Dear Friends....

I know (a lot !!) on how to do uniformity .. i have doing three or more times at once with no error.  Keep in mind you must be organized and very concentraded (?!) or not distracted by anything !!!  

What i do is have a bunch of diskettes and record on two of them an latest unifomity from 2611 and another disk the same but ON THIS DISKETTE YOU ARE GOING TO SAVE THE NEW RESULRS FROM THE COMPUTER.

I like also to grab (print screen) of the results coming from UNIFORMITY SOFTWARE... why ?  Just for to be sure that the results are getting better !!!

Say that you get a good result but you want more .. but and if the next uniformity you don
