[Techtoolslist] RASTER: M2716A-2F1 datasheet

[Matthew Rossiter]

So, in continuing this discussion on techtoolslist - I found that I was 
only about to program a couple more 2716a's and the rest failed.  Then I 
realized that sometimes I had to program them two or three times until 
they finally verified correctly.  Has anyone else run into this issue?
