No Go.  I desoldered my 68K and put in the 68010. Turn it on, the screen
clears, everything looks great!  The drive light comes on...

Then, bombs, the screen clears, and more bombs!  It keeps bombing till you
turn it off!

I looked through ST Internals and found some MOVE SR type instructions, in
the boot-up sequence, which are privileged on the '010, and not on the '000.

Now, I want to know if its my silly TOS version, that is, 1.0, which causes
this problem, and if it's been fixed for TOS 1.2 or 1.4.

Theoretically, TOS 1.6 should run....

I have some patches that I never implemented.  Perhaps I'll get the time
oneday....
