I'm using QuickBasic (DOS version) timing via interrupts - works well.
Tried timing how many FOR/NEXT loops (incrementing a counter) executed in,
say, one second and this would give a fairly accurate means of CPU speed
estimation.  Adjust your loops accordingly from the number contained in the
counter and various machines seemed to time ok.  Tried this on 486x33Mhz up
to 686x333Mhz - worked on both.  Don't know a da**ed thing about VB,
though, so how DataMaster does it, I haven't a clue.
