Hello as I am surely not the first to think of this. Besides the case.
What parts would be needed to keep using the Pwd mkii once the upgrade is done.
I know it will need a display ? How much is that ?
Next what about the inputs on the back are they reused. Just asking and I am sure others here are wondering too.

The digital inputs are on the digital board (the one replaced in the MK II upgrade) and I assume the analog outputs are on the analog board so both should get replaced in the DS upgrade. I don’t think it is just the display that would need to be replaced but also the display board, which is not swapped out in the DS upgrade. I have no idea how standard those are or whether an off-the-shelf board would accept the proper firmware (but I’m not a techie).
