These aren't quite what you're asking for, but they're the only boards
that I know of that come close.

Ariel Corp. has a board called the "S56", which is a SBus DSP56001 card.
It has a 56k running at 27 MHz, 16K or 64K of memory, and a NeXT-compatible
DB-15 that brings out the 56001's SSI serial port.  You can use this to
hook up A/D and D/A converters, etc.  Price is (I think) about $1500.

Berkeley Camera Engineering has a board called the "S56X", which is also
a SBus DSP56001 card.  It is also a 27 MHz 56k, comes with 32K of memory,
and has a LSI Logic DMA controller and a Xilinx 3030 or 3042 programmable
gate array.  The 56001's SSI port and some Xilinx pins are brought out on
a DB-37 (which, with an adaptor, can be made to look just like the NeXT
DB-15 port).  Price is (I think) about $2000.

The similarity of the product names can be explained by the fact that
Ariel sells the BCE S56X board as well.  BCE includes device driver
source code with their product, while Ariel only includes binaries.
BCE can probably offer slightly better technical support on the S56X,
since they designed it.

I've observed the S56X to do about 1.2 Mbytes/sec DMA into main memory
on a Sparc 1 (note that's to main memory, not to disk!).  Whether/how
long you can sustain 300 kbytes/sec to disk depends on a lot on your
disk, how much buffer space you can devote to I/O on the 56k, and what
else your sparc is doing.  The DMA controller on the S56X makes it much
more attractive for this sort of thing than the plain old S56,
however.  (In fact, the S56 may not be able to do this; I don't know,
I've never tried).

As to analog I/O boards, Ariel sells some stuff, and so does Spectrum
Signal Processing in Canada.  The Spectrum boards are for PCs, but they
can made to talk to the S56X.
