Yeah it was. And back then, running IRIX, I was more than a bit crazy and wild. It was such a fun OS! SGI as mentioned up thread, put a ton of thought into it.

Once a person reached a solid mastery, amazing things could be done, sans reboots and the like.

I was terribly spoiled though. Ran it until it made no sense, then ditched all of it to go small.

My next fun toy was the Parallax Propeller. The first chip was amazing, 8 cores all independent. It was a full multiprocessor, able to perform concurrent and or parallel computing with such ease! Spoiled again!

The second chip is the Amiga of microcontrollers. Maybe I could call it the SGI of micros. Today, one can program the 8 cores in BASIC, SPIN, C and ASSEMBLY, all at the same time!

Write video driver in assembly, framework in SPIN, some functions in BASIC, others, maybe sound in C.

It has hardware support got ADC / DAC and more on every pin, shared CORDIC math able to do powers, roots, trig and more. It can drive almost any display made since monochrome TV.... too much fun.
