity: On another note, the official technical description of silicon graphics on the indy 8bit XL, says it's possible to make truecolor in this system, called "virtual 24bit".

So I believe it is possible to do the same using irix 6.5.22.
Possible is doing dithering or not, I know that was possible when I wore irix 5.3! This is true!
I managed such a feat, but I lost the configuration file to 15 years.
If only it is possible using dithering, so what should write in Xservers file then?
How to configure the virtual 24bit using my 8bit XL system in IRIX 6.5.22, or in IRIX 6.2 or in IRIX 5.3. This is only possible using IRIX 5.3?

I'm not disagreeing with anyone here. I sincerely believe in you guys. I just said I could make it work, even if it is apparently on IRIX 5.3, and the colors seemed very clear and smooth, when you use the standard 8bit mode. But I lost the settings to 15 years ago.
Anybody have the program, and have the possibility of the dispose to me for download?
If I understand well, all I need to do to my system supports 24bit (dithered or not), it would be put in the Xserver file, only the command -depth 24, and nothing else, not even put -class TrueColor (or PseudoColor or DirectColor), is this?
Exists any software for PC Windows that is possible make videoconference with a Inperson running in a Indy?
