While some people use Classical Dungeons & Dragons to refer to both the original D&D booklets from the mid-1970s and the various Basic, Expert, etc. Dungeons & Dragons boxed sets sold in the 1980s as a separate line from the Advanced Dungeons & Dragons game, this site uses the term to refer only to the 1980s boxed sets (and the Rules Cyclopedia published in the early 1990s) and the adventures and accessories designed for them.
While some players of Advanced Dungeons & Dragons looked down their noses at this "plain" Dungeons & Dragons because the "advanced" part of the name held snob appeal for them, Classical D&D was every bit as good a system as the first edition of AD&D (and arguably better than the second edition). It just made different design choices and was designed to be learned in stages with new rules added as characters advanced. According to reports from TSR employees, it sold almost as well as first edition AD&D.
There were two major editions of Classical D&D. The first consisted of two boxed sets: a Basic Set by Tom Moldvay and an Expert set by David Cook. This version is often refered to as B/X or Moldvay/Cook. The second edition was written by Frank Mentzer and consisted of five boxed sets: Basic, Expert, Companion, Masters, and Immortal. This version is often refered to as the BECMI edition or the Mentzer edition. The Rules Cyclopedia, edited by Aaron Allston, combined the rules material from the first four Mentzer boxed sets with some new material (and some new errata).
You can discuss Classical D&D on our message board in the Retro Fantasy: Gygaxian D&D board.
TSR kept the classical version of D&D in print -- in one edition or another -- from 1981 to the mid-1990s. While they are now out of print, copies are easy to get (and often very affordable) on eBay -- click here for more information on buying Classical D&D items on eBay. Copies in PDF format are also available for US$5 or US$6 a book or set -- except for the 1981 Basic/Expert sets, unfortunately.
Fan "restatements" of older editions of D&D using the Open Gaming License and D&D SRD from Wizards of the Coast have become fairly popular in recent years. Two versions of the classical D&D rules are currently available in a "restatement/simulacrum" edition: Basic Fantasy Roleplaying and Labyrinth Lord. Both seem to be based on the B/X version of the rules. While they both have minor variations from the original TSR rules, both are so close that it is a no-brainer to run published classical D&D adventures with them. Both are available as PDF files for free or as low-cost print-on-demand version.
The classical version of D&D has a number of rulebooks -- in several editions -- which can make getting started a bit confusing.
That said, I personally recommend either using the free Labyrinth Lord rules or just picking up the Rules Cyclopedia. Either is an inexpensive solution that is easy to use with all of the published modules. This lets you spend more money on adventures and campaign settings. (I'd pick up a pdf of B1 or B2 to start with and a pdf of GAZ1 to use as a setting.) Total Cost is under $30 and that includes a used copy of the Rules Cyclopedia hardback.

Title: D&D Immortals Rules Set 5

Format: box, 52 page rules book, 32 page book
Comments: This boxed set was designed to take Classical D&D a 36th level character who has completed a special series of tasks and quests and allow me to become an Immortal. Immortals were the deity-like figures in Classical D&D. As an Immortal, the character could be played through another 36 levels in a special Immortals campaign. This was an interesting idea. Unfortunately the rules were probably only understood by the designer, Frank Mentzer. After the Rules Cyclopedia was published, a revised and much more understandable set of rules for Immortals was published in The Warth of the Immortals boxed set. This was the final box in a set of 5 boxed sets designed by Frank Mentzer to take characters from 1st to 36th level and possibly beyond into the realm of the immortals with 36 additional levels.

A large number of adventures and supplements were published for Classical D&D over the years. Most are usable with any version of Classical D&D without major modification and can easily be used with Original D&D or First Edition AD&D with only a little effort from the gamemaster. The major exception to this is the Immortals modules which really only work well with the Immortals Set of the BECMI version of Classical D&D.
For the most part, TSR adventures for Classical D&D were divided into series based on rules set. B-series modules only needed basic Set rules, X-series modules required the Expert Set, C-series modules were for use with the Companion Set, M-series modules were for use with the Masters Set, and the above-mentioned IM-series modules were for use with BECMI Immortals Set.
These adventures were designed for use with the Basic Set -- character levels 1 to 3.

Title: In Search of the Unknown
Author: Mike Carr
Published: 1979
Format: 32 page book
Description: This package (a cover folder with maps and descriptive booklet within) forms a complete module for use with DUNGEONS & DRAGONS Basic Set. It is especially designed as an instructional aid for beginning Dungeon Masters and players, specifically created to enable new Dungeon Masters to initiate play with a minimum of preparation.
In addition to descriptive and situational material, this module also includes special informational sections giving: background history and legends, listings of possible monsters and treasures and how to place them, a list of adventuring characters, tips on various aspects of play for the Dungeon Master, and helpful advice for starting players.
Comments: This adventure was designed as a teaching tool for both players and dungeonmasters. Many rooms in the dungeon were intentionally left empty for the DM to fill in. There also was a lot of how to run an adventure advice as included. This adventure is a good first adventure (and a great tool for learning to be a dungeonmaster, but B2 was probably a better "first adventure" experience.
