The specific question was related to Ricoh copying the 6502 and 
producing their own versions, with BCD disabled to avoid the patent. I'm 
not sure how many chips MOS made after 1989 (CIA's mostly) but the 
protection only lasts 10 years, so it should be fine now anyway.

For internal roms it becomes slightly more complex as they likely are 
still covered by copyright and if you publish an image of it then it's 
probably going to be recoverable. Very few MOS chips have internal roms 
and I don't imagine anyone has piles of cash to fight you posting 
something that old online.
