Comparing two microcomputer operating systems: CP/M amd HDOS
Abstract
Two moderate operating systems are compared, with the intent to demonstrate how each may satisfy the needs of a different set of users. The clear superiority of either systems does not emerge, but rather a difference in “design philosophy.” A method for comparing other similar systems is demonstrated.
