Greetings,
This appeared on another thread in this news group. A couple of people wrote and said others may not have read that thread and would still be interested so I'm reposting it here.
If you want to see a very interesting photo of the internals of the Mostek MK-5017 clock chip used in a Heathkit digital clock from 1972, then visit my web site at:

There's a little surprise on the chip.
There's also a link to another web site with quite a gallery of other chip photos for those who aren't aware of the Silcon Zoo.
