1 file, 163 blocks + 23 block instruction file.

While the crackintro says "cracked on 8-12-86", the instructions say "written on the crackday 18/12/86" and goes on to mention their release of Gauntlet on the same day. As far as we can see, the first ever release of that game was made on the 12th, which leads us to believe the 18th is the correct date.
