I noticed that it was an engineering sample, but hadn't really thought
about that making it more valuable to collectors. Perhaps I should
sell that chip and buy a production 4040 for my homebrew system.

I'd also like to get a 4201 clock generator, 4289 memory interface
(replaces 4008/4009 pair with one chip), 4265 GPIO, and 4269
keyboard/display interface.  And some 4002 RAMs.
