1.0A - First Windows-based version of both WinSMITH(TM) Weibull and WinSMITH Visual software bundled into the SuperSMITH(TM) package.
NOTE: Our WeibullSMITH(TM) software for personal computers pioneered the way as the first widely-used Weibull engineering program starting in the middle 1980’s. Then our SuperSMITH package, with WinSMITH(TM) Weibull + WinSMITH Visual + WinSMITH Ybath, took over as the most popular Weibull Engineering program available.
