The DMV driver seems to have lost the ability to draw the graphics in AutoCAD between 0.235 and 0.236 (there was a µPD7220 change for that release).

I have a HD image set up to replicate the issue. The DMV.BAT file in the archive gives a nicely maxed out configuration for the machine after you adapt the file paths to match your MAME setup.

Boot into DOS, enter "CD ACAD", "ACAD", type option "2" and the drawing's name, e.g. "NOZZLE" or "COLUMBIA".
