It could be made ROM from the program point of view (i.e., > it's loaded from the user interface but the CPU can't store there). And has already been done for the VAX; even simulation of the slower ROM speed. _______________________________________________ Simh mailing list Simh@trailing-edge.com http://mailman.trailing-edge.com/mailman/listinfo/simh
