Early life
Youth
Prewitt grew up in the Daytona Beach, Florida area and lived there from 1963 to 1976. There he had his first exposure to auto racing; volunteering at Daytona International Speedway. He built his first computer in 1967 at 13. It performed simple math, which he disliked so much in school, and operated his phonograph.
He joined the Civil Air Patrol as a cadet and earned his way to the second highest rank (Cadet Lt. Colonel), learning leadership, search and rescue, about the military and the value of providing community service. Prewitt learned how to fly a plane, soloed at 16 and shortly thereafter earned his Private Pilots License at the youngest age allowed.
As a teenager, Prewitt learned sailing, fishing, boating and scuba diving and developed skills in mechanics, engineering, electronics, navigation and construction. After school and in summers, he worked at jobs building homes and in a restaurant washing dishes and cooking. In high school, he rented out the family houseboat. He was interested in painting and photography - he produced and sold a number of images.
After graduating high school, Prewitt continued building boats, managing his business and began to focus on computer programming. Between 1972-1975 he learned various programming languages using an IBM 1130. In the early 1970s, Prewitt dreamed of designing, building and selling a generation of small business computers with a price tag much less than the going rate of $50,000. Convinced that there was a market, Prewitt unsuccessfully sought venture capital to get his plans off the ground. In 1975, he built an Altair 8800. That same year, at the age of 21, Prewitt obtained his first business applications customer when he sold, designed and wrote computer programs for the IBM 5100 and System/32 as part of the business he had started at age 16. He joined the Sports Car Club of America (SCCA) and participated in autocross events.

Careers
Prewitt's working career began at the age of 13. He started in construction helping build homes for an Ormond Beach, Florida builder. He also worked busing tables and washing dishes before a promotion to cook at a couple of local restaurants. At 16, Prewitt started his first business. While attending community college, he built boats, worked as a painter, an accountant and for the yard crew at the Howard Boat Works marina. Prewitt's final jobs where he was employed by someone else were as a lab assistant helping students in his college and as a computer programmer for a company providing business applications on mainframes and mini computers.
Businesses
Ranger Systems
Prewitt started his first business when he was 16 and a junior in High School. "Ranger Systems", had four divisions: Ranger Manufacturing, Business World, Rent a Houseboat and Ranger Automotive Engineering.
He used the manufacturing part of the business to build electronics, computers and fiberglass boats from 13' fishing runabouts to a 40' houseboat. Business World did marketing, photography, printing and advertising. Prewitt wrote brochures, shot pictures, placed ads and ran a printing press. The biggest and most profitable division was Rent a Houseboat. Prewitt took the family boat and turned it into a rental business. He sometimes used a small boat to travel to school and quickly reach the houseboat. Prewitt did everything from writing contracts to maintenance. Prewitt frequently missed classes to unstop a toilet or revive the boat engine. The automotive division focused on repairs.
Prewitt operated Ranger Systems from 1970 to 1975 until his focus switched to computer programming and the personal computer industry.
International Computer
In 1975, Prewitt created International Computer to continue building, selling, installing and programming computers. This was the period when he started developing storage devices which ultimately became his most successful products.
He had customers that were located from mid to south Florida in manufacturing, hotel, service, legal, medical, construction and agricultural industries. Prewitt flew to their offices by initially renting aircraft and then by using his own.
Prewitt started Southeast Computer Consultants with a partner in late 1977.
Core International (Core)
In late 1979, Prewitt as sole owner created Core International from the assets of International Computer and Southeast Computer Consultants. Initially Core was created as a for-profit association of owners and operators of small IBM computers. It sold mail-order computer supplies and developed software for users of the IBM 5100, 5110 and IBM 5120 systems.
Prewitt built his first computer storage product for the IBM 5100 series because the machines did not have hard disk drives. Prewitt contracted with Control Data Corporation to manufacture the key component. Even though it was a niche product, the product became popular almost overnight when IBM discontinued its 5100 series and their customers turned to Core for parts and supplies. Within two years, Prewitt had sold $2.5 million worth of disk drives.
Core's second hardware and major software product also catered to the IBM orphans, a device and software that allowed IBM 5110/20 users to transfer data and programs from old bulky computers into new personal computers, which in 1981 were revolutionizing the computer industry. Core's software was called PC51 and allowed any DOS personal computer to use, unmodified, any BASIC program written for the IBM 5110/20 series computer. IBM consequently approached Core to become an IBM dealer. Customers could buy an integrated IBM PC, which completely replaced IBM's 5100 computers, or optionally attach their 5100 to Core's local area network, connecting all machines. These were revolutionary products and Core was the only source.
The company expanded internationally to include offices in Europe and Asia. In 1986, Inc Magazine selected Core as 21st in their annual list (Inc. 500) of the 500 fastest-growing private companies in the U.S.. By 1990, Core was well known as an industry leading developer of disk array, computer data storage and backup products. COREtest became the industry standard and most often quoted benchmark used to test, evaluate and compare performance of hard disk drives.
Many of Prewitt's products were the first of their kind, had no direct competition and were widely regarded for their superior performance and reliability. He was Chairman and Chief Executive Officer of Core until 1993 when the company was sold to Sony.
