If you just want to have the progman interface, you could install NT 3.51. With the lastest patches at least the latest version of Firefox2 will work. I havn`t tried FF3. With addional work Flash 7 (can`t remember exactly) can be used. NT 3.51 will have much more RAM instead of 3.11. Officially it needs 12 mb, but I`ve heard that 8 are enough to run.
