Examples in Actual Computer Systems
Cycle stealing has been the cause of major performance degradation on machine such as the Sinclair QL, where, for economy reasons, the video RAM was not dual access. Consequently, the M68008 was denied access to the memory bus when the ZX8301 was accessing memory, and the machine performed poorly when compared with machines using similar processors at similar speeds.
Cycle stealing was also the cause of errors reported by the Apollo PGNCS of the Apollo Guidance Computer.

Famous quotes containing the words examples, actual, computer and/or systems:
“It is hardly to be believed how spiritual reflections when mixed with a little physics can hold people’s attention and give them a livelier idea of God than do the often ill-applied examples of his wrath.”
—G.C. (Georg Christoph)
“Our ideas are the offspring of our senses; we are not more able to create the form of a being we have not seen, without retrospect to one we know, than we are able to create a new sense. He whose fancy has conceived an idea of the most beautiful form must have composed it from actual existence.”
—Henry Fuseli (1741–1825)
“The computer takes up where psychoanalysis left off. It takes the ideas of a decentered self and makes it more concrete by modeling mind as a multiprocessing machine.”
—Sherry Turkle (b. 1948)
“Not out of those, on whom systems of education have exhausted their culture, comes the helpful giant to destroy the old or to build the new, but out of unhandselled savage nature, out of terrible Druids and Berserkirs, come at last Alfred and Shakespeare.”
—Ralph Waldo Emerson (1803–1882)
