Hi, All

I updated the progress of this project.

Now we can see the running status of this calculator.

Although there is a lot work to be done to improve.

Very nice project! Very similar to my version, the prototype is still working, but I never managed to get it reliable, the ftdi chip kept dieing, I think it is the supply for the tubes that causes this, but I never got quite to the bottom of the problem. There is too much other stuff going on in my life so I kind of dropped the project.
Hope you have better luck with it! Looks very good so far!
