This expansion board connects to the BBC Micro's user and analogue ports. It appears to be for use in an electronics lab or classroom environment. It provides the following features:

Two tactile button inputs
Eight DIP switch inputs
LED display of tactile/DIP switch states
Three analogue op-amps
One inverting schmitt trigger
Motor, with slotted disc interrupting an opto-isolator input
Connector for microphone input
Child board with three red, three green, and two amber LEDs. Connector is amrked "traffic light socket".
Off-board connectors for digital input/outputs and four analogue inputs.

While we have no documentation for this item, "NEC" is almost certainly not the PC manufacturer. Economatics were a UK company that supplied input/output control boxes and 'turtle' robots for Acorn (and later PC) computers.
