Things are tough right now ...

They're tough for everyone :( But when coronavirus hit here in the UK, the museum had to close its doors to the public, and we lost practically all our income overnight.

Please Donate Via Just GivingNo visitors, no workshops, no events, no school visits... no income. We know that things are tough for everyone right now, but if you can afford to help us through these tough times please donate what you can.

Stay safe, stay at home! There's over 36,000 exhibits here! That should keep you occupied for a bit - get searching!

NEC jubilee/Economatics Computer Interface

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.

Date : Unknown

Manufacturer : Economatics

This exhibit has a reference ID of CH44355. Please quote this reference ID in any communication with the Centre for Computing History.
