 For some reason, CGA AutoCad never really caught on.   
I'm sure there's very little if any CAD for CGA. The oldest program I 
personally used was OrCAD, and that was in the 5170 PC-AT days, and 
that was, IIRC, EGA, or at least that's what was on the machine I was 
using it on.

The first half dozen or so versions of AutoCAD could run at CGA resolution. I ran my first
version of AutoCAD (2.08, Release 5) on an XT clone with a CGA card. Later, I was able to
afford a Techmar Graphics Master. I could run that at 708 by 708 monochrome on the same XT
clone. I still have the software, but unfortunately no longer have the Techmar card. I
have also run AutoCAD 2.14 (Release 6) on an HP 200LX palmtop, which is basically CGA. It
can be done, but the limited resolution does hamper what you can do. 

I also have a copy of AutoCAD 1.4 (Release 4, 1983) that was customized by John Walker to
run on an Otrona Attache 8:16 for an archaeologist colleague at the University of Chicago.
The Otrona has a strange software emulation of CGA!
