The first 680x0-based version of Cyberdog is 1.1 which also requires OpenDoc 1.1. OpenDoc 1.1 requires 32-bit ROMs in the computer. Therefore the OpenDoc 1.1 installer does not work on Macintosh II, IIx, IIcx, and SE/30 computers. Specifically, the OpenDoc 1.1 installer fails with this error, "Illegal instruction, Co-processor not installed."
Engineering is aware of this issue. They have no time frame for a solution, and there are no workarounds.
