Plain old cheap PC simms work fine. If you can, get non-parity as that was what it really called for, but I have successfully used parity in any mac I've tried (that require 72 pin simms that is... 30 pin ones will NOT work with parity for the most part... there are a few exceptions like the version of the IIci that was specifically designed TO use parity, as well as IIRC, some of the last models to use 30 pin would work with either style). You should be able to pick them up cheap from enough places. One thing in your favor... the Mac isn't very picky about matched simms, so you may be able to buy a bunch from somewhere like 18004memory.com that sells unmatched parts pretty cheap in their clearance section. -chris <http://www.mythtech.net>
