Thinking from scratch: Every part, every component had to be reconsidered, retooled
Take the keyboard. Conventional keyboards at that time used many control chips, so the cost incurred became naturally high. If the same keyboard were to be applied in the production of the MULTI it would only be too expensive. Realizing this, the team set out to make a keyboard that could be controlled with a single chip. Although now it is possible to arrange the price and component specifications, at the time it was a revolutionary way of thinking.
