Fake cart? Bit Corp cart with exposed electronics?

[Carlos Fandango Jr]

I recently bought the Bit Corp cart in the photos, it works fine but has these strange exposed electronics.

Any ideas what this is?

Assume its a fake? As its also very clean, and the label looks brand new!

And if so what are those components e.g.c458 and how was this cart made?

looks legit to me

Can we see the label please?

Some more photos, including the labels. And a comparison of my other Bit Corp carts.

Mission & Squirrel -> I bought separately. Seem legit.

Postman & Open Sesame -> From same purchase batch and have the exposed electronics.

Any ideas? As I have never seen carts like the two on the right?

Why do you think they are fake? Is it because you can see what I assume is some sort of a resistor?  If that is the only thing you see wrong with it, I wouldn't worry.  I many examples of games like this.

Two resistors, a capacitor and a C458 transistor, it looks to me.

Just looked  at 3 Bit Corp carts and 2 had the same type of board

Awesome, thanks for checking and sending the photos..

I didn't know if they were fake or not.. basically because I had never seen carts with exposed resistors, capacitors etc.

Thanks again!

That's definitely weird, that resistors and those lovely Tantalum capacitors that explode when they wear out would be needed - especially when placed in front of the shielded area where the microchip resides behind... maybe the chips they used require less power, hence resisters, and the capacitor could be there to lessen the power-up stress of electricity flowing through. While merely and solely academic, it'd be fun to see a schematic for their design. I've not seen that very often. Or the resisters are used as a bug fix, not unlike how you can open up an old computer and sometimes see a wire affixed between two chips over the board rather than using a new PCB layout...?

As for item legitimacy, I'm pretty sure they're the real deals.

It is just an inverter circuit, nothing special.

Where did you acquire these?

It's legit, just another cheaper way to invert the chip select.  Parker also used this method every once in a while.

ebay, a while back
