1981-era 8-bit BBC Micro computers and peripherals are displayed in a special interactive exhibit at the UK's National Museum of Computing designed to give modern students a taste of programming a vintage machine. Now, the museum is asking for help maintaining them. "We want to find out whether people have got skills out there that can keep the cluster alive as long as we can," said Chris Monk, learning coordinator at the organization.

"Owen Grover, a volunteer at the museum who currently helps maintain the cluster of BBC Micro machines, said they held up well despite being more than 30 years old. The BBC Micro was 'pretty robust,' he said, because it was designed to be used in classrooms. This meant that refurbishing machines for use in the hands-on exhibit was usually fairly straightforward. 'The main problem we need to sort out is the power supply,' he said. 'There are two capacitors that dry out and if we do not replace them they tend to explode and stink the place out. So we change them as a matter of course.'"
