Umm...  you'll have to run that by me again.  If you have a Plus or SE (as I
assume you do; otherwise, why the interest in the Dove board?), buying Virtual
won't get you a thing--you've got to have the MMU.

According to my copy of Motorola's "MC68030 Enhanced 32-Bit Microprocessor
User's Manual", section 9, the '030 has the MMU built in.  The FPU, too.

Admittedly, the '020 needs an MMU to work with Virtual.

  The only drawback with morning is that it comes 
    at such an inconvenient time of day.

Nope! Not the '030!!!  The '040 is the first chip with an on-chip FPU (or at 
least parts of it).

So I've since been told.  Sorry, my mistake.

Wait a second here! You CANNOT run Virtual INIT on your MacPlus.
It REQUIRES the PMM.

The cheapest '030 _accelerator_ I believe is the Mercury board
from Total Systems. I _think_ it runs about $599.

There is also a board from Novy Systems called "Quick030" or
something like that that is similiarly priced.

I do not know how the performance of either of these compares with
an SE/30.

Speaking of upgrades.....do anyone know if Radius is going to offer an '030
for their SE accelerators?  I have a Radius accelerator....I would like
it to be a '030.   Radius are you listening?
