To get the latest version of dvips, simply get the latest version of teTeX or some other TeX distribution that includes dvips. For a list of distributions, start at TUG. I no longer support installation of dvips independent of full installation of a TeX distribution.
If you are visiting this site because you have a file that starts with %!PS and you don't know how to print it, I recommend you download Peter Deutsch's excellent GhostScript; it will make you exceedingly happy.
More on dvips is available here.
AmigaTeX is no longer available.
My doctoral thesis on timed circuits might be interesting to some; the code itself (called Orbits) is no longer available.
