Edit for whoops, that's Atarisoft! For some reason I processed the word as "Applesoft" even though I've had minimal contact with those programs...
Today I got a rather large, light box from Sun Remarketing - they had packages of the Atari Applesoft games for sale on eBay (at a good price - I think it came to about $.50-$1 per game, before shipping). Very good stuff - the boxes look brand new, with the occasional corner ding, shrinkwrap seperating on the side and one box had gotten a bit folded, but overall very, very nice (I think all the big ones have their hangar tabs)! I won't be breaking these out of their boxes anytime soon, but I should be able to find images of all the disks and simply emulate.
So: They run on Apple II computers including the IIe (no idea if they're enhanced, most likely not) and require 48K of RAM. The boxes are mostly orange, the layouts are standard. The backs don't have actual screenshots, but do have nice looking pixelated, outlined approximations of gameplay; you wouldn't be embarrassed to have these on a shelf somewhere. The copyright dates I saw were 1984; so...no Gauntlet :(
There are two main styles of box: one's about the size of an old PC game box; the other is roughly the size of the new small-size game boxes in stores now.
In small boxes (6):
Battlezone
Galaxian
Gremlins
Jungle Hunt
Moon Patrol
Ms. Pac-Man
And in an extra wide small box, as it comes with its own hefty controller:
Track and Field
Big boxes (7):
Centipede
Defender
Dig Dug
Donkey Kong
Pac-Man
Robotron: 2084
Stargate
There were some others listed on the backs of some boxes, here's what I got off one (5):
Crystal Castles
Donkey Kong, Junior [as listed]
Joust
Mario Brothers
Pole Position
So - 19 titles in all should exist.
