IBM released OS/2 2.1 Korean version in 1994. I had a desktop computer at the time. The spec was 486sx, 120MB HDD, and 4MB memory. OS/2 2.1 was pretty slow, however, Os/2 can do multitasking jobs. I bought a Toshiba Laptop as a secondhand and added more memory and installed IBM OS/2 2.1 on my Laptop.
