Is it possible to use an earlier 256k or 512k ROM in a CC? I'm guessing the ROM is what determines whether the CC can run System 6 or not. When I insert a 6.0.8 disk it starts to load, then I get the "can't use" message. If an SE30, IIx, cx, ci, si or fx ROM (all 68030 system 6 & 7, color machines) were compatible with the CC socket, then theoretically I could run system 6 under the old ROM, though I might not have access to all of the CCs features. Any ideas? Where would I find info on the ROM chip specs to know which one might fit? Anybody have any of the aboev machines to check? Thanks.
