<os/2 version 1.3 requires at least 2 meg when configured for dos and native
<apps. i'd suggest 2.0 or higher since it has the workplace shell. if you
<can't get os/2 running well on a pentium, you're not doing something right.
Well in my case it's a 286/10 with 1mb ram if it needs more I'm cooked.
But there is Minix, DR-dos, CCPM to try.
