I thought that there were only a couple of NVRAM SIMMs available for
the Sparcs:
	* the SIMM for an SS-10/SS-20 (which fits in one of the two
	  `larger' SIMM sockets)
	* the SIMMs specifically for the SC-1000 (and maybe SC-2000)

I don't think Sun make an NVRAM SIMM for the Ultra series, although I
have put an SBus Presto card into an Ultra 2 and it worked.

I doubt that the Sun NVRAM SIMM would work in anything other than
the designated machine.


It would be nice if NetBSD could use the NVRAM SIMMs in the Sparcs, as
well as the equivalent Presto SIMMs in the DECsystem 5000/2xx's and 
on-board presto on the DECsystem 5500's.
