Abstract: The first extension card (112) has a microprocessor (123) which is connected to memory modules (SIMM) (122) by a high speed local bus (125). This feature permits high speed processing on the card and limits the number of input-output connecting pins to the main system and the second card (114). The second extension card (114) need not be of the same size as the first and the screw and strut (128, 130) used for mounting both first and second cards permits easy replacement on site of the cards and the (SIMM) memory modules. Protective covers (140) are fitted on either side of the cards.
