If this were my project, I would read the VT100 manual and design and implement a serial driver and basic text window library from scratch running on the bare hardware. It wouldn't be more than 1000 lines of C, more likely something like 500 lines. I am a retired embedded software engineer and did these things for a living. I would budget 2 to 3 days including reading the manual.
