This doesn't say how many memory banks are in the NeXTstation.  You
are right about documentation - it is almost non-existent with my 105M
system.

Ok,  again I must apologize since I get a lot of information from a variety of
sources, including actually popping the cover and "looking under the hood".
Monochrome NextStations take 8 simms.  You can mix groups in groups of
four 1 and 4 Mbyte 100ns or faster memory.  If you use parity memory, then
ALL the memory must be of that type.

Color Nextstations do not use the same memory!!!  They use either 256x32
or 1Mx32bit 80ns or faster memory (I think the memory moduals may be
physically different, though I have not checked "under the hood of a 
ColorNextstation).  A call to ClearPoint says they do not carry this memory
configuration.  Also you can put 256x36 memory if you want parity
check (I am unclear as to which of NeXT's color products support parity
memory checking at this point).

DSP memory is in a different packaging.

I am sorry if I was unclear about this earlier.
