Chronology of what was authored in the year, 1994
For high-end computers for everything from graphics workstations to web servers, this was my advice as a former CAD consultant and Unix systems adminstrator.
The specification details, of course, changed over the years, but the general approach and core technologies remained the same for those six years.
e.g., Look for features which you know you’ll need within one year; Only get gear which may be upgraded; Consider the CPU as disposable; etc.
