Cobalt60 wrote:Hello everyone, this is my first post. I love collecting older, but interesting, computers. Well, just a couple days ago, I picked up an SGI Indigo for $30! This is my first SGI system, and also my first MIPS system. I believe it is a 100MHz machine, and by looking at the memory, Id guess 160MB (I may have more to add). The graphics board is the Elan!
Unfortunately no hard drive. It only has one drive sled, occupied by a floppy drive. I have 50pin SCSI drives (from old Macs), including a 2GB and 6GB, and planned to swap one in place of the floppy. I also have a few 50pin SCSI internal CDROM drives, as well as various external 5.25" SCSI drives such as SyQuests and the likes. So, I was thinking to swap a CDROM into one of those cases, and hopefully have myself a compatible external CDROM. Also, I have a Sun MicroSystems keyboard and mouse, which seem to fit nicely into the ports labeled 1 and 2, and I was hoping this would work as well.
Well, what I really want to know is what my options are for an operating system. The thing is, Id really like to make use of the 3D capabilities of the Elan board. With this in mind, is my only option Irix? Is there a best version of Irix to run on this machine? Id really prefer to use something open source, or at least free. But if nothing free will be able to use the Elan boards 3D capabilities, I will pursue running Irix. How much does a copy of Irix go for anyway?
Thanks for any help and I am really looking forward to getting this machine operational!

the CDROM, so long as you get the signaling right ... should work - this goes for most everything scsi, but for the best magic-for-your-SGI-bang most here will suggest a Toshiba.
Get a 9GB or bigger SCA drive and use an adapter. All of the 50-pin drives are getting very old.
Not to state the obvious but since SGI's graphics hardware is proprietary to the nth degree no open source driver has ever come close to the performance of the SGi drivers, so you absolutely do want to run Irix....

OK in addition to the standard SCSI drives I have, I also have SCA drives; several are 9GB. Please excuse my ignorance but what adapter should I use?
You'll need an Indigo drive sled if you don't have one, and then use any SCA-> 50-pin adapter. One side of the ID select pins will be common across all three, this is the side that gets the single wire on the ID select pigtail on the sled.
Well, being the SGI noob I am, it was not obvious to me. I knew Irix itself is proprietary, but I was hoping the driver for the Elan was ported to Linux or BSD. Now I know I need Irix to fully utilize the Elan board.
Thanks again for all the help

The only drive sled it came with was one which has a floppy drive installed. It still appears to have a 50 pin SCSI connection, so my plan was to just replace the floppy drive with a SCI hard-drive, and install an OS on it. Sure Id like to get a hold of 2 more drive sleds, but I think I have what I need to get started.
