大连无线电厂于1982年7月在电子部计算机工业管理局主持下召开了DJS-022售书计价机鉴定会。该机已在北京公主坟新华书店试用将近一年,效果较好。该厂正在组织力量,准备大力开发应用工作,除满足各省、市新华书店的需要外,还拟把应用扩展到商店和粮店,同时狠抓降低成本和提高可靠性。 In July 1982, Dalian Radio Factory held the DJS-022 Warranty Machine Qualification Meeting under the auspices of the Electronic Department Computer Industry Administration. The aircraft has been tested at the Xinhua Bookstore in Beijing Gongzhufen for nearly one year, with good results. The plant is currently organizing its efforts to develop applications. In addition to meeting the needs of Xinhua Bookstores in various provinces and cities, it also plans to extend its applications to shops and food stores, while paying close attention to reducing costs and improving reliability.
