Oh, the nostalgia...(disclosure: worked at Sun in the mid 90s)
I had a Sun SparcStation 20 in the mid 90's at work. I was some discarded equipment that nobody was using, that was just laying in a corner somewhere. I put Red Hat Linux 2.0 on it from a CD-ROM. I put a TFTP server on it, and used it as the server for booting an NCD X/Window terminal. Also something nobody gave a shit about. I had GIMP running on it; at some point, people gathered around the cube to see that. Being…
We got a few Ultra 2 machines and then an Enterprise 450. I still remember being so excited when it arrived on a palette and when we unboxed it it came with 2 wooden ramps that attached to the palette so you could roll it down to the floor.
One engineer got an Ultra 60 as his desktop but by 1998 we started replacing most desktop machines with Linux / x86 and running everything remote and displaying to our local machines via X11 with the Suns in the closet. We also had a Sun Enterprise 4500 with around 16 CPUs at the main office.
By 2003 we started replacing our Suns with AMD 64-bit machines and Linux. All of our semiconductor design software was already Unix / X11 so it was easy to port to Linux. Around 2004 the switch was complete and we never used Suns anymore. They just fell behind the price / performance curve and couldn't compete with Linux / x86-64 anymore.
