Well yes, I think so. The RedEye interface is basically identical to the one Martin and Meindert made (see link below), but I used a ESP8266 instead and added a display. But the output is compatible, so using that one or mine connected to a RPi should work. The interface just returns the bytes sent from the calculator, so a small parser could collect the bytes and do what ever, ie. take a program listing and convert to a raw file.

But, there is always a but, syntehic textstrings are basically not allowed, since the calculator (at least the DM41X) doesn't send every character, so these are missed and have to manually be updated.
But normal programs "should" work ...
