This a metal chassis open only at the front with 26 slots for PC cards.
It is populated with 12 cards, 3 of which are double width.
At the top of the card cage is a hinged panel that labels the slot types (not the card types).
Above the card cage is a panel with 26 connector slots and 2 D.C. power connectors on the right. 3 of the connector slots have dual BNC connector, 8 slots on the right have DB style connects, all of which have their cables cut, and the rest of the slots have blank panels. Each connect slot has a hinged panel that hangs down in front and labelsthe type of connection.
On the left side of the card cage is a vertical column of mixed 9 DB25 and5 DB9 connectors, all of which are labelled as to their function. 2 of the DB9 connectors labelled "CNET" have what appears to be termination plugs. 2 of the DB 25 connects have cables that go across the channel between card cage and connector slot that are cut on the right side of the chassis.
