Eric that's an excellent work and very inspiring. I wonder how much time you spent on it!
I have a desk calculator with VFD to repurpose as a clock. I will keep your result in mind when I will be reverse engineering the circuit, in case I can hook it up in a similar way you did. Not knowing how such a calculator works I originally meant to emulate keypresses and increase the displayed time as a simple addition. But now! My calculator keypad is a matrix of some sort. The uC is a generic 4-bit microcontroller Hitachi HD614080 that drives directly the 12-digit VFD. Reverse engineering ahead. Let's see what I will come up with. And how long it will take. Meanwhile I will look at your video few more times.
