Atari 2600, 1 heavy 6 switch, 1 or 2 4 switch, 2 jr models.
4 large boxes of games, something like 300 of them. I've already found a few rare ones like Texas Chainsaw Massacre
Atari 5200 and 20-30 games
Atari 7800 and maybe a dozen games
Sega Master system and a couple dozen games, with 3d goggles (housing cracked but functional)
NES with a couple games
SNES with a few games
N64 with quite a few games. I got paper mario, golden eye, and a few other good ones.
*Vectrex* with multicart
This is quite possibly the coolest thing I have ever owned.
A pong system.
A Fairchild Channel F system with maybe half a dozen boxed games.
This was apparently the first video game system with interchangable cartridges
a box with a bunch of assorted Atari 8 bit, coleco, oddyssey 2, intellivision, and probably cartridges for a few other random systems
another box full of game manuals and marketing material
I already went through this box and found a bunch of intellevision overlays (!) and original Sonic 2 and Toejam & Earl posters that were packed in with games. They're getting framed!
Oh yeah, and a huge box of controllers with it! I've got all sorts of weirdo controllers. Like the Amiga Joypad, remote control 2600 controllers, and a whole lot more.
I've taken a few pictures so far, here's the whole collection in the condition I got it:

Here's the pong and the vectrex:


The total cost for all that was $425. I think it's got to be worth 2-3x that much, especially with all those weirdo controllers. I'll take some pictures of them, I'm going to need some help identifying some of this stuff.
