We outline the steps needed in order to incorporate the evolution of singleand binary stars into a particular Monte Carlo code for the dynamical evolutionof a star cluster. We calibrate the results against N-body simulations, andpresent models for the evolution of the old open cluster M67 (which has beenstudied thoroughly in the literature with N-body techniques). The calibrationis done by choosing appropriate free code parameters. We describe in particularthe evolution of the binary, white dwarf and blue straggler populations, thoughnot all channels for blue straggler formation are represented yet in oursimulations. Calibrated Monte Carlo runs show good agreement with results ofN-body simulations not only for global cluster parameters, but also for e.g.binary fraction, luminosity function and surface brightness. Comparison ofMonte Carlo simulations with observational data for M67 shows that is possibleto get reasonably good agreement between them. Unfortunately, because of thelarge statistical fluctuations of the numerical data and uncertainties in theobservational data the inferred conclusions about the cluster initialconditions are not firm.
