It had real time I/O. It had the best user interface at the time, with super fast scalable vector graphics for everything in '94. (Modern desktops have caught up some 13 years later). It had usable 64 bits everything before anyone else - R10000 was generally available in '95.
They were insanely fast compared to the Sun and Digital stations of the time - the only competitor was Digital Alpha, and IRIX beat Ultrix to the ground and mopped the floor with it.
These were the days of multiculture, where my employer insisted on having several Alphas, Suns, SGIs, RS/6000 and more to make sure we're not locked to any specific vendor.
