The Ports/mac68k/ webpage doesn't list Powerbook 520 or 540c as supported
system models, but I have found postings about using them so I assume they
are supported.

I have found a cheap 520 and 540C (with MacOS 7.6 installed).

I read that the 520 is 50Mhz and the 540c is 66Mhz. But I don't have
experience with them, so I don't know much about their performance.

(My Intel 486-66 boxes not running X work just fine. My Intel Pentium 166
workstations running X work great, but my Intel Pentium 120 laptop is
very slow.)

What would something like a 520 or 540C compare with (performance) in the
Intel i386 world?

It would be nice if X can run okay for doing presentations (via LCD
projector plugged into external monitor port).

I am curious: for someone who has never installed NetBSD on a Macintosh,
but has installed it on i386 well over one hundred times, any ideas on how
long it will take to install (not counting download time)?

(Please CC me when responding.)
