Atanasoff–Berry Computer
阿塔纳索夫-贝瑞计算机 1937–1941

 http://www.net4info.de/photos/cpg/albums/userpics/10002/Atanasoff_Berry_Computer.gif

阿塔纳索夫-贝瑞计算机（Atanasoff–Berry Computer，通常简称ABC计算机）是世界上第一台电子数字计算设备[1]。这台计算机在1937年设计，不可编程，仅仅设计用于求解线性方程组，并在1942年成功进行了测试。然而，这台计算机用纸卡片读写器实现的中间结果存储机制是不可靠的。而且，在发明者约翰·文森特·阿塔纳索夫因为二战任务而离开爱荷华州立大学之后，这台计算机的工作就没有继续进行下去[2]。ABC计算机开创了现代计算机的重要元素，包括二进制算术和电子开关[3]。但是因为缺乏通用性、可变性与存储程序的机制，将其与现代计算机区分开来。这台计算机在1990年被认定为IEEE里程碑之一[4]。

阿塔纳索夫和克利福德·贝瑞的计算机工作直到1960年才被发现和广为人知，并且陷入了谁才是第一台计算机的冲突中。那时候，ENIAC普遍被认为是第一台现代意义上的计算机，但是在1973年，美国联邦地方法院注销了ENIAC的专利，并得出结论：ENIAC的发明者从阿塔纳索夫那里继承了电子数字计算机的主要构件思想。因此，ABC被认定为世界上第一台计算机。
