Huhn, I didn't realize Holmes was initially '77. I got mine in '79, with B2 Keep on the Borderlands, for Chistmas. Still had the chits, instead of dice. I was only 10 and the rules were beyond me - my dad had to read and explain them to me. Sadly, I lost the rulebook after a month or so. Didn't have another rulebook until the '81 Moldvay set, which I loved to death.
Some of the earlier sets had dice, then chits, then the dice returned.
That 1977 box set included dungeon geomorphs and the monster and treasure and assortment. In 1978 they replaced those with B1 In Search of the Unknown, and then replaced that in 1979 with B2.
Which was also included in the very excellent Moldvay box set, which of course was the first D&D product I had.
