I have done some more work on the new Game Boy style screen.
I think it is about as good as we can get without actually having the DMG shader.
I have also done some more work on the Apple II.
After looking at some more reference images I removed the texture from the bottom half of the floppy drive face.
Then, for the background, I created date appropriate software manuals and swapped out the 3.5" floppy disk box for 5.25".
Finally, I tweaked the CRT settings to be more in line with the monitor technology. (Removed the mask, adjusted glow and scanline properties.)
