133MHz R4600.  Okay integer performance, dinky floating-point

8-bit unaccelerated graphics.

Yay for that.  Those little pieces of aluminium are worth their weight
in gold.

Much nicer than the R4600. :)

Well, plain ol' parity will work fine, so long as it's not that "logic
parity" crap that some PCs had back in the early 90s.

Either 32MB or 64MB.  Install the SIMMs in matched sets of 4.

Maybe, maybe not.  It will work on some of the later monitors, but
nothing made before about 4 years ago.  However, any sync-on-green
monitor will work just fine.

Entry-level.  It'll do 1280x1024 at 8-bit color.

The best video you can get is XZ.  The fastest CPU is R5000 @ 180MHz,
and the memory maxes out at either 256 or 512.  I can't remember.

Don't worry about parts being unobtanium.  SGI sold a -lot- of Indies,
and they're all over eBay.

> Can I digitize incoming video ?  What software would be required ?

It's included.  Indy has VINO video (Video In, No Out).

That's the IndyCam port.

Nope.  Look closely.  It's actually on a riser above the system board.

> I see a 1 and 2 port (are these serial?)

Yes.  RS-422, like a Macintosh.

You also apparently missed the ISDN port! :)

> I assume the box is Fast SCSI (10MB/sec max) and uses ordinary SCSI disks ?

Fast/Narrow SCSI-II.  Most discs will work just fine.

IRIX 5.3, 6.2, and 6.5 work just great.

Friends, eBay, or SGI (ouch).

Yes.  However, the Indy properly sends the SCSI command to kick some
drives into 512-byte mode without a jumper.

> Is there a max capacity hard disk ?

Not really, but you don't want to put hot discs internally.  The Indy
doesn't have the world's best airflow.

Yeah, well, it was billed as a PC replacement.  Don't judge all SGIs by
the Indy.  You'd be suitably impressed by an Onyx IR, I think.
