He was friends with another computer called Gordon, who had an IQ of 8,000 and was an Eleventh Generation AI hologrammatic computer. Gordon resembled Holly in that he was represented as a balding middle-aged man. Despite having a higher IQ than Holly, Gordon showed a lesser understanding of technology than Holly. One of the more worrying aspects of Holly's senility is that he has developed a blind spot for the number 7. When he invents the Holly Hop Drive, he claims that one mistake in his 13 billion calculations and they would be blown up. He then misses the seven in his countdown, possibly the cause of the error that sent them to the parallel universe.
