It's a high voltage VFD display, you'd need something like an old Nixie tube driver to get it lit.
Stick with your 8085 studies, make an effort to focus on one subject at a time. In no time you'll be computing like it's 1977.
Want a nice easy to learn MCU, try the ancient CD1802 from RCA. Only had 30 or so instructions but it was SOS and good enough to be put into space probes.
Nixie tube need near by 220V, but this VF were used in small calculator that mean it circuit give high voltage if you tell me about how to give it supply rest of work i can do my self.

It wasn't a micro-controller, it was a VERY old micro-processor - it was used on space probes because it was low power CMOS, could easily be programmed remotely, and was fairly impervious to radiation of various types. However, I don't recall it only having 30 instructions?.
