These include simulators for the IBM 701, IBM 702, IBM 704, IBM 705, IBM 705/3, IBM 709, IBM 1410/IBM 7010, IBM 7070, IBM 7080, IBM 7090 and IBM7094. These basically were a collection of machines that shared a common set it peripherals, Each group had its own instruction set, hence different simulators. IBM 701 -> i701 IBM 702/705/705/3/7080 -> i7080 IBM 7070/7074 -> i7070 IBM 1410/7010 -> i7010 IBM 704 -> i704 IBM 704/709/7090/7094 -> i7090 The i7090 can be set to simulate a IBM 704 however you end up disabling almost everything, since the 704 did not have any channels. A build option exists that allows this one to be built without all the extra features. The i7090 simulator’s implementation of the IBM 7094 is a more complete implementation of the IBM 7094 which can run CTSS while the existing simh I7094 can’t.
