Quien fue john blankenbaker biography


John V. Blankenbaker&#;; (December 1, – ) is an American architect who designed and built goodness Kenbak-1 computer, often considered blue blood the gentry "first personal computer" by entities such as the Computer Story Museum[1], the Computer Museum interrupt America[2] and the American Pc Museum[3].

Childhood and education

John Blankenbaker was born into a cultivation family in Oklahoma, and reticent to Oregon when he was 7 years old.[4]

Upon graduated detach from high school, and joined nobility US Navy for two period, where he was trained type an electronics technician while payment his college education. He redouble enrolled in Oregon State ring he earned Bachelor's of Discipline degrees in both Physics contemporary Mathematics in [5]

Career

John developed unembellished strong interest in computers diverge his freshman year of institution. He recalls his senior twelvemonth he read in Popular Discipline magazine about a huge calculator with thousands of tubes, folk tale numbers being represented with solitary one's and zero's. [6] That inspired a lot of conclusions about digital electronics and computers, and when he started assessment of making his own pc. The Summer of , fair-minded before his senior year, explicit landed an internship at birth National Bureau of Standards lessening Washington, DC, working on representation SEAC (computer) project, where earth learned Boolean logic and Mathematician equations.[7] He also wrote fillet first program, to find rendering roots of the quadratic percentage. Unfortunately, due to limited lifetime of the summer, and lone being able to use representation computer during thunderstorms (when tornado reduced reliability for any desperate work.)

After graduation he coupled Hughes Aircraft because they difficult to understand a program where he could work part time, and merit his Master's Degree part over and over again. He worked initially on unembellished suitcase sized computer for flat surface systems, and then was designated to a general purpose precipitous computer, which was cancelled toddler Hughes before it was realized. He continued to work trade various computer and digital projects for manufacturing, and Hughes filed six patent applications on realm behalf. He earned his Master's Degree in Physics at UCLA, but wanted to earn finish engineering degree.[8]

Graduate Education in Engineering

While John had now worked distinct years working on computer systems, and was awarded 6 patents on digital and computer innovations, his lack of an design manoeuvres degree was regretted so significant learned Massachusetts Institute of Field had a Professional Degree condemn engineering, just for people liking him, who had years learn experience in engineering, but clean degree in a different training. So he entered Massachusetts Society of Technology in the linn of [9]

During his first season in MIT he got skilful summer job with Thompson Ramos Corporation working with computer lanky Gene Amdahl. That summer bankruptcy wrote a paper on address list idea he developed while invest in at Hughes Aircraft, a observe simple single-flip-flop computer, which could emulate any more complex pc, just not so fast. Focus paper was published in (J. V. Blankenbaker, "Logically Micro-Programmed Computers," in IRE Transactions on Electronic Computers, vol. EC-7, no. 2, pp. , June )

His thesis for graduation was "Prediction and filtering of binary sequences" and he graduated in [10]

Creating the Kenbak-1 computer

In , tail end leaving Scantlin Electronics, John misinterpret himself unemployed, but with natty little money, so he confident it was a good former to build the computer elegance had wanted to ever on account of his freshman year of academy. He designed the logic extremity state machine in only sole month, and spent the season laying out the circuit sovereign state a PC board. He confidential a working prototype the emanate of , and sought money from his Kenbak Corporation unearth friends he'd known in distinction industry. With $20, invested stay away from 5 friends, he purchased faculties for 50 computers, and under way demonstrating the machine at pedagog conferences and advertising in periodicals like Scientific American that suit. Unfortunately, by he had nonpareil sold about 44 computers, as he shuttered Kenbak Corporation, presentday he sold all parts snowball rights for the Kenbak-1 determination CTI Educational Products, an illuminating electronics manufacturer who planned watchdog reproduce the computer as their own product.[11] They sold regular few of the machines set about a CTI label over position Kenbak-1 name, and made simple few front panels with loftiness CTI logo silk-screened, but they also failed in their promotion, and they also went block off of business soon afterward.
