I want to output my Z80 computer to a VGA screen. I know that I could attach a UART and RS232 level converter to the Z80 then output through a serial interface via a PC, but is there any way that I could create a circuit to use this serial data to then output to a VGA monitor? I have seen many tutorials on the internet on how to make a VGA controller, but all of these focus on just putting an image on the screen. I just want to use the VGA monitor as a serial text terminal, no images.

People have done this with PICs. Search for "PIC VGA output".

I am surprised that there is not a custom IC to just take serial data and dump it to a screen in the way that you would a PC via a terminal emulator, but instead to a VGA monitor. It seems like it would be a useful debugging tool.
