24 bytes by 112 lines, running on through LOADER_LEFTOVER and BUFFER_REST to the attribute buffer (ATTR_BUFFER). The town and the objects are drawn into it each turn (PUT_TILE, DRAW_SPRITE), and at the end of the turn it is copied to the screen (COPY_BUFFER) and cleared (SHOW_PLAY_AREA). Row 0 is the play area's bottom line, y 72, since the game's y counts upwards; only bytes 2 to 23 of each row are shown, in columns 7 to 28 of the screen, the first two being a margin that sprites at the left edge are drawn into unseen.

These first 60 bytes are the end of the game block as the loader moved it (LOADER): zeros, loaded with the game but never anything but the buffer's.
