NEC provided a wirewrapped prototype, known as the PC-8001g. The Electronic Device Group only had a small distribution network of electronic parts stores, and the Information Processing Group only had corporate customers who purchased expensive mainframe computers. Also, they didn't have the capability for mass production. They asked New Nippon Electric (NEC Home Electronics since 1983) to sell the personal computers through their consumer distribution network. The system unit, displays and storage devices were all developed by NEC, and manufactured by New Nippon Electric. Printers were provided from Tokyo Denki (Toshiba TEC) because NEC had only developed expensive printers for mainframes. Other NEC divisions didn't appreciate the project before the PC-8001 went on sale. Most people, even in NEC, didn't know about microcomputers, and they couldn't understand what the Microcomputer Sales Section aimed for. The TK-80 sold well for computer enthusiasts, but the computer division regarded it as a toy. Their projects were often criticized inside the company. Watanabe recalled that engineers of the computer division criticized microcomputers didn't have parity bit checking, and they assumed the microprocessors of the time were not suitable for computing due to their lack of performance and reliability. He believed microprocessors were more reliable than wirewrapped minicomputers. When he circulated the contract with Microsoft for approval, computer division's director criticized they planned to purchase the software from a small company. Inside the company, it was considered engineers were confident in their softwares and had to develop softwares themselves. He explained to the director, "It's profitable, so there is no problem. We are salesmen." Watanabe knew importance of the industrial standard and third party developers, but his perception was against company's practice. Watanabe's bosses, Electronic Device Sales Division manager and executive director , let him do what he wanted. When he suggested the TK-80 project, Sawanobori supported him in anticipation that it would expand the microprocessor market, and Ouchi trusted their decision. When he planned to develop the personal computer, Ouchi wavered. It would become a computer product involved in NEC's core business, and would influence their corporate image. Watanabe also hesitated to develop it in the device division instead of the computer division, but he saw the burgeoning personal computer market in America, and then he decided to continue the project. As the project progressed, Watanabe, Sawanobori and Ouchi discussed their thoughts about marketing, planned a method for mass production, and reached an agreement
