Q: Name the one thing that Classic Computers have that modern computers lack? A: Adequate documentation to write your own system level software on them! What we need is the "Open Hardware" movement. What is Open Hardware? It is a set of specifications for a computer and an interface system that anyone can build processors, I/O, or accessories for without owing any taxes to anyone. However, ideally, this "open architecture" needs a bit of software already available for it to get the movement off the ground. I suggest that the PDP-11 could be that architecture for several reasons: 1) It has lots of software available for it. 2) It can be expressed in a single modern FPGA so processors can be "home built" 3) It has some pretty easy to use busses defined for it (Q-Bus, Unibus) Alternatively one could go with something like SPARC (which Sun alleges is open but I have my doubts) Comments? --Chuck
