Sharp PC1211, briefly an Casio FX-601P and then HP-41C.
After that been HP all the way )))

Mind you just been using an FX-602P recently (RAM upgraded FX-601P) and it is a pretty decent calculator, despite the fact that when I recall M 22 (I think) it comes out incorrect )))) The Calculators RAM is beginning to fail (1980 Calculator though) an apparent common fault with this model. Have not heard of 41C's with this issue (think launched somewhat less than a year apart, Mid 79 the 41C and Mid 80 the FX601/2P).
