	We have a number of Radius Accelerators at the office in SE's; mostly
16MHz, and one  25MHz board.

	They're great. If you know your way around the inside of a Mac, they're
not too hard to install, and they seem to be compatible with just about
everything that will run on a Mac II. For things that won't work, you can
turn off the accelerator. There's also a way to configure the accelerator's
code and data caches - any way you like, as long as it's on or off. :-)

	Some hard disk drivers are balky on the accelerator, but I don't
blame Radius for that; they've done really well. I recommend the use
of SilverLining for hard disks that you want to connect; if you use
their fast handshake, your drives will run incredibly fast and will
work with the accelerator.

	I also have an Accelerator on my Mac Plus at home, along with an
FPD interface. I had an incredible bitch of a time squeezing all that junk into
a chassis not designed to hold it, but even with 4MB, the machine doesn't
run too hot. I recommend a fan to cool the Mac.

	You can't turn off the Mac Plus version - that's a function of the
Mac Plus design, not of the Radius board.

	If you have a 68882 it will drop right in place of the 68881, and go
really fast on floating-point stuff.

	Radius' tech support is really good; the times I've had to call, the
staff has been knowledgable and responsive.

	I think they might have developer pricing (I'm not sure); if you're
a Certified Developer or Apple Partner or whatever they call it, give them
a call.

	I strongly recommend the Radius accelerators. (Did I already say that?)

	-- and no, there was no money, no free product, and no sexual favors
	that prompted this; I'm simply a satisfied customer.
