surface mount DRAM connector


Now I'm getting a better picture.  
Please correct me if I'm wrong.  

DRAM SIMMs
come in 72 pin modules even though the F21 prelim spec DRAM
pinout only shows 70 pins.

256K X 4 DRAMs are going to cost $ .50 plus 
the price of testing them to be sure they still work.

4Mbyte simms can cost $12...don't know if 1M X 32 is avail...

A 1M X 32 module would do the F21 in one socket, 
saving board space.  I like that approach for 72 pin simms,
especially since I found one source 
for a surf mount 72 pin simm socket.

Who can find a price and availability ofr a 1M X 32 simm?
