Chris is right - pull straight up.  Hard.  There is no magic to the 
Sparc memory slot design, it requires force.  Usually I use a good pair
of pliers to grab the exposed corners of the simms.

Sparc 1's and Sparc 2's are different w.r.t. memory placement.  On your
Sparc 1, the memory is in banks of 4 together.  You can put 4's in any of
the banks, as long as the entire bank is full of 4's.  Sparc 2's use
memory interleafing across the banks instead.
