[comp.sys.next] 4 MB SIMMS prices? Anyone put 4 MB SIMMS in their cube? What's the going price?

Do they work?

As far as I know they do. But what about having the basic 8 MB and adding
32 MB in 4 MB SIMMs? Does the cube recognize the configuration or would I have
to change anything (like jumpers, non volatile memory ...)?

And, of course most important of all: Where can I get 4 MB SIMMs? How much
do they cost?

Speaking about 4MB SIMMs, I've been wondering about something.  When the
NeXT comes up, it reports various I/O devices at addresses like
0x2000000 + something (such as SCSI, sound, etc.), which is an address
at the 32MB boundary.  I wonder if this could interfere with expanding
the machine past 32MB?  It should be able to take 64MB on the main board.
I suppose the machine could map the memory further up, past the I/O
physical addresses, and you'd never know the difference.  But has anyone
(including NeXT) run the thing with 64 (or 48) meg of RAM?
