Is it possible to do something like this by using the server’s PS/2 keyboard port and VGA monitor port?  So, essentially a KVM without the “M”?  Is there some obvious constraint that I’ve missed?

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.
