I just acquired a Commodore 1541 floppy drive (along with two other Commodore computers) that has a ribbon cable coming out of the back of it. I opened the case, and the cable connects directly to pins under the 6522 chip (it looks like the chip was pulled, a second socket installed into the base socket, and some wires somehow attached the specific pins on the second socket, and then the 6522 chip put into the second socket.
I've read and seen videos on 1541 drive mods to make them PET compatible by building a PCB and a cable, and then burning a new kernal chip for the 1541 board. But the kernal in this 1541 looks original.
Before I starting checking continuity of this cable as to where each cable strand connects to the 6522, has anyone ever heard of this specific type of mod?
