I started with the 16C84.  Bought a couple, built a programmer (Tait)=20
and downloaded the Parallax assembler.  After getting comfortable with=20
them, I went to buy more and found they were obsolete / not available=20
(at least, not from Digikey).  I couldn't believe it, so many internet=20
projects used them.  Turns out, the 16F84 is a drop-in replacement.  No=20
circuit changes, programs the same, etc.  So there really is no need to=20
continue making the 16C84.
