Remember the old Austin/Morris 1100/1300 mechanical "bargraph" speedo...?

Sorry, long before my time ;-))

I'm sure there must be whole ergonomics textbooks on this stuff...

We had a situation today, measuring an incredibly accurate part we have made (mechanical part) using an electronic gauge with an analogue meter on it. We realised that a digital readout would have fooled us completely about the exact shape of the part we had made. So I agree entirely. Sometimes, nothing beats an analogue indicator.

The World is an analogue stage, the computers only have Bit Parts.....
