Those are the XDBus boards, identifying which won't tell you much. The
processor modules plug into the MBus. They're likely to be dual 50 MHz
modules, either with 1 MB secondary cache, or without. Find the part
number for the MBus modules and we can tell you more.

What IS 20 MHz, though, is the SBus on those boards.

The 501-2336 board is an FRU, while the 501-2541 came with the system and
had a pair of SM51 (50 MHz, 1 MB L2 cache) processor modules on the MBus.

Nah, your U1 is likely to be a whole lot faster in nearly every respect,
especially if it's the Enterprise 170, with its 100 Mbit ethernet and
fast/wide SCSI. The SS1000 will continue to perform under a much heavier
load, though, if it does indeed have 8 CPUs. Same caveats with any SMP
system. The SM51 isn't a slouch, but it is old and comparatively slow.

Total memory in the system and is installed in matched sets of four
modules. Traditionally, modules for this system were available in 8 and 32
MB sizes.

The 8 MB SIMMs have part number 501-1817 while the 32 MB variety have part
number 501-2196.

Solaris support for the sun4d first appeared in Solaris 2.2 and is
supported in Solaris 8, but "will be dropped any day now".

I think this machine is off topic for the list, though, by about two
years. (;
