It's available via mail-order in Amigaworld.

>2) Is it a 68030/68882 or an '020.? (or 81/82 optional?)

The Midget Racer is 020 with room for the FPU.  The MegaMidgetRacer is 030,
again with room for an 68882.

>3) Does it take 32bit ram? (optional? at what extra cost?)

Yes.  There are two routes.  First there is a 512k Static RAM board.  This
is great for putting the ROM in for acclerated speed.  Second, there is
a 32bit RAM board available.  The board for the 2000 takes ZIPs.  The
older board for the 500 takes 256x4 or 1024x4.

>4) Does it have an MMU? (optional?)

The 030 version has the MMU native to the processor.  The 020 version has 
no provisions for an MMU.

No, the memory fall outside of the 'normal' Amiga 9-meg address range.

>6) Is it internal to the 500 or on a passthru bus?

Both the MR and the MMR (020 and 030 respectively) sit in the 68000's
position on the motherboard.   This is one accelerator that fits in
the 1000, 500, and the 2000.  The 68000 plugs into the {M}MR, thus
giving you 68000 mode when needed.

>7) Can toys such as SetCPU (1.6!) work with its 32bit ram? (an MMU?)
>   (this is moot if there is no mmu or 32bit ram..)

For the MMR 030, definitely.  I can't say for the 020 MR.
