They’re Alive! Can YOU help keep them working?

Over the past year more than 4,500 students have visited The National Museum of Computing on the museum’s Learning Programme, and many of them used an original 1980s BBC Micro computer to hack a computer games program and perhaps gain their first experience of coding in BASIC. (The others used a BBC Micro emulator on a modern laptop.)

It’s one of the most popular parts of the Learning Programme and high on the list of requested activities for returning groups.

Now, the museum, which is based at Bletchley Park, Milton Keynes, is appealing for help in keeping their collection of about eighty hard-pressed ‘Beebs’ alive – and for more people to join their BBC refurb team.  It is looking for people familiar with the computer and its peripherals, including disk drives and monitors.

Two factoids demonstrate the endurance of TNMOC’s Beebs 33 years on:

  • 2,250 hours of BBC BASIC coding each year
  • 78,000 key presses per BBC computer annually

The Beeb has certainly stood the test of time. Teachers reminisce about their introduction to computing while the students get a thrill from this uncomplicated and rewarding introduction to computer programming.

Here’s a short video about the Learning Programme to give a flavour of how important these machines are in the context of learning about computer history.

The BBC Micro Cluster at TNMOC goes beyond the Learning Programme too. It’s used by the general public, visiting corporate groups and a few of the micros often escape on tour to external exhibitions and displays.  In addition, some machines form part of static displays.

The main problem that tends to occur with these otherwise robust Acorn computers is two capacitors in the power supply that dry out and, if not replaced, may explode with a very unpleasant smell. Thankfully, these are relatively easy to replace due to the design of the computer.

The TNMOC team changes the capacitors as part of standard procedures which can also include replacing sticky keys and the odd other component that may fail. They are, after all, getting on a bit, despite being tough as nails!

Keeping the BBC cluster going is down to the skills of a TNMOC volunteer team. So if you would like to apply to join that team, please email volunteering@tnmoc.org and see the Volunteering section on the TNMOC website.
