Over the weekend we had a chance to visit the Computer History Museum:
It is a must see! Especially while they have the Charles Babbage's Difference engine.
You can see me here marveling at it :-) :
You can also see Melody obviously enjoying the role of the "Mad Scientist" :-) :
Here she is only reaching to the knobs, obeying the "Do not touch" sign ;-) .
I greatly recommend you visiting the place. There is so much we have forgotten or simply never knew about the early days of computing!
