Описание к видео HD38800

This is a combination of a 4-bit microprocessor with a VFD driver from brand HITACHI.
It requires some care related to the power pins, as it uses the VSS mnemonics as positive (+10V) and VDD as negative or 0V.
The video was a little long, but I can't focus on all the topics in a short time. I believe it's worth it because this practice can be applied to other identical panels!
