The designs are stored, unencrypted, on the serial flash chip. The CPU contains firmware to encrypt this data, and send it to the cutter through the 10 pin port. If you get the data straight from the flash chip (either by desoldering, or attaching some wires, and suspending the CPU), the designs can be read and decoded. @Bill:The cartridge contains an Atmel CPU and a serial flash chip.

MTC created a file that was captured instead of actually sending the data stream to a Cricut. Make the cut got sued and the abiliity to backup your Cricut carts was lost. So while it's hard to decyrpt a cart, it has happened. At some point any encrypted data has to be decrypted to be used. That has always been the weak link in copy protection since.

From what I understand is part of the Atmels design is it's built in encryption. Hard hard to get decrypted. I think that's what Provo saw when they picked that design. What I don't know is if the data on the cart is still encrypted as it passes through the 10 pin port and decrypted prior to cutting. The George and shapes data is already in the Cricut which is why it doesn't need a cart. The firmware requires a cart to achieve a ready status. Provo just created a shunt for those three lines. On my own machine I used an old motherboard shunt with another pin connect with short wire where the ribbon cable connects the cart connect to Cricut motherboard. I never use cartridges myself.

I've been messing with lots of Cricuts with problems. Good news is even when i hook it up using make the cut, sure cuts alot, and designer studio, I just use the pc to enter and see. Not only that it's easier to use than the little screen. As long as designer studio can update provos firmware you can still use your Cricut. Just not standalone. The same way when the size wheel doesn't work. You don't use the wheel at all when you're using pc. There was a period where I got alot of Cricuts with wheel problem. They really liked their defects once they saved a lot of money by using a $5 USB cable and hook up a pc. The key is getting the Cricut firmware update. I've also got a few Cricuts that will not pass the first step where power and stop held the get the beep to start the update. I hope I can debug some of those dead boards using the code Arlet has.
