Radio Corporation of America
This page has been included in memory of one
of the early computer company that was the first to disappear. RCA abandoned
computers in 1971, its computer business have been taken over by Univac, the
rest of the company was bought by General Electric and the French group Thomson
in the 1980s.
Compagnie des Machines Bull was a close associate of RCA in the early 1960s,
before CMB was acquired by GE.
Computers built by RCA
- RCA 601
The RCA 601 was a large (7090 class) computer targeted towards
- RCA 501
The RCA 501 was the first computer designed as high-end general
purpose system. It might be noted that the system was sold in Europe by
English Electric as KDP-10.
- RCA 301
The RCA 301 was a business oriented medium sized computer introduced
in 1960 and sold in Europe by Siemens, ICT in United Kingdom (as ICT 1501)
and by Compagnie des Machines Bull as Gamma 30. A more detailed description
of this model can be found here.
- RCA 3301
The RCA 3301 was a a RCA 301compatible high-end system, planned to be
introduced in 1964. Compagnie des Machines Bull had prepared its
introduction under the name Gamma 40, when the company was bought by General
Electric. The RCA 3301 had a short life, being superseded by The Spectra
- RCA Spectra 70
The Spectra series were the first computer commercially available
that made use of integrated circuits designed in RCA labs. Its user mode
architecture was very similar to IBM S/360. The interrupt mechanism was
different as the supervisor mode. So, the Spectra line used different
operating system from IBM. Those systems was also sold by English Electric
(system 4) and by Siemens, as Siemens 4004. Siemens developed compatible
processors and BS/1000 operating system.
- During the period of the Unidata
project, the French Siemens computers was acquired by CII and French Siemens
4004 customers (many of them being ex-Gamma 30 users) became supported by
CII. The Serie X (where CII was a partner with Unidata 7740) was designed to
upgrade the RCA originated line.
- The line was continued and extended as Univac
- RCA 110
The RCA 110 was a process control computer developed in 1961. In
1962-1963, Bull envisioned to market that system and made several proposals
based on it. But Bull developed the Gamma M40 on the same market.
- RCA 4102
The RCA was a military computer developed in the early 1960s.
