An educational and entertainment device wherein a microcomputer is mounted in a housing to receive user generated data presented by moving a conducting stylus across perpendicular arrays of conductors on a work surface formed on the housing and presents information to the user via audio and visual devices. The conductors of each array are organized into first write groups formed of a plurality of interconnected conductors which can be placed in a selected electrical state by words written to the write groups and into read groups, read by the microcomputer, formed of a plurality of interconnected conductors interspersed with the conductors of the write groups. Additional, second write groups are interspersed with the first write groups and read groups. The arrays are alternatively mounted on the work surface or on a support member which can be detachably mounted on the work surface and connectors are provided for connecting the arrays on the support member to the microcomputer. The arrays are formed into a lamina by deforming arrays of wires with a die, injecting an insulating material in the interstices between the wires to form a lamina, and subsequently removing portions of the lamina adjacent the surface thereof.
