I’m looking for a good free reference (online book, list, article, chart, etc – source must be reputable) that will list various OS’s and the minimum CPU required for running them.
This needs to cover from MS-DOS 1.0 to 6.0, first MacOS, Windows3.0 to 2000. If a reference covers at least two specific OS’s listed above (for instance, MS-DOS 1.0 and 3.0), the answer will be accepted.
