Ran the LM741 through sams software also.  It crosses to the 941M.  
Which..is confusing because the TA7504M crossed to the 941 which is a 
metal can package.  Hehe.  It's been a long time since I tried to cross 
a 741 since I always have plenty of them.   But probably they're near 
the same thing then.  -Bob
