The 6801's do indeed have internal ROM on them, and they are uniquely programmed. So, you can't take the Master 6801 and swap it for the Tape 6801 for example. I do have some binary images of the different 6801s that I dumped. If you have access to a programmer (and fresh parts) you can burn them onto some new ones.
