What the heck do I have?! Is this a prototype??

[Satoshi_Matrix]

This might not be the best place to ask, but I've already posted this on AtariAge and thought I might get more insight by asking here as well.

About a month ago, on a residential side street in Toronto, I came across...an unusual find. Standing on the ground near the sidewalk was an old plastic case holding 14 Atari 800 games, and also an Atari 2600 Joystick.

I don't own an Atari 800 to test any of these but here's what I got:

Pole Position RX8034
Star Raider CXL4ON
Pac-Man CXL4022
Donkey Kong RX8031
K-razy Kritters ATR1001
Soccer THB 12003
Joust RX8044
Space Invaders CXL4008
Centipede CXL4020
Qix CXL4027
BASIC Computing Language CXL4002
Pitfall II CZ-011
and finally
H.E.R.O CZ-007


Are these worth anything? Probably not but I know next to nothing about the Atari 800.

Even still, I know enough to know there's something odd about the copy of H.E.R.O I have. It doesn't look anything like the others. In fact, I wonder if it might even be a prototype? Here's a picture.



Can anyone provide some insight for just what I might have? There's a single screw holding it together, but even after removing the screw, I can't figure out how to get the shell apart to take a look at the pcb. If the label is correct, I suspect to see an EPROM chip without a window. If so, should I cover it with black electrical tape before taking a pic? I'm a total noob when it comes to Atari 800. As much info as you guys can provide would be appreciated.

From the label alone you can tell it's a prototype, probably a sample copy sent out to magazines for reviewing.

So then......what could be its value?

Here's the section to put this under-

Prototype Central

Depends on a few factors:

Stage of development the prototype is in.
Whether the game is released or unreleased.
If a prototype has been found for this game.

I know this looks like a 2600 cart, but its definitely not. I don't know a whole lot about the Atari 800, but this cartridge is smaller and has a different number of connector pins. There's no way this is a 2600 game. I wish it were, as then I could test it and see what I've got going on.

No need to explain. It's clear from the first post it's a 800 cart (what's interesting is that the cart has the same style as the Spinnaker Kids on Keys cart rather than an Activision style cart), but prototype central is the correct forum for this. I'm no expert on protos, but maybe someone on the Atari Age forums would know. Also Krazy Kritters would need to be tested on an older non XL 400 or 800 since that game is known to have issues with the XL/XE line of Atari 8 bit computers.
