Swordfish~..................your problem was 8Mb of RAM...............that is really a Win3x/DOS configuration.............Win95 will work............but expect serious instability................NT4.0 really needs 32Mb absolute minimum, and 64Mb+ out of choice..............processor wise it is not that aggressive...................I have run it quite happily on PI/90-PI/166 machines.
I know i needed more RAM But as i said it was my first System..and at that time Hardware... Especially RAM was very very Costly...and i somehow Loved NT as a OS ....ok ok to tell the truth it wasen't by choice i had to run several Back Office Products that only run on NT(server) at that time....i was very very slow .......i didn't had much of a choice

and about "Windows NT processor wise not being that aggressive" very True it worked resanobly good on 64 MB RAM.....

Now RAM and other Hardware are very cheap as compared to those days....and i am very glad about that...

--Good Luck--
