THE 64-BIT workstation market has been kind of quiet in the past two years. Why? Well, on one side, Pentium/Xeon 32-bit systems took over the bulk of mainstream 3-D workstation market, and on the other side, some of the key 64-bit workstation platforms that could be called performers (that excludes Sun, of course) were on decline – Alpha, SGI, PA-RISC, pick your choice.
