I don't get comp.sys.amiga.hardware, and this is pretty general interest.


Being the pround new owner of a 33MHz GVP 68030/68882 board, I decided
to remove my old 68010 from the motherboard and replace it with the
original 68000 (for compatibility reasons).  According to the GVP
documentation:

[p.15] "...If you anticipate the need to switch between 68030 mode and
        68000 mode frequently you may wish to mount a switch to the
        Amiga's rear panel and connect it to J11..."

I've done just that.

Now, my question:  Is there any problem with throwing that switch while
the machine is on (and perhaps, actually running)?  Obviously, I expect
it to crash the machine, but that's a moot point since I'm aiming to
reboot at that point anyway.  The way I see it, "power" is applied at
all times to both the 68000 and the 68030, it's just a matter of
redirecting the data.  I had a friend who's done this for about a year
with apparently no ill effects.
