Right, ok. But don’t forget the other side: a modern machine with tighter tolerances, faster processors, etc. will be simpler and perform better, with better speed control, less wow/flutter, etc. It’s similar to how a modern car engine will require no tune ups and hold idle better than a restored ~1950s car. That processor can be replaced, the eProm can be reprogrammed. Ultimately, you are turning a tape past a head, it’s not rocket science.
If everyone had the same perspective, the R2R industry would not grow and would likely die.
