I used to fix these all the time. UK schools were kicking them out by the skip load in the mid 1990s. I was there snagging them before they were collected. I had 30 BBC Bs and 12 Master machines at one point and a 1.5m tall pile of cumana disk drives.<p>Managed to shift them all on yahoo auctions and ebay between 1998-2001 making a small fortune.<p>However I really couldn't be bothered with it all today. Found something much smaller and easier to fix and post!
"Has about 80 BBC Micro computers... the majority form part of an interactive exhibit that recreates a 1980s classroom"<p>IME you only need one BBC Micro to recreate an 80s classroom.<p>At my school circa '82-'85 we had a beeb, a PET and two (different) Research Machines boxes that ran CP/M. That was all for the whole school, and with it we somehow managed to produce a remarkable portion of the UK's games programming talent.<p>I think I'd better tie an onion to my belt now...
