THE BLAGBROUGH LEGACY

A Family Who Kept a Computer Alive

A heartfelt dedication to John and Betty Blagbrough (B & H Computers), whose tireless efforts kept the Tatung Einstein alive after Tatung discontinued the TC01 and 256 in the late 1980s. Through vision and commitment, they brought companies together to keep business and games software going, proving that family, friends and perseverance carry innovation forward.
