Thanks for fixing that longstanding typo. But wow, IRIX? SGI itself stopped
supporting IRIX in 2013.

Do you have a computer museum in your attic? In the late 1980s I unwisely
accepted an old PDP-11 that rested in my garage until I threw it away. I had
been thinking of running 7th Edition Unix on it, just for fun. But it was a big
and heavy clunker and I never even powered it on.
