Hello,

I've decided to expand the memory in my cube.  
I ran the ROM monitor program and displayed the
memory configuration.  It said something like
SLOTS 0-3 have 4MB paged memory
SLOTS 4-7 have 4MB paged memory
SLOTS 8-11 have 0 memory
SLOTS 12-15 have 0 memory.

I have a couple questions regarding the addition
of SIMMS.

1) After reading the FAQ, I understand that SIMMs must
be added in sets of 4.

Does this mean a set of 4 identical capacity SIMMs?
Like can I add 2 1MB SIMMs and 2 4MB SIMMs to
make a set of four?  (My guess is NO, the must all
be of the same capacity.) 

2)  Can I buy a set of 4 4MB SIMMs and add them
to slots 8-11?  Or should I add them in slots
0-3 and move the 1MB SIMMS currently in those
slots to slots 8-11?  Does it matter??

3) Is the FAQ current with regard to vendors
selling the appropriate types of SIMMS that
work on the 68040 board??  Any other places to try??

Thanks,
Keith

Your guess is correct!

Doesn't matter.
