I'd be making your copy. The Wayback Machine is now disallowing the most recent archived version (2009) presumably at Clay's request - if so, he's really taken the ball this time!!

User-agent: *
Disallow: /wpc/
Disallow: /bally/
Disallow: /em/
Disallow: /pin2000/
Disallow: /6803/
Disallow: /sys1/
Disallow: /sys3
Disallow: /sys80/
Disallow: /sys37/
Disallow: /sys11/
Disallow: /de/
Disallow: /gp/
Disallow: /restore/
Disallow: /cgi-bin/

Only a matter of time before he gets that version removed too.
