41. Many audiophiles argue that high-end tube amplifiers give a " warmer " sound then their transistorized counterparts. 42. The first " fully transistorized " computer, built by IBM in 1954, had 2, 000 transistors. 43. Later they developed some of the first transistorized warning lights ( Visi-Flash trademark ) using standard 6v lantern batteries. 44. In Italy, Olivetti's first commercial fully transistorized computer was the Olivetti Elea 9003, being sold from 1959. 45. "' Boombox "'is a common term for a portable transistorized batteries as well as by line current. 46. A second application was a transistorized digital computer to be used in a Navy track-while-scan shipboard radar system. 47. He later helped to develop the first digital computers, the ILLIAC II, which was one of the first transistorized computers. 48. Philco's high-frequency surface-barrier transistors was also used in the circuitry design of the first transistorized supercomputer. 49. Ferranti prospered from the development effort as they adapted their new transistorized circuit design for a series of follow-on projects. 50. A digital electronic computer is not necessarily a transistorized computer : before the advent of the transistor, computers used vacuum tubes.
