Python • Is Python on a Pi4 fast enough to generate a monochrome video signal?

I'm looking for a way to test old CRT monitors. These typically use monochrome display adapters (MDA) or similar.
4 TTL signal wires:
- Vsync
- Hsync
- Data
- Intensity (I think?)

I came across lots of documentation on how the Pi can generate various bit-depths of RGB signals on its GPIO pins.

But I need something simpler. And I have not found any info on doing that on a Pi.

I have a Pi4 handy, am thinking of giving it a go. But before I re-invent the wheel, though I had better ask here first!

Thanks in advance,
Richard.
