Really late serial terminal designs are essentially that, x86 cpu and chipset
running a dedicated program from rom.
Spare Time Gizmos built a pcb that was a VT100.

If you REALLY want VT100 accuracy, put MAME on a RTOS emulating the VT100
I had given some thought over the last day or two about making a really tiny
video terminal.
A while ago, I had bought a couple of tablet ARM SOC LCD notebooks to try doing
that.
