I've read that I need 256Mb RAM, or 384Mb for the Live install and elsewhere read that EMC2/Ubuntu runs on x86 but need confirmation that it will run on a 486 box - yes they still exist, this one is doing stirling service running Windows ME, but is about to get redeployed as machine controller for my soon-to-be-constructed PCB router. Before I go down this route I'd like confirmation that this PC will be suitable as so much software these days says x86, but they really mean Pentium class!
