Recently, I posted asking about the Magic 68030 accelerator carried by
Macproducts.  I received no responses about it specifically, but did receive a
few responses about other accelerators, summarized below.

I'm now throwing the floor open for other accelerators.  If you've got one
running in a Mac SE, I want to hear about it.  Do you love it, hate it, live
with it?  Why?  From a MacUser review, the MacPeak Orion accelerator looks
quite nice.  Anyone got one of those?  Please e-mail, I'll summarize.  

Summary follows; thanks to all those who responded.

Radius 68020 accelerator:

Has a fast RAM cache which shadows the RAM on the main board.

Accelerator can be turned on / off along with instruction and data caches from
a control panel which pops up when the machine boots with the mouse button
down.

TSI accelerators (phone # 800-874-2288 or 503-345-7395):

Motherboard memory goes to the accelerator, and original 1MB on main board is
restored.

The TSIs have ports for monitors from E-Machines and another monitor
manufacturer (didn't say which).

On the SE/30 upgrade:

Not really user-installable...

The upgrade is quite complicated, not only do you replace the motherboard, but
you also replace the steel frame that lies underneath the plastic case.  This
is because the SE/30's expansion slot is vertical, not horizontal, like the SE. 
Apple, of course, wants its old motherboard, 800K floppy, and steel frame back.
