The RCA 501 was a transistor computer manufactured by RCA beginning in 1958. RCA's pioneering work in transistors in other products provided its engineers with the basis needed to design effective use of transistors in early solid-state electronic computer systems as well.

2023年3月23日 · rca于1959年推出了全晶体管rca 501，这是一款中大型计算机，据销售手册表述，它是“世界上最先进的电子数据处理系统”。 它由工业设计师约翰·瓦索斯设计，采用了模块化设计策略，将计算机及其组件构建为一个系统，而不是单个单元。

2020年4月12日 · It turns out this machine crossed the pond: “English Electric-Leo-Marconi Computers worked with RCA to re-engineer the RCA501 to become the KDP10 (later the KDF8), aimed entirely at the emerging commercial marketplace” according to Grace’s Guide to British Industrial History

The RCA 501 is distinctively contemporary in spirit-fully access files, large high-speed printing capability, and increased mag- compatible with today's fine office interiors. Its trim, sheer look netic tape or magnetic core storage, to almost any extent desired.

The Radio Corporation of America (RCA) 501 System (Fig. 1) was designed specifically for a wide range of data processing applications. This paper describes the system and relates specific functional characteristics of the requirements that are found in data processing activities.

All New Design-Transistorization-Radical Expense Reduction-The RCA 501 is entirely new. It was designed especially to reap the many advantages of employing tran- sistors, printed wiring, modules and other techniques of miniaturization. New compactness and trim lines not only give the 501 the contemporary look; they also save floor space.

The RCA Model 501 Electronic Data Processing System (EDP), released in 1958, was the first commercial fully transistorized computer system, replacing the Vacuum Tube technology of the previous model, the RCA BIZMAC (released two years earlier in 1956).

The RCA (Radio Corporation of America), 501 Electronic Data Processing System is a complete and new system in the intermediate- and large-scale performance class. It is a general-purpose system using all transistor logic. The system has been under development for approximately 3 …
