Suspension Chamber 2000

The SPC2000 is a sleep chamber manufactured by Nya Elektriska. The last surviving humans slept for 16¹², or 0x10^c in hexadecimal years in SPC2000s, due to an endianness mismatch.

Interrupts

When a HWI is received by the SPC2000, it reads the A register and does one of the following actions:

A	Behavior
0	GET_STATUS Sets the C register to 1 if the SPC2000 is ready to trigger. If it's not, the B register is set to one of the following values: 0x0000: ######################## - EVACUATE VESSEL IMMEDIATELY 0x0001: Not in a vacuum 0x0002: Not enough fuel 0x0003: Gravitational forces too uneven 0x0004: Too much angular momentum 0x0005: One or more cell doors are open 0x0006: Mechanical error 0xffff: Unknown error - EVACUATE VESSEL IMMEDIATELY
1	SET_UNIT_TO_SKIP Reads the B register, and reads a 64 bit number from memory address B in big endian, and sets the number of units to skip to that number.
2	TRIGGER_DEVICE Performs GET_STATUS, and if C is 1, triggers the SCP2000. The status can be read as the result of the GET_STATUS call.
3	SET_SKIP_UNIT Reads the B register, and sets the size of the unit to skip to one of: 0x0000: Milliseconds 0x0001: Minutes 0x0002: Days 0x0003: Years
