Some years ago we used a program called PML to do Rasch analyses:

Gustaffson, J.-E., PML: A Computer Program for Conditional Estimation and Testing the Rasch Model for Dichotomous Items. Reports from the Institute of Education, University of Goteborg, 85, 1979.

I think we got it from IEC ProGamma, so I tried and there I found: MSP 3 W. Molenaar, University of Groningen, NL P. Debets, University of Amsterdam, NL K. Sijtsma & B.T. Hemker, Vrije Universiteit Amsterdam, NL MSP, Mokken Scale analysis for Polytomous Items, offers scaling facilities for the nonparametric cumulative item response theory. The program can be used for the stepwise construction of one or more unidimensional scales from a pool of items. It evaluates the model fit of a given scale, including the assessment of its reliability and gives suggestions to remove certain items that spoil the fit. Also, it detects the extent to which the answer patterns follow the cumulative Guttman scalogram pattern, for an item order found from theory or from the data, by Loevinger's H-values, with statistical significance tests added. MSP is able to analyze and compare several subgroups in one run, and performs various tests and checks of the assumptions of monotone homogeneity and double monotonicity, underlying the models.

I hope this will help.
