It should support a CRT by doing this:
1. Buy a hdmi to vga converter, you can buy them on amazon or ebay for less than $10.00.
2. Use an OS like Linux that uses a config.txt file to store bios like settings. This is handy for embedded systems like the pi and allows you to to use something like 640x240.
By pi is connected to a CRT using this method through a j-pac.
