When someone wants to "stress test" memory, The first thing that pops into my mind is to find out if the memory is good or bad. The best way is to find a program that runs under DOS off of a floppy disk. Sandra runs under Windows. If you look for AMIDIAG, this program runs off of a floppy disk and runs under Caladra DOS, or was it IBM DOS, I forget. But you get the point.
