Bletchley Park's National Museum of Computing is trying to find people who can repair its fleet of BBC Micro computers.
The museum has around 80 BBC Micro computers and is looking for volunteers familiar with the computer and its hardware.
While some BBC Micros are in display cases, a majority form part on an interactive exhibit that recreates a 1980s classroom.
Over the past year, more than 4,500 students have visited the museum on the Learning Programme, which lets them use an original BBC Micro to hack a computer game programme and for many, have their first experience at coding.
“It's one of the most popular parts of the Learning Programme and high on the list of requested activities for returning groups,” says the museum.
