Buttobi!! CPU 1

Akira has been accumulating money for a computer for the last three years. When model 9821 goes on sale, he rushes to the shop only to discover that it has been sold out in less than 5 minutes! He is dejected and decides to go home when he comes across a guy in an alley who just happens to have the computer he was looking for. He is overjoyed and purchases the computer, only to get home to discover that he had purchased a 2198, a super-advanced bio-mechanical computer called Mimi, instead of a 9821.
