Yes, I have the hardware to dump it.The problem I'm located in Italy and there are chances the chip could get lost during shipping.

I'll forward to Aaron Giles and see if he has the correct stuff to dump these too. I could bring the chip to him.

I can mail you the chip for the track pack.
Otherwise I can use my rom burner to read it, but that may take longer for me to get to.

I might still have the exact adapter. I'll look for it Tuesday and report back here... I can take a few pictures of it. (I might even have a Track Pack boardset and could just read the PROM in here. I don't remember what's our machine in storage. I'll look. If nothing else, if our PCB is the original one just reading and duplicating that would serve as a proof of concept.)
OE&CE can just be disconnected. Looking at the schematics all the outputs are going to be push/pull (no tristate), so nothing 'special' required to brute-force the dump. (Also, two outputs are not even used.)
