So, the two extra units that I backordered from NM (I was #205 in line when they were waiting for 200 units) have shipped, and I should be seeing them on wednesday -- at least that's what UPS trancking told me... Yay!
Now for the big question -- what to do with them? 
Also, if anyone has requests for things like me checking serial numbers, version numbers, motherboard/daughterboard numbers, things like that (as well as the TOS sticker), please post them in this thread or mail me directly (josh@open.com).
I was considering bumping my existing unit plus these two virginal ones up to 32MB. Is there a definitive reference for the chips needed, caps, etc for each of the different variations of this beastie?
