This is where the game begins, and where it comes back to after 'you are dead' (see 903C). It is the reverse of 6C00: the backed-up copies of the object table, room table, variables and timer tables are copied back over the live ones, so every object, character, door and timer returns to its starting state.

It then sets the border to black, waits for a key press (the IN A,($FE) loop at 6C6E: keys read as 0 bits, so the loop continues while all five bits are 1), sets up the text window variables used by the printer (75AD), clears a 200-byte work area at B628, and seeds the random number generator from the Z80's R (refresh) register at 6C9E. Because R counts instructions, the seed depends on exactly how long the player took to press a key, which is why every game plays out differently.

The routine then clears the screen (6FCA), draws the bar that separates the story window from the input window (a 5-line pattern from 6DC3, repeated across the screen at $5140), sets the line counter used by the story window's pause (7694) to 17, and, if this is a fresh start (the frame count at $B5F7 is $FF, as it always is after the variables are restored), makes the game's random choices (970B), puts the first command, LOOK, into the input buffer (copied from 6FEB to 6FF0), and drops into the main loop at 6D0A.
