Hi Hey People, It was a joke ! Or, to better say, a provocative question ! But to be serious: there are people who program exotic things on a Playstation. For example he at the ETH Zuerich (Switzerland, look at www.ethz.ch) the is a job for a semester offered to implement Oberon at Playstation. I don`t know how the Playstation works at all, so I can`t say what kind of projects are possible there. maybe in about 10 years, when my toaster has an advanced chip inside it, it can doublecheck some old results ... see ya Bojan > > Sony Playstation has got a MIPS.
