On page 356 of Cary Lu's "The Apple MAcintosh Book", the description of the
clock/calendar says:

	The very low-power CMOS clock/calendar operates off the battery and
	contains its own small separate memory in a custom chip. Besides
	date and time, the memory has a few extra bytes; these could be used
	to store a computer configuration -- possibly identifying the user
	as a novice or expert. An application programmer could query this
	information and take different strategies depending on the answer.

[1] Is this true?
[2] If so, how many bytes?
[3] What is stored there? (Is it the same memory as the 20 bytes described
    by mnodine@BBNH.ARPA in his/her message of approximately 21-jul-1984,
    subject "RE: Rebooting options; what's kept around?")?

	Karl.
