==History==

'''Distributed Processing Technology''' (DPT) was founded in 1977, in Maitland, Florida. DPT was an early pioneer in computer storage technology, popularizing the use of disk caching in the 1980’s and 1990’s. DPT was the first company to design, manufacture and sell microprocessor-based intelligent caching disc controllers to the OEM computer market. Prior to DPT, disk caching technology had been implemented in proprietary hardware in mainframe computing to improve the speed of disk access.<ref name=obj6:3>{{cite journal|title=Maitland manufacturer's electronic part becomes darling of computer trade|journal=Orlando Business Journal|date=July 2-8, 1989|volume=6:3|url=http://www.stevegoldman.com/Publications/AboutSG/1989-07-02%20OBJ%20-%20Maitland%20Manufacturer's%20Electronic%20Part%20Becomes%20Darling%20of%20Computer%20Trade.pdf|accessdate=25 August 2014}}</ref><ref name=obj9:19/>
