SGI Indigo
Whoa, Mark brings back some old memories.
The Indigo was a beautiful machine. My daughter would approve of the colors, and my subconscious still associates the machine with pure speed and power. It was so beautiful that I could ignore the proprietary compiler and window manager annoyances. A machine that expensive seems ridiculous today, but it was sooo fine!
If you have an old Indigo lying around, donate it to Mark’s museum. The Vintage Mac Museum on the Scoble Show was cool, but a “Vintage Unix Workstation” museum is better.
