The Inboard runs at 16 MHz, but with 2 wait states (it uses 120 ns DRAMS).
It still should have a significant edge over the AT clone in benchmarks
that don't involve disk i/o though.

Yes.  Of the 384K of "nonconventional" memory on the board, 128K is used
for ROM BIOS shadowing (optional) and internal uses, and is not otherwise
available.  The other 256K is available as extended memory, or it can be
converted to 192K of expanded memory.  The Inboard comes with custom
versions of the Super PC-Kwik cache software (uses extended memory) and
386-to-the-max (for memory mapping).

You can add either 1, 2, or 4 Megs.  The first two options via the
daughterboard which takes 256K chips and is available half- or fully-
populated, and the second via the daughterboard which uses 1 Meg chips and
is only available fully stuffed.  Current prices are roughly $350, $700,
and $1200 respectively (e.g., $349 for the 1 Meg from PC Connection in NH).
