How to replicate old crt screen look?

I want to replicate the look of the old crt terminal.
My thought was have 2 layers of text, bottom with blur then merge them. Then add noise layer on top.

I would have to make custom bitmap alphabet for the glowing letters but they would have a larger footprint then normal and the spacing would look weird.

Any other ideas?

If you look closer, on the old computers they used fonts with fixed character width (monospaced).
So you can make a set of images all the same size for all needed characters (including glow and noise) with as thin transparent borders around the glyphs as 1 pixel (or even 0 if you wont mind the glyphs touching each other without gap). Problem is how to impose glow on the empty neighbor areas, that spreads further than thin gap between characters.
