   Where can you get memory expansion boards for the cube?  What do they cost?

   I'm trying to decide between:
     * get 4x4MB and throw away 1x4MB of simms (20MB total, no free simm slots)
     * get expansion board and 1x4MB of simms  (16MB total, one bank open)
     * get expansion board and 4x4MB of simms  (24MB total, one bank open)

Assuming you're really talking about a cube (not a slab), you seem to
be making a mistake about the memory capacity on the CPU board. Cubes
have 16 SIMM slots, so you can put in up to 64 MB (16x4MB). If you buy
4 new 4MB SIMMs, you can just plug them in to 4 of the 8 slots that
are presently unfilled. You don't need any extra boards. Which is just
as well, because there don't seem to be any such products.

Now of course if what you have is a slab (not a cube), then you DO
have only 8 SIMM sockets. In that case you're limited to what you can
put in those positions (since there's no way to add on more memory
capacity). Which means only your first option is possible.

As far as I know, there ARE no expansion boards for a NeXT in terms of memory.

Wait a second, are we talking about a Cube or a Station?  The Cube has 16
SIMM slots, the Station has 8, which is what sounds like you're talking about.
The only machine that would require an expansion board (unless 64 megs isn't
big enough for you) would be the Station, which has no slots anyway.
