Hi Geert,

This document appears to be Inside Macintosh vol. III ch. 2. It describes the early RTC chip that lacks two-byte operations and XPRAM, and pre-dates all Mac hardware supported in mainline Linux. But it does offer some useful data, though not enough to answer all of your criticisms (as I said).

So, unless you have other ideas, I will revise this patch and insert an earlier patch to address existing code, and codify what little reliable chip data we have.
