A BIG SGI IRIS, I think it was a 3000, but it looked
even larger than
pictures I've seen of those.
Quick check on those: was it beige? The IRIS x000 series were the only beige computers SGI
produced.
If it was brown it's a 4D.
They made them in 3 sizes, I've seen 2 (terminal and deskside)
The terminal could sit on your desk. 9 Multibus slots, no disks
The deskside is the most common- 20 Multibus slots, 2 5.25" FH HDD positions and 1
5.25" FH removable-media position, along
with much dead space. Stands about 3' high.
There are rumors of a rackmount designed to use SMD drives, for those who needed big, fast
storage.
There are a number of people on the list with these, if you're interested grab it.
