It's a IIfx.

The problem is that Apple never documented the IO Processors which
were supposed to make the IIfx blaze. So we don't know how to do much
of anything with it.

Since the Q900 and Q950 use the same IOP's, and the NetBSD/mac68k frontier
is getting near there, some folks have been trying to hack on them.

If you can (or are interested in learning how to) hack on the OS, you
might be in a good position to help. To really port to a new machine,
you need the machine, and a machine which you can use for development.
Your IIsi could serve as a development platform.. :-)

Take care,
