Looking for FreeBSD 4.7 ISOs

I’ve been meaning to do this for a while now, and now that I have some room on my laptop I want to create a FreeBSD 4.7 VMWare image so that I can show Rotor’s cross-platform nature (such as it is). But, to make a long story short, I can’t find the ISO images for FreeBSD 4.7. I can find 4.9, 4.10, 4.11 (none of which are officially supported by Rotor) and of course the latest 5.3/5.4 images, but not 4.7. Anybody happen to know where I can find archive releases of FreeBSD, so I can download them?

That, or teach me how to Google better…. 🙂
