Being the kind soul he is, Michael first provided the rd.net community with this collection of empirical V1 test results. Needless to say, this is a wonderful thing to have.
This thread serves as an alternate location for that information as well as a placeholder for future results. Early RX65 information is at the end of that thread, as well.
I'd imagine that this has been mentioned here and there on the forum, but I would imagine that we have several members here that would be willing to part with their more recent RX65, rev3 / 5 8500 x50, or 3.851+ Valentines for further testing assuming that we have someone to test them. So, to Michael or anyone else with access to the appropriate equipment and willingness to do some good testing: how about it? I have a rev3 X50 that I may be able to send off if nobody closer to you could do so, and I'd think that others here may be able to provide equipment, too.
