If you have a "stock" IBM PC, just the standard dual 360K floppy drives without a hard drive, it's actually possible to run this demo!

Use DOS 3.30 and FORMAT /S a blank floppy, copy APPEND.EXE to the floppy, and copy as many of the AREA5150 demo files as will fit. Then copy the remaining files to a second floppy. Put first floppy in A: and boot off it, put second floppy in B:, and then run APPEND B: followed by AREA5150. Behold, it works!

You absolutely do need the full 640K of RAM though, refuses to run with only 512K.
