The Goal: Describe the optimal computer.
Fair Assumptions: Unlimited funding. The computer need only be capable of calculation - specific traits, such as AND gates, are not necessary. Assume that simply housing a computer in an alternate dimension is not possible.
Parameters: Access to any level of technology described in SA. The winning entry will likely be the fastest computer, but credit will also be given for particularly interesting methods or for computers that are easily portable.
Entries can be read in the Forum. Further entries are still welcome - it's always fun to see new ideas.
