So, let's begin at the beginning with some much-deserved Atari love, courtesy of the Atari Museum. You can grab 11 issues of Atari Age here, 6 issues of the Atari Club Magazine here and (re-)discover what the Atari 2600 and to some extent 5200 were all about. You will also find the Atari Connection Magazine, the Coin Connection newsletters and St. Pong's Gospel.
The Out of Print archive is another stunning place indeed. It's filled with high quality scans of some of the very best old game magazines, among which you'll find: N64 Magazine, Raze, PC Player, Super Play, Dreamcast Magazine, Sega Pro and DC-UK.
Compute!, a rather more serious take on the then-emerging digital scene, was first published in 1979 and featured content mostly on the Commodore PET and the 6502 processor. The complete magazine archive from 1979 to 1994 is available here. Yes, all 168 issues of it!
ZZap 64!, the everlasting pride of the Commodore 64 community and one of the best gaming mags ever, is available in its (almost) full glory here. Though you wont get every article of every issue, there’s more than enough scanned and html-ed (?) content to keep every misty-eyed 8-bit connoisseur off the streets. Besides, content is being added regularly.
Just as C64 replaced the PET, an time came when the 16-bit powerhouse that was the Amiga replaced the C64. Tons of magazines were published, gamers were having multiple orgasms and the utterly amazing Amiga Magazine Rack is the place were everything is kept safely for your free retro pleasure. 70 classic mags are covered, including The One, Zero, Amiga Action, Amiga Computing and Amiga Joker!
You can also found The One issues over at the Internet Archive.

Atari ST gamers and users can, on the other hand, pay a visit to the ST Magazine Archive. It already sports issues of Ace and The One and is regularly getting updates and new scans.
The Lucasarts Adventurer wasn't exactly a gaming mag, but it definitely felt like one and can still be downloaded for free over at the aptly named Lucasarts Adventurer blog.
People that preferred Sierra On Line's offerings will of course be thrilled to find out that Sierra InterAction is also available in all its PDF glory.
