Take a look at Jim Thompson's early design. He's an IC designer who
hangs out on the sci.electronics.* newsgroups.

Yes, I've seen Jim's design before; it's quite impressive for 1974! For a
contemporary design, the idea is that you could get by with far fewer parts
(if not fewer transistors -- they're just buried in the ICs!).
