HP-29C - Brighter LEDs?

[Tom Flatterhand]

I could imagine that HP-25C and HP-29C actually differ less. After all, they are presumably both newer models in the context of the then newly introduced 'Continuous Memory'. I was referring to the second programmable pocket calculator from HP, the HP-25, without Continuous Memory.

I can see the difference very clearly. I attach a few comparison pictures. If you can't see it well there, I can also show you a picture with manual exposure setting, but I'll have to make it first. These two here were taken with a smartphone, where I can't dial down the exposure as much as I want, so it may not be as clear.

The reason I ask is because I want to make sure the HP-25 doesn't have a bug.
