Maybe it's a crystal?  That'd be a high frequency for one IMO, though.

Hmmm...

How is the memory arranged on the machine?  The nice thing of having a 5c
keyboard is that the LEDs will tell you if the memory isn't good (like the SIMMs are
incorrectly put in, etc), etc.  I read this I believe from the SPARCstation LX manual,
which seems to apply with the SS2 I have as well (and shouldn't be much different from
the SS1/1+).

See what configuring the SIMMS are in.  SPARCs seem to be weird about
how the memory is placed from what I've seen...
