I cant understand why such a crap design are still made?
Even a simple neatly done discreete design would out perform
the 8038!

There should be a list of "worst-IC-designs-of-all-time" it would 
also be nice with a list of the most "neat" IC design of all time to!
In the first list i would definitively put the 8038 and a bunch of
early FM chips! In the second list i would put the 555, the 4046.
