Expansion Cards

Texas Instruments produced several expansion cards which fit into the PEB. All of these cards were encased in heavy duty aluminum cases which also acted as heat sinks. Later the cases were changed to plastic, in a move I assume, to save costs. Most (except the P-Code) can still be had without too much trouble.
