That's the point, isn't it? It's completely irrelevant *why* it's proprietary.

Because 8051s are off-the-shelf parts, only the firmware is proprietary, and once you have extracted the firmware (which people have), you can flash it into other off-the-shelf 8051s (or make a clean-room reimplementation).
The PAS is different, as it has its own ASICs. They are not standard chips with firmware in them. They are custom chips.
So you'd have to reverse-engineer the whole ASICs and reimplement them in whatever technology is suitable (perhaps FPGA). That's an entirely different ballgame. Software vs hardware.
Not to say that cloning a PAS isn't possible, just saying it's not comparable to cloning an SB. It's more complicated.
