I had that. I remember distinctly a number of pages. One was the adventuring group gathered 'round a table in a tavern (some part of my brain tells me they were
al fresco) just before they set out for the dungeon. Another was the attack by the Umber Hulk which IIRC killed one of the party members. Then there was the encounter with Tiamat, which went something like this: the party opens a door in the dungeon, they see Tiamat sitting on her hoard, they slam the door and keep moving. Gotta love those Gygaxian dungeons

Man - bringin' back the memories.
