> Ah yes, we had one of those too. I think we may have sold it in a garage sale a few years back. Only had four game cartridges. My dad was really good at Munch Man, a Pac-Man knockoff. I think we also had Space Invaders.

/me digs out his cartridges.

Addition & Subtraction 1. Basic (you'll pardon the pun) math, like counting, and single-digit addition and subtraction (hence the name) with non-negative answers. Note that I had this when I was in early elementary, and lost it forever soon after.

The Attack. Shoot spores, which are harmless by themselves but can turn into aliens, and aliens, which can destroy your ship. Then there are incubators, which are indestructible, and release spores or aliens (depending on the level) after counting down to 0 at varying speeds.

Blasto. Lotsa fun, especially with a second player. You (and maybe an opponent) drive a tank, see. You have a limited time to score as many points as you can manage. This may involve shooting mines and obstacles, or an opposing tank, or both. Shades of Combat for the Atari, if you ever played that.

Car Wars. You drive a car around a track, trying to pick up all the dots without crashing your car. Atari had one like that, too.

Chisholm Trail. Destroy all the rustlers to proceed, but watch out for the wranglers which can brand your steers by shooting at them. I couldn't get that much into the game.

Defender. This was good. It was like the Atari arcade game of the same name, only with use of a joystick instead of making you use buttons. (You used the space bar for smart bombs, though.)

Fractions 2. If this is Fractions 2, what was 1? Anyway, this involved addition and subtraction of fractions, and changing them to mixed numbers. And then it used the same few word problems. Interesting electrical theme.

Hunt the Wumpus. Nice logic game. Find and shoot the wumpus without falling into a slime pit of being eaten by the wumpus. A CGI version could probably be made without too much fuss on the technical end, as far as I can tell.

Moon Patrol. Like the arcade game of the same name. Pretty good.

Multiplication 1. Single-digit factors, I guess. Magician theme.

Munch Man. As mentioned, a Pac-Man clone. Only, you lay chain instead of eating dots. The nice thing about this is that the hoonos (who-knows) have different shapes depending on the level. Also, it gives you little encouraging messages when you complete a level.

Picnic Paranoia. Try to keep the ants from dragging your food off the blankets. Watch out for hornets, though. They're almost impossible to swat, and freeze you in the middle of the screen for WAY TOO LONG.

Pole Position. Like the arcade game, only with a joystick, and worse graphics.

TI Invaders. This is what you remembered as Space Invaders.

Tombstone City: 21st Century. Well, pardner, ya've got ta get rid of all the saguaro that are adjacent to each other, since they spawn morgs. It was okay, I guess.
