To all with interest in IBM 7090

Please note that I said nothing about a computer museum using simulators. The question asked was: I replied: Note no museum use was mentioned. Simulators work well for this, and can be run from the comfort of anyone's home. No museum required. So please reconsider your post and how things were actually said. Please do not stoop to Tony's level, twisting my words at any occasion - you will end up soiling your reputation (back to the "don't be a dick" idea). Anyway, here is a fun thought experiment. Consider two absolutely identical big machines from the 1960s. Take one, and restore it to operation. Take the other, and put it into a museum archive and preserved. Wait 30 years. Now, in 2042, compare the two machines. The running one will be quite a bit more "used" than the preserved one, just from normal wear and tear on the components. Now here is the twist - in 30 years ago, simulators will be magnitudes beyond what we have today. Simulating not only the architecture, but the sounds, smells, colors, textures, and so forth. Yes, virtual reality. Now, what would you want your near perfect simulation to be based off of - the machine that was used far longer than its normal working history, or the one that was preserved as it was just taken out of service? -- Will
