"John Lewczyk" <jlewczyk(a)his.com> asks about the 8530:
A search of the web yielded lots of links, but no
datasheet. I want to know
how to program it and its electrical characteristics. You know, the stuff
on a datasheet. Zilog's web site doesn't have it.
[ Its the chip used in the Apple Lisa and Mac and LOTS of other devices. ]

Near the bottom of the page is a technical manual covering the 8530H
and 85C30, and a data sheet and errata sheet on the 85C30. Note that
the 85C30 has some additional features that were not available in the
NMOS/HMOS part; these should be called out in the docs.
