A light xterm. And it's actually lighter! Not tabbed.
I got this working with a nice vga font from DOSEmu. See 9x15 versus DOSEMU's vga font. However, I learned that aterm does not support unicode. It suggested rxvt-unicode, and I got it working with a nice unicode vga font. See Unicode VGA font for that info.
