[9] [10] MicroSystems International CPS-1: MIL MF7114: 1973: Using a locally produced microprocessor based on the design of the Intel 4004. First built in 1972, a small number shipped in early 1973. [22] [23] Micral N: Intel 8008 [24] 1973: Awarded the title of "the first personal computer using a microprocessor" by a panel at the Computer ...
RCA CDP1802 die shot. The COSMAC (Complementary Symmetry Monolithic Array Computer) is an 8-bit microprocessor family introduced by RCA. It is historically notable as the first CMOS microprocessor. [1] The first production model was the two-chip CDP1801R and CDP1801U, which were later combined into the single-chip CDP1802. [2]
RCA Spectra 70 Model 46. RCA was one of a number of companies in the 1960s that entered the mainframe computer field to challenge the market leader International Business Machines (IBM). Although at this time computers were almost universally used for routine data processing and scientific research, in 1964 Sarnoff, who prided himself as a ...
From 1931 RCA produced a range of small mantel radios called the Superette, which at introduction sold for $57.50 not including the vacuum tubes. [5] [6] "Super" was derived from superheterodyne. Probably the most well known is the Model R-7, which was produced in several versions. RCA also produced a console version, the model R-9.
Dimensia (/ d ɪ ˈ m ɛ n s i ə / dih-MEN-see-uh) was RCA's brand name for their high-end models of television systems and their components (tuner, VCR, CD player, etc.) produced from 1984 to 1989, with variations continuing into the early 1990s, superseded by the ProScan model line. After RCA was acquired by General Electric in 1986, GE sold ...
The MC-10 includes a BASIC interpreter in ROM and uses regular audio cassettes for bulk storage. Text and graphics are displayed on a television set via a built-in RF modulator . Less common for machines in its class is the integrated RS-232 serial port , which allows the MC-10 to use line printers and modems without additional hardware.
The 1937 6F8G [2] was also an octal-based double triode with essentially the same characteristics as the 6SN7 (or two 6J5's), but in a 'Coke Bottle' large (Outline ST-12) glass envelope with a different pin arrangement and utilising a top cap connection for the first triode's grid (making pin 1 available for a metal shield).
The term All American Five (abbreviated AA5) is a colloquial name for mass-produced, superheterodyne radio receivers that used five vacuum tubes in their design. These radio sets were designed to receive amplitude modulation (AM) broadcasts in the medium wave band, and were manufactured in the United States from the mid-1930s until the early 1960s.
