I used those to get enough ram to run Red Baeon II on my 286 Packard-Bell...With a whopping 40 MB HDD. I could get a few games, some Warez and some utilities on there. A buddy reformatted my drive with some sort of reserve partition which kept file sizes smaller than 1k using 1k of disx space. It added a few more mb of storage space.
The reason I mentioned those was that there were certain games back in the old days that needed lots of tweaking of things to work.
