The author discusses their experience running OS/2 6.123 on their PS/2 model 80. They explain that running MS-DOS based games on this system often leads to instability and crashes, causing frustration. They mention one game in particular, BattleTech, that they had trouble launching on their model 80 board. The author suspects that the system’s lack of a math coprocessor may be causing these issues. They acquire a math coprocessor and install it, which successfully improves the system’s stability and allows BattleTech to run smoothly. The author reflects on the potential impact of early 386 processors’ defects on the development of OS/2. They also mention their experience with AIX on a previous PS/2 model 80 and discuss the importance of having a math coprocessor for older systems.
