WeibullSMITH is a DOS based probability plotting software which has been upgraded to a Windows based program known as WinSMITH™ Weibull .
WinSMITH Weibull is a far more versatile Windows program from Fulton Findings for analyzing reliability data than WeibullSMITH. We recommend you discontinue use of your DOS version of WeibullSMITH and upgrade to WinSMITH Weibull. WeibullSMITH has reached the end of its evolutionary tree.
If you're stuck in a DOS environment, Barringer & Associates, Inc. can procure WeibullSMITH for you on a special order basis ($380/copy plus shipping and handling for DOS version 6.8). We no longer stock this DOS program in our inventory, as WinSMITH Weibull is superior to WeibullSMITH.
