There were approximately 15 Model 91s produced. The Computer History Museum has the console from one, and the Living Computers Museum has another. The Model 95 was the even more rare version with thin-film memory instead of core memory. Only two of them were produced, for NASA. The Model 195 was a reimplementation of the Model 91 with "monolithic" integrated circuits instead of hybrid SLT modules. The System 370/195 was very similar to the System 360/195. Curiously, the System 360/195 has the black styling of System/370 control panels, rather than the beige control panel of System/360. https://en.wikipedia.org/wiki/IBM_System/360_Model_91#Models_built https://en.wikipedia.org/wiki/IBM_System/360_Model_91#Models...
