Arium stuff

Anyone else here playing with Ariums? I have a spare ML4100 that is working, but no pods (well maybe I could be talked out of one), plus I have two pods for a later Arium: One is the 100Mgz logic pod LP-4050, and the other is an adapter (AD-4100) to use ML4100 pods with the later (SC-4400) harness. I'm looking for trades - I want the Arium option board that allows one to have 4,000 extra bits of storage plus the EEROM configuration storage. Otherwise I'd love to find an Arium ML-4400 which I think uses these pods...then I'd trade off my ML-4100s John :-#)#
