/* The Real Time Clock and Timer (wrist watch type)
 * This device hangs off the I/O board cops and is communicated with
 * through the console VIA (ie. l2copscmd).  The command byte is as follows:
 *	0x02	read clock data; the setting of the clock is returned as
 *		a seven byte reset code.
 *	0x2C	start clock and alarm set cycle.  Upto 16 nibbles of alarm
 *		and clock data (aaaaa y ddd hh mm ss t) may be sent as the
 *		low nibble of the following clock command.
 *	0x1n	write nibble `n' to clock (only valid after 0x2C cmd)
 *	0x25	terminates setup cycle and enables clock, timer is still
 *		diabled.
 * The Clock is connected to the power circuitry and can turn the system off
 * or be programed to turn it when the timer underflows.
 *	0x20	disbles the clock, timer, and shuts the system off.
 *	0x23	shuts off system leaving clock enabled and timer set to
 *		power up on underflow.
