exploding scope...

As most projects do, they explode in scope once you start thinking more about them. Once I decided that I could have a unified 040/060 socket, I then realized that I could add a cache. The issue is keeping the cost down; however, having 4 megs of cache on a system with 16-megs of memory would be a significant speedup. I will need to look at the cache flushing policies for NeXTStep.
