A long time ago Futuremark made available for free at their website the benchmarks that were no longer supported. This included both the 3dmark series and the PcMark series complete with addons and serials. As of today, November 27 2020, they are no longer available. I did grabbed copies of 3dmark series: 99, 2000, 2001, 2003, 2005, 2006, Vantage, 11 but I do not have any copy of the PcMark series. Did someone who downloaded them can make them available? They are free for personal use so this should not be a problem.
