He does not know what the warehouse was used for as alot of the equipment was already vacant.  Anyways here are some pictures of the cards, hopefully someone may know what these are and how they are used.  As for the IIgs, it works fine, a little cruddy and yellow but it boots up.

Those look like scientific and/or automation related.  The first one has a large prototype area which seems the be the whole point of it so maybe for prototyping.   The second one has two 6522 chips on it which are interface/serial vias that must interface the pins that line the top of the card.  I would imagine these must have been interfaces for other specialized equipment but I couldn't fathom a guess as to what.
