For those who might be interested and haven't yet heard, over at DriveThruRPG/RPGNow the
original Dungeons & Dragons (0e) Boxed Set (White Box version) is available in PDF format. Again. Now they just need to come out with the supplements.
Blurb from the product page.
"First published in January 1974, the original edition rules of Dungeons & Dragons would go on to see six different printings. This edition is for the Original Collector's Edition released By Wizards of the Coast in 2013, which was itself a revision of the 6th and final printing, the "Original Collector’s Edition" or white box edition.
You get all three books contained in the original boxed set: Men & Magic, Monsters & Treasure, and Underworld & Wilderness Adventures plus the Reference Sheets booklet.
Great to read and still great to play, the original edition shows you where the roleplaying hobby began and the original version of the game that spawned a hobby."
The covers are the re-release covers not the original artwork pictured. If you had previously purchased the PDFs, prior to their removal years back, you can download the new version gratis. Get them right
over here.
If you're hankering for a classic science-fiction game instead, then Jim Ward's original TSR 1st Edition of
Metamorphosis Alpha should fit the bill quite nicely.
Edit
On the heels of the
Original Dungeons & Dragons Boxed set releasing in PDF we now have
Supplement I: Greyhawk in PDF form for $4.99. It's only a matter of time before the rest get released, I suppose.
Edit #2
So they're coming out in dribs and drabs. The
Blackmoor supplement was just released.
Edit #3
Eldritch Wizardry, OD&D Supplement III, was released on PDF today - 40 years after the original in 1976. Just one more supplement left.
Edit#4
The
Gods, Demi-gods & Heroes PDF is now available at
dmsguild.com (formerly
dndclassics.com).
NB the Hyborian and Melnibonean mythos found in the original booklet have been removed.
