The kcs is excellend voor basic pc work. Games work perfectly, but ega and vga are slow. Tandy and cga are abit faster. You also need some fast mem, to see al colors (vga +soundblaster mode). I worked with it for years (before i blew my old A500 -rev8a).
MS-dos 6.22 was no problem and windows 3.0 worked great.
