Memory expansion for 3100?

[Paul Coppi]

Hi,
 Does anybody know how to go about expanding the memory on a 
DECstation 3100? We are considering purchasing DS3100s to run
some memory-hog applications. Unfortunately, we cannot currently
afford DEC's price for memory upgrades. Do any (cheaper) third
party vendors exist? On our Sun 3/60, upgrading memory consists 
simply of plugging in 1Mbitx9 SIMMS which cost < $200 each.
Can something similar be done with a DS3100?  (Unfortunately we
don't have a DS3100 to open up and look at.) If the DS3100 does 
use SIMMS, does anyone know their specifications ( 1Mbitx9, 1Mbitx8?
access time, manufacturer, part number, etc.)?

Thanks for your help.  We will post a summary of any replies
received.
