SPARCstation 20

It's mostly the same as the SPARCstation 10 inside,use the Aurora (similar to SPARCstation 4/5), but has some extra features.  It's normally a decent workstation still today allthough a lot of things depend on the exact configuration. The SS20 can go from 40 to 200Mhz (with Ross Hypersparc Modules), 1 to 4 processors and 16 to 512 MB RAM. The difference between a low end and a high end configuration of one single workstation is impressive.My worksation is not original at all, because i used two SPARCstation 20 and one SPARCstation 4 (for Aurora case) to build this one. But the final result is a perfect regenerated single SPARCstation 20.
