Both bands are 960 × 80 dots — the page-size table in PM.TOS at 0x13a64, indexed by page type. Stationery takes no border and its artwork always sits at y = 0, repeated by a count table at 0x14160: Left side once at x = 0, Right side only flush right at 960 − width, Both sides both, Row of six six copies every 160 dots, Tiled ten every 96. Lines advance by height × size + 4, and the nine fonts carry their real cell heights and advance widths from FONTS1.FSZ — including Editor at 8 dots, which the hotel letterhead on the disk uses for its address lines. Dots are 120 dpi across and 72 down, so the proof is stretched 5∶3 vertically to stand for ink on paper.
