AbstractThis note discusses experiences in running discrete-events simulation models on an Apple II microcomputer. The use of PASCAL as a simulation language is commented on. To give an indication of the type of simulations that can be run on a micro, a fairly complex model relating to icebreaking operations is discussed. Run times for this model are mentioned. It is indicated how those run times can be reduced by programming part of the random number generation in assembly language. The conclusion is that significant simulation work can be done on a small micro like the Apple II.
