I was looking through my closets and realized I have four 486 computers (an SX and three DX2s). I've decided I want to cluster them this weekend. However, what is a good distro that will operate on that era of hardware (assume 8mb ram max) and comes out-of-box with 2.4 kernel support? I have a P1 100mhz w/o mmx if I need to use it in the cluster, though I hope to install NetBSD on it. Thoughts? Comments? Suggestions?
