A full 68060 just won't work with only the adaptor in place. It requires an additional DiagRom to disable the FPU during startup.

There is something I was not aware of.
Full '040 and '060 cpus need to have their fpus disabled during boot.
Interesting.
Why?

You can use on the adapter a full 060, but you need a modified kickstart ROM with Exec.library.

I think Cosmos can help you with it.

Thank you (and Thomas) for the education.
The owner of the company I used to work for that built 68K based systems died as we were readying a 68030 model.

The jump from the '020-'030 cpus to the '040-'060 cpus is pretty complicated.

I'd already seen beta copies of Win 3.0 (from IBM) before we closed shop, so I felt kind of doomed anyway.

Nothing like realizing that market domination was going to result in an inferior system becoming the standard.
